BUSINESS REVIEW AND PROSPECTS

BUSINESS REVIEW
In the first half of 2004, the Chinese government adopted a series of
macro-economic control measures, and achieved good results. The national
economy maintained an upward momentum of steady growth and GDP rose by 9.7%.
Demands for petroleum and petrochemical products continued to grow accordingly.
According to the Company's statistics, the apparent domestic consumption of
refined oil products (gasoline, diesel and kerosene including jet fuel) in the
first half of this year increased by 24.6% over the same period last year
whilst the apparent consumption of petrochemical products (in terms of
ethylene) increased by 15.59%.

In the first half of 2004, prices of international crude oil fluctuated at a
high level. Refining margin was improved and the chemical industries were in
the rising trend of a new cycle. The Company closely monitored the changes in
the domestic and overseas market of crude oil and petrochemical products, and
responsively adopted effective operation measures, actively explored the
market, optimised resources, rationalised structures, and maximised operation
volume. As a result, the oil and gas production increased steadily, oil
refining and petrochemical facilities operated at a high utilisation rate, the
sales of refined oil products increased significantly and marketing structures
were further optimised. At the same time, the Company further enhanced its
internal reform, streamlined the assets and reinforced internal control. As a
result of the joint efforts made by all the employees together with the
Company, the Company achieved remarkable operating results.

According to the PRC Accounting Rules and Regulations, the Company's income
from principal operations was RMB 265.71billion, up by 36.4% over the first
half of 2003. The Company's net profit was RMB 15.04 billion, up by 54.0% over
the first half of 2003. Based on the number of shares outstanding at the end of
the reporting period, earnings per share were RMB 0.17. According to the
International Financial Reporting Standards, turnover and other operating
revenues amounted to RMB 275.44 billion, up by 34.1% over the first half of
2003. Profit attributable to shareholders was RMB 16.15 billion, up by 50.6%
over the first half of 2003. Based on the number of shares outstanding at the
end of the reporting period, earnings per share were RMB 0.19.

The Board of Directors has decided to distribute an interim dividend of RMB
0.04 per share for the first half of 2004, which is equivalent to RMB 4.00 per
ADS.

1   PRODUCTION AND OPERATION

(1) Exploration and Production Segment
    In the first half of 2004, the average international crude oil price
    increased significantly compared with the same period last year. The
    Platt's global Brent spot price averaged USD 33.65 per barrel, up by 16.9%
    over the first half of 2003. Domestic prices of crude oil generally
    followed the trend in the international market. However, as there is a
    one-month time lag of domestic crude oil prices behind the international
    crude oil prices and the increase in international benchmarked prices for
    the Company's self-produced oil was not significant, the average crude
    price realised by the Company during the first half of 2004 was USD 29.62
    per barrel, up by 2.5% over the same period last year.


                               [GRAPHIC OMITTED]



    In the first half of 2004, the Company achieved good results in
    exploration, development and production of crude oil and natural gas.

    In exploration, the Company optimised exploration plan and profile of oil
    and gas reserves by taking the zone exploration as the main objective and
    the discovery of qualified proven reserves as the primary goal. New blocks
    in Tahe oilfield and deep layers in Jiyang trough demonstrated good
    indications of oil and gas reserves, and sound results were achieved in
    exploration in mature fields in eastern China. Important progress was
    achieved in the natural gas exploration blocks such as in northeastern
    Sichuan. Exploration wells in 6 key blocks in Ordos, Shengli, Zhongyuan,
    etc. obtained commercial oil and gas flow. In addition, oil and gas were
    discovered in a number of major exploration wells in the new blocks in
    western China. In the first half of 2004, the newly added proved geological
    reserves of crude oil amounted to approximately 133 million tonnes, whilst
    the newly added geological reserves of natural gas was approximately 62.3
    billion cubic meters.

    In development, the Company aimed to optimise its development plans and
    improve the quality of production capacity build-up. In the first half of
    2004, newly developed production capacity of crude oil and natural gas
    reached 2.29 million tonnes per year and 415 million cubic meters per year,
    respectively.

    In production, the Company seized the opportunity of high crude oil prices
    and carefully arranged oil and gas production. The Company exercised
    comprehensive management over its existing oilfields and consolidated its
    foundation for stable output, and the production of oil and gas increased
    steadily.

(2) Refining Segment
    In the first half of 2004, in response to the significant growth of demand
    in the domestic market, the Company made careful arrangement so as to
    ensure a safe, stable, sustained, optimal and full load operation of its
    facilities. The Company also made serious effects in increasing the
    processing volume of crude oil. In addition, the Company optimised the
    allocation of crude oil resources, further increased the processing volume
    of sour crude, optimised logistics and reduced production costs. The
    Company also optimised product mix, increased production of diesel and high
    value-added products and improved profitability. Furthermore, the Company
    enhanced its management over the operation of production facilities, and
    further improved major economic and technical indicators for oil refining,
    such as light product yield and refining yield.

for entering the World Trade Organization, the retail market of refined oil
products will open to foreign players by the end of this year, and the domestic
competition in the marketing of refined oil products may be more severe.

By following the changes in the market, the Company will take a proactive
approach, in production and management and minimize operational risks. In
addition, the Company will capture the opportunities in the market and invest
in and expedite the construction of major projects. Additionally, the Company
will deepen reform, reinforce internal management, expand resources and market,
improve efficiencies through staff reduction and ensure sustainable and
effective growth.

In Exploration and Production Segment, the Company intends to implement its
resources strategy to accelerate the exploration and development, to seek for
the addition of oil reserves in mature blocks in eastern China, breakthrough in
new exploration blocks in western China and discoveries in marine phase blocks
in southern China, as well as to speed up the construction of oil and gas
production capacity through developing newly found reserve in the existing
mature blocks and building auxilary facilities for production capacity in the
new blocks while reinforcing the production and operation management to reduce
the production costs of oil and gas. In the second half of 2004, the Company
plans to produce 138.2 million barrels of crude oil and 104.9 billion cubic
feet of natural gas.

In Refining Segment, the Company will closely monitor the changes of
international oil market, continue to optimise allocation of crude oil
resources, increase the processing volume of sour crude to reduce the
purchasing costs of crude oil. The Company intends to fully leverage the
Ningbo-Shanghai-Nanjing crude oil pipeline, optimise the allocation of crude
oil to reduce transportation costs. The Company will timely adjust product mix
in accordance with the market demand, reinforce operation management and ensure
safe, stable, sustainable, optimal and full-load operations. In addition, the
Company will proactively implement reform of marketing system of refined oil
products other than gasoline, diesel and jet fuel. The Company plans to process
67.46 million tonnes of crude oil in the second half of this year.

In Marketing and Distribution Segment, the Company intends to enhance the
distribution network of refined oil products by accelerating the construction
of refined oil product pipeline, optimising and adjusting the layout of oil
depots, as well as expanding the retail network. Following the principle of
achieving regional and professional management and flattening of the management
hierarchy, the Company intends to further carry out reform of its marketing
system of refined oil products. The Company will further improve service
quality and its corporate image. In the second half of 2004, the Company will
target its total domestic sales volume of refined oil products at 45.5 million
tonnes, including a retail volume of 25.37 million tonnes and a direct sales

   (1) Turnover and other operating revenues
       In the first half of 2004, the Company's turnover and other operating
       revenues were RMB 275.4 billion. Of which, turnover was RMB 265.7
       billion, up by 34.5% over the first half of 2003. This was mainly due to
       the fact that in the first half of 2004, prices of crude oil, petroleum
       products and chemical products all increased in the global market, and
       the Company seized the market opportunity to increase its refining
       throughput and sales volume of its refined products. As a result, the
       Company's sales volume of major petrochemical products increased
       significantly. The Company's other operating revenues was RMB 9.7
       billion, up by 26.1% over the first half of 2003. This was mainly due to
       the increase of sales revenue from its sale of raw and auxiliary
       materials and other products and services to China Petrochemical
       Corporation and its subsidiaries (excluding the Company) ("Sinopec
       Group") and to third parties.

       Most of crude oil and a small portion of natural gas produced by the
       Company were internally used for its refining and chemical production.
       The remaining was sold to the refineries owned by Sinopec Group and
       other customers. In the first half of 2004, external sales revenues of
       crude oil and natural gas amounted to RMB 7.4 billion, up by 4.1% over
       the first half of 2003, accounting for 2.7% of the Company's turnover
       and other operating revenues.

       The Company's Refining Segment and Marketing and Distribution Segment
       sell petroleum products (mainly consisting of refined oil products and
       other refined petroleum products) to third parties. In the first half of
       2004, the aggregate external sales revenues of petroleum products by
       these two segments were RMB 188.5 billion, up by 38.1% over the first
       half of 2003 and accounting for 68.4% of the Company's turnover and
       other operating revenues. The sales revenues of gasoline and diesel
       increased by 39.0% from that in the first half of 2003 to RMB 136.1
       billion, accounting for 72.2% of the total sales revenues of petroleum
       products.

       In the first half of 2004, the Company's external sales revenues of
       chemical products were RMB 50.9 billion, up by 33.6% over the first half
       of 2003, accounting for 18.4% of its turnover and other operating
       revenues.

   (2) Operating expenses
       In the first half of 2004, the Company's operating expenses were RMB
       248.1 billion, up by 32.8% over the first half of 2003. The operating
       expenses mainly consisted of the following:

       Purchased crude oil, products, and operating supplies and expenses

       The Company's purchase of crude oil, products and operating supplies and
       expenses were RMB 197.1 billion, up by 36.5% over the first half of
       2003, accounting for 79.5% of the operating expenses, of which:

       Purchase of crude oil was RMB 102.8 billion, up by 35.1% over the first
       half of 2003, accounting for 41.5% of the total operating expenses.

       To meet the increasing demands resulting from the rapid growth of the
       Chinese economy, the Company increased its refining throughput. In the
       first half of 2004, the Company's refining throughput was 63.26 million
       tonnes (excluding amounts processed for third parties), representing an
       increase of 15.67%, compared with that in the first half of 2003. The

       RMB 94.3 billion, up by 38.1% over the first half of 2003, accounting
       for 38.0% of the total operating expenses. This increase was mainly due
       to the increased costs of outsourced refined oil products and chemical
       feedstock.

       Selling, general and administrative expenses

       In the first half of 2004, the Company's selling, general and
       administrative expenses were RMB 14.2 billion, up by 24.4% over the

       o   Sales expenses, such as the costs of transportation, and other
           service charges etc. increased by RMB 1.2 billion, as a result of
           the increase in the sales volume of refined oil products and the
           increased proportion of retail and direct sales in total sales
           volume of refined oil products.

       amortization were RMB 14.8 billion, up by 14.1% over the first half of
       2003. The increase was mainly due to the addition of property, plant and
       equipment as a result of capital expenditure.

       Exploration expenses

       In the first half of 2004, the Company's exploration expenses were RMB
       2.5 billion, representing a decrease of 11.1% compared with that in the

       Taxes other than income tax

       In the first half of 2004, the Company's taxes other than income tax
       were RMB 7.8 billion, up by 25.6% over the first half of 2003. The
       increase was mainly attributable to the increase of consumption tax and
       surcharges as a result of the increase in sales volume of gasoline and
       diesel of the Company.




       Other operating expenses, net

       In the first half of 2004, the Company's other operating expenses (net)
       were RMB 3.0 billion, up by RMB 2.3 billion over the first half of 2003.
       The increase was mainly due to the fact that in order to allocate its
       internal resources more efficiently, the Company adjusted the production
       and operation plans for certain less efficient facilities in Chemicals
       and Marketing and Distribution segments, and accordingly made a
       provision for impairment of long-lived assets of RMB 2.3 billion
       representing the difference between the expected recoverable value and
       the net book value of these assets, up by RMB 2.1 billion over the first

       (6)  Taxation
            In the first half of 2004, the Company's income tax was RMB 7.7
            billion, up by 46.5% over the first half of 2003.

       (7)  Minority interests
            In the first half of 2004, the Company's minority interests were
            RMB 2.2 billion, up by 178.2% over the first half of 2003, mainly
            due to the significant increase in the profits from the Company's
            subsidiaries.

       (8)  Profit attributable to shareholders
            In the first half of 2004, the Company's profit attributable to

(1) Exploration and Production Segment
    Most of the crude oil and a small portion of the natural gas produced by
    the Exploration and Production Segment were used for the Company's refining
    and chemical operations. Most of the natural gas and a small portion of
    crude oil produced by the Company were sold to refineries owned by Sinopec
    Group and third party customers.

    In the first half of 2004, the operating revenues of this segment were RMB
    37.2 billion, up by 6.3% over the first half of 2003, which was mainly due
    to the increase of sales volume and the realised price of crude oil over
    that in the first half of 2003.

    In the first half of 2004, this segment sold 17.96 million tonnes of crude
    oil, up by 1.5% over the first half of 2003. 1.814 billion cubic meters of
    natural gas were sold, up by 10.2% over the first half of 2003. The average
    realised price of crude oil increased by 2.5% over the first half of 2003
    to RMB 1,742 per tonne (approximately USD 29.6/barrel); the average
    realised price of natural gas increased by 1.0% over the first half of 2003
    to RMB 607 per thousand cubic meters.

    In the first half of 2004, the operating expenses of this segment were RMB
    26.7 billion, up by 8.1% over the first half of 2003. This was mainly due
    to the increase of the oil and gas properties caused by the capital
    expenditure incurred in this segment. In the first half of 2004, the
    depreciation, depletion and amortization of the segment increased by
    approximately RMB 1 billion over the first half of 2003; other operating
    expenses increased by RMB 600 million over the first half of 2003; and the
    expenditure on land lease rentals and research and development increased by
    approximately RMB 200 million over the first half of 2003.

    In the first half of 2004, the Company's lifting cost for crude oil and
    natural gas was USD 6.28 per barrel, a slight increase from USD 6.26 per
    barrel recorded in the first half of 2003.

    In the first half of 2004, operating profit for the Exploration and
    Production Segment was RMB 10.5 billion, up by 2.2% over the first half of
    2003.

(2) Refining Segment
    The business activities of the Refining Segment consist of purchasing crude
    oil from the Company's Exploration and Production Segment and from third
    parties, processing crude oil into refined oil products, selling gasoline,
    diesel and kerosene to the Company's Marketing and Distribution Segment,
    selling other refined oil products externally to domestic and overseas
    customers by the Refining Segment.

    In the first half of 2004, operating revenues of the Refining Segment were
    RMB 161.3 billion, up by 23.0% over the first half of 2003, mainly because
    of increased sales volume of products and increase in the realised prices.


    The following table shows the sales volumes, average realised prices and
    the percentage change of various kinds of refined petroleum products of the
    segment between the first half of 2003 and the first half of 2004:

    other than gasoline, diesel and chemical feedstock were RMB 36.9 billion,
    representing an increase of 23.4% compared with that in the first half of
    2003, and accounting for 22.8% of this segment's operating revenues.

    In the first half of 2004, the segment's operating expenses were RMB 157
    billion, up by 22.2% over the first half of 2003, principally due to the
    increase of processing volume of crude oil and the high price of crude oil.

    In the first half of 2004, the average cost of crude oil was RMB 2,036 per
    tonne, representing an increase by 9.0% compared with that in the first
    half of 2003. Refining throughput was 63.26 million tonnes (excluding
    amounts processed for third parties), representing an increase of 15.67%
    compared with that in the first half of 2003. In the first half of 2004,
    the total crude oil costs were RMB 128.8 billion, accounting for 82.0% of
    the segment's operating expenses, representing an increase of 26.0%
    compared with that in the first half of 2003.

    In the first half of 2004, refining margin was USD 4.07 per barrel (defined
    as the sales revenues less the crude oil costs and refining feedstock costs
    and taxes other than income tax; divided by the throughput of crude oil and
    refining feedstock), up by USD 0.11 per barrel compared with USD 3.96 per
    barrel in the first half of 2003, representing an increase of 2.8%.

    as operating expenses less the purchasing costs of crude oil and refining
    feedstock, depreciation and amortization, taxes other than income tax,
    other operating expenses; and divided by the throughput of crude oil and
    refining feedstock) was USD 1.98 per barrel, down by USD 0.04 per barrel
    compared with USD 2.02 per barrel in the first half of 2003, representing a
    decrease of 2.0%.

    In the first half of 2004, operating profit of the Refining Segment was RMB
    4.3 billion, representing an increase of 60.8% compared with that in the
    first half of 2003.



(3) Marketing and Distribution Segment
    The business of Marketing and Distribution Segment includes purchasing
    refined products from the Refining Segment and third parities, conducting
    wholesale and direct sale to domestic users, and retailing, distributing
    refined products through the segment's retail and distribution network, as
    well as providing services related to refined product sales. In the first
    half of 2004, the operating revenues of this segment was RMB 158.2 billion,
    up by 41.2% over the first half of 2003, mainly due to the increase of
    sales volume and prices of refined products and the rationalization of
    marketing structure.

    In the first half of 2004, the sales of gasoline and diesel were RMB 137.2
    billion, which accounted for 86.7% of the operating revenues of this
    segment.

    The following table shows the sales volumes, average realised prices, and
    respective percentages of changes of the four product categories in the

    In the first half of 2004, this segment's operating expenses were RMB 149.7
    billion, up by 40.4% compared with that in the first half of 2003, mainly
    due to the increase of procurement costs, of which purchasing costs of
    gasoline and diesel were RMB 118.1 billion, constituting 78.9% of the
    segment's operating expenses, up by 37.0% over that in the first half of
    2003. In the first half of 2004, average purchased prices of gasoline and
    diesel went up by 0.8% and 9.6%, respectively, compared with that in the
    first half of 2003, to RMB 2,806 per tonne and RMB 2,741 per tonne,
    respectively. The purchasing volume of gasoline and diesel went up by 22.8%
    and 31.6%, respectively, compared with that in the first half of 2003, to
    13.36 million tonnes and 29.43 million tonnes, respectively.

    In the first half of 2004, the segment's cash operating cost per tonne of
    petroleum products (defined as the operating expenses less the purchasing
    costs, taxes other than income tax, depreciation and amortization, and
    divided by the sales volume) was RMB 153.4 per tonne, down by 6.0% compared
    with that in the first half of 2003. This decrease was primarily
    attributable to diluted expenses caused by increased total sales volume and
    decreased expenses as a result of flattened management hierarchy.

    In the first half of 2004, the Marketing and Distribution Segment's
    operating profit was RMB 8.6 billion, up by 56.9% over the first half of
    2003.



(4) Chemicals Segment
    The business activities of the Chemicals Segment include purchasing
    chemical feedstock from the Refining Segment and third parties, producing,
    marketing and distribution of petrochemical products.

    In the first half of 2004, operating revenues of the Chemicals Segment were
    RMB 58.4 billion, up by 32.5% over the first half of 2003, mainly because
    of increased sales volume of major chemical products and an increase in
    realised prices.

    The sales revenue from the Company's six categories of chemical products
    (i.e. basic organic chemicals, synthetic resin, synthetic rubber, synthetic
    fiber, synthetic fiber monomer and polymer and chemical fertilizer) totaled
    RMB 51.8 billion, accounting for 88.7% of the operating revenues of this
    segment, up by 34.3% over the first half of 2003.

  Notes on the Financial Statements
for the six-month period ended 30 June 2004

1   Status of the Company
    China Petroleum & Chemical Corporation (the "Company") was established on
    25 February 2000 as a joint stock limited company.

    According to the State Council's approval to the "Preliminary Plan for the
    Reorganisation of China Petrochemical Corporation" ( the "Reorganisation"),
    the Company was established by China Petrochemical Corporation ("Sinopec
    Group Company"), which transferred its core businesses together with the
    related assets and liabilities at 30 September 1999 to the Company. Such
    assets and liabilities had been valued jointly by China United Assets
    Appraisal Corporation, Beijing Zhong Zheng Appraisal Company, CIECC Assets
    Appraisal Corporation and Zhong Fa International Properties Valuation
    Corporation ("registered valuers"). The net asset value was determined at
    RMB 98,249,084,000. The valuation was reviewed and approved by the Ministry
    of Finance ("MOF") (Cai Ping Zi [2000] No. 20 "Comments on the Review of
    the Valuation Regarding the Formation of a Joint Stock Limited Company by
    China Petrochemical Corporation").

    In addition, pursuant to the notice Cai Guan Zi [2000] No. 34 "Reply to the
    Issue Regarding Management of State-Owned Equity by China Petroleum and
    Chemical Corporation" issued by the MOF, 68.8 billion domestic state-owned
    shares with a par value of RMB 1.00 each were issued to Sinopec Group
    Company, the amount of which is equivalent to 70% of the above net asset
    value transferred from Sinopec Group Company to the Company in connection
    with the Reorganisation.

    Pursuant to the notice Guo Jing Mao Qi Gai [2000] No. 154 "Reply on the
    Formation of China Petroleum and Chemical Corporation", the Company
    obtained the approval from the State Economic and Trade Commission on 21
    February 2000 for the formation of a joint stock limited company.

    The Company took over the exploration, development and production of crude
    oil and natural gas, refining, chemicals and related sales and marketing
    business of Sinopec Group Company after the establishment of the Company.

    Pursuant to the resolution passed at the extraordinary general meeting held
    on 24 August 2001, the Company acquired the entire equity interest of
    Sinopec National Star Petroleum Company ("Sinopec National Star") from
    Sinopec Group Company for a consideration of RMB 6.45 billion.

    Pursuant to the resolution passed at the Board of Directors' meeting held
    on 28 October 2003, the Company acquired the principal assets and
    liabilities related to the 380 Kiloton ethylene production and distribution
    equipments from Sinopec Group Maoming Petrochemical Company ("Sinopec
    Maoming"), for a consideration of RMB 3.3 billion (hereinafter referred to
    as the "Acquisition of Ethylene Assets").

    Pursuant to the resolution passed at the Board of Directors' meeting held
    on 29 December 2003, the Company acquired the entire operating assets and
    liabilities of Tahe Oilfield Petrochemical Factory ("Tahe Petrochemical")
    and Xi'an Petrochemical Main Factory ("Xi'an Petrochemical") from Sinopec
    Group Company, for considerations of RMB 0.14 billion and RMB 0.22 billion,
    respectively (hereinafter referred to as the "Acquisition of Refining
    Assets").

2   Significant accounting policies
    The significant accounting policies adopted by the Group are in conformity
    with the Accounting Standards for Business Enterprises and "Accounting
    Regulations for Business Enterprises" and other relevant regulations issued
    by the MOF of the PRC.

    (a)Accounting year
       The accounting year of the Group is from 1 January to 31 December.

    (b)Basis of consolidation
       The Group prepared the consolidated financial statements according to
       "Accounting Regulations for Business Enterprises" and Cai Kuai Zi [1995]
       No.11 "Provisional regulations on consolidated financial statements"
       issued by the MOF.

       The consolidated financial statements include the financial statements
       of the Company and all of its principal subsidiaries made up to 31
       December each year. Subsidiaries are those entities controlled by the
       Company. Control exists when the Company has the power, directly or
       indirectly, to govern the financial and operating policies of an entity
       so as to obtain benefits from its activities. The consolidated income
       statement of the Company only includes the results of the subsidiaries
       during the period when such control effectively commences until the date
       that control effectively ceases. The effect of minority interests on
       equity and profit/loss attributable to minority shareholders are
       separately shown in the consolidated financial statements.

       Where the accounting policies adopted by the subsidiaries are different
       from the policies adopted by the Company, the financial statements of
       the subsidiaries have been adjusted in accordance with the accounting
       policies adopted by the Company on consolidation. All significant
       inter-company balances and transactions, and any unrealised gains
       arising from inter-company transactions, have been eliminated on
       consolidation. For those subsidiaries whose assets and results of
       operation are not significant and have no significant effect on the
       Group's consolidated financial statements, the Company does not
       consolidate these subsidiaries, but includes in the long-term equity
       investments.

       For those jointly controlled entities which the Company has joint
       control with other investors under contractual arrangement, the Company
       consolidates their assets, liabilities, revenues, costs and expenses
       based on the proportionate consolidation method according to its
       percentage of holding of equity interest in those entities in the
       consolidated financial statements.

   (c) Basis of preparation
       The financial statements of the Group have been prepared on an accrual
       basis under the historical costs convention, unless otherwise stated.




2   Significant accounting policies (Continued)

   (d) Reporting currency and translation of foreign currencies The Group's
       financial statements are prepared in Renminbi. Foreign currency
       transactions during the period are translated into Renminbi at exchange
       rates quoted by the People's Bank of China ("PBOC rates") prevailing on
       the transaction dates. Foreign currency monetary assets and liabilities
       are translated into Renminbi at the PBOC rates at the balance sheet
       date. Exchange differences, other than those arising from foreign
       currency loans used to finance the construction of fixed assets before
       they are ready for their intended use are capitalised, are recognised as
       income or expenses in the income statement.

       The results of overseas subsidiaries are translated into Renminbi at the
       annual average PBOC rates. The balance sheet items are translated into
       Renminbi at the PBOC rates at the balance sheet date. The resulting
       exchange gains or losses are accounted for as foreign currency exchange
       differences.

   (e) Cash equivalents
       Cash equivalents held by the Group are short-term and highly liquid
       investments which are readily convertible into known amounts of cash and
       are subject to an insignificant risk of change in value.

   (f) Allowance for doubtful accounts
       Trade accounts receivable showing signs of uncollectibility are
       identified individually and allowance is then made based on the
       probability of being uncollectible. In respect of trade accounts
       receivable showing no sign of uncollectibility, allowance is made with
       reference to the ageing analysis and management's estimation based on
       past experience. Allowances for other receivables are determined based
       on the nature and corresponding collectibility. Specific approval from
       management is required for allowances made in respect of significant
       doubtful accounts.

   (g) Inventories
       Inventories, other than spare parts and consumables, are stated at the
       lower of cost and net realisable value. Difference between the cost and
       net realisable value of each category of inventories is recognised as
       provision for diminution in value of inventories. Inventories are
       measured at their actual cost upon acquisition. The cost of inventories
       is calculated using the weighted average method. In addition to the
       purchase cost of raw material, work in progress and finished goods
       include direct labour and appropriate proportion of production
       overheads, also computed using the weighted average method. Net
       realisable value is the estimated selling price in the ordinary course
       of business less the estimated costs of completion and the estimated
       costs and related taxes necessary to make the sale.

       Spare parts and consumables are stated at cost less any provision for
       obsolescence. Consumables are expensed when being consumed.

       Inventories are recorded by perpetual method.

   (h) Long-term equity investments
       The investment income and long-term equity investments related to the
       Group's investments in the associates and the Company's investments in
       subsidiaries, jointly controlled entities and associates are accounted
       for using the equity method. Equity investment difference, which is the
       difference between the initial investment cost and the Company's share
       of investors' equity of the investee enterprise, is accounted for as
       follows:

       Any excess of the initial investment cost over the share of
       shareholders' funds of the investee is amortised on a straight-line
       basis. The amortisation period is determined according to the investment
       period as stipulated in the relevant agreement, or 10 years if the
       investment period is not specified in the agreement. The amortisation is
       recognised as investment loss in the income statement in the relevant
       period.

       Any shortfall of the initial investment cost over the share of
       shareholders' funds of the investee is recognised in capital reserve -
       reserve for equity investment. Such shortfall is amortised on a
       straight-line basis over 10 years if the investment was acquired before
       the issuance of Cai Kuai [2003] No.10 "Questions and answers on
       implementing Accounting Regulations for Business Enterprises and related
       accounting standards (II)" on 7 April 2003.

       An associate is a company in which the Group holds, for long-term
       purposes, not less than 20% but not more than 50% of its equity
       interests and exercises significant influence in its management. A
       jointly controlled entity is an entity over which the Group can exercise
       joint control with other venturers.

       Long-term investments in entities in which the Group does not hold more
       than 20% of their equity interests or those in which the Group holds
       more than 20% of their equity interests but does not exercise
       significant influence in their management are stated at cost. Investment
       income is recognised when an investee enterprise declares a cash
       dividend or distributes profits.

       Disposals or transfers of long-term equity investments are recognised in
       investment income/losses based on the difference between the disposal
       proceeds and the carrying amount of the investments.

       Long-term equity investments are valued at the lower of the carrying
       amount and the recoverable amount. A provision for impairment of loss is
       made when the recoverable amount is lower than the carrying amount.




2   Significant accounting policies (Continued)

   (i) Fixed assets and construction in progress
       Fixed assets represent the assets held by the Group for production of
       products and administrative purpose with useful life over 1 year and
       comparatively high unit value.

       Fixed assets are stated in the balance sheet at cost or revalued amount
       less accumulated depreciation and impairment losses. Construction in
       progress is stated in the balance sheet at cost or revalued amount less
       impairment losses. Valuation is carried out in accordance with the
       relevant rules and regulations and fixed assets and construction in
       progress are adjusted to the revalued amounts accordingly.

       All direct and indirect costs related to the purchase or construction of
       fixed assets, incurred before the assets are ready for its intended use,
       are capitalised as construction in progress. Those costs included
       borrowing costs, which include foreign exchange gains or losses on
       specific borrowings for the construction of the fixed assets during the
       construction period.

       Construction in progress is transferred to fixed assets when the asset
       is ready for its intended use.

       Depreciation is provided to write off the cost of fixed assets over
       their estimated useful lives on a straight-line basis, after taking into
       account their estimated residual values.

       The respective estimated useful lives, residual values and annual
       depreciation rates on fixed assets are as follows:



                                                                             Depreciation                             Annual
                                                                                     life    Residual value depreciation rate

                                                                                                          
       Land and buildings                                                     15-45 years             3%-5%        2.1%-6.5%
-----------------------------------------------------------------------------------------------------
       Oil and gas properties                                                 10-14 years             0%-3%       6.9%-10.0%
       Plant, machinery, equipment and vehicles                                4-18 years                3%       5.4%-24.3%
-----------------------------------------------------------------------------------------------------
       Oil depots and storage tanks                                            8-14 years                3%       6.9%-12.1%
       Service stations                                                          25 years             3%-5%        3.8%-3.9%

       No depreciation is provided in respect of construction in progress.


   (j) Oil and gas properties
       Costs of development wells and the related support equipment are
       capitalised. The cost of exploratory wells is initially capitalised as
       construction in progress pending determination of whether the well has
       found proved reserves. Exploratory well costs are charged to expenses
       upon the determination that the well has not found proved reserves.
       However, in the absence of a determination of the discovery of proved
       reserves, exploratory well costs are not carried as an asset for more
       than one year following completion of drilling. If, after one year has
       passed, a determination of the discovery of proved reserves cannot be
       made, the exploratory well costs are impaired and charged to expense.
       All other exploration costs, including geological and geophysical costs,
       are charged to the income statement in the period as incurred.

   (k) Intangible assets
       Intangible assets are carried in the balance sheet at cost or valuation
       less accumulated amortisation and provision for impairment losses.
       Amortisation is provided on a straight-line basis. The amortisation
       period is the shorter of the beneficial period as specified in the
       related agreement and the legal life of the intangible asset.
       Amortisation is provided over 10 years if it is not specified in
       agreements or stipulated by law.

       Intangible assets include exploration and production right. Exploration
       and production right are amortised on a straight-line basis over the
       average period of the production rights of the related oil fields.

   (l) Pre-operating expenditures
       Except for the acquisition and constructions of fixed assets, all
       expenses incurred during the start-up period are aggregated in long-term
       deferred expenses and then fully charged to the income statement in the
       month operations commence.

   (m) Bonds payable
       Bonds payable is stated in the balance sheet based on the proceeds
       received upon issuance. Interest expenses are calculated using actual
       interest rate.

   (n) Revenue recognition
       Revenues associated with the sale of crude oil, natural gas, petroleum
       and chemical products and all other items are recorded when the customer
       accepts the goods and the significant risks and rewards of ownership and
       title have been transferred to the buyer. No revenue is recognised if
       there are significant uncertainties regarding recovery of the
       consideration due, the possible return of goods, or when the amount of
       revenue and the costs incurred or to be incurred in respect of the
       transaction cannot be measured reliably.

       When the outcome of a transaction involving the rendering of services
       can be estimated reliably, revenue from the rendering of services is
       recognised in the income statement in proportion to the stage of
       completion of the transaction based on the progress of work performed.
       When the outcome of the transaction involving the rendering of services
       cannot be estimated reliably, revenues recognised only to the extent
       that costs incurred are expected to be recoverable.

       Interest income is recognised on a time apportioned basis by reference
       to the principal outstanding and the rate applicable.




2   Significant accounting policies (Continued)

   (o) Income tax
       Income tax is the provision for income tax recognised in the income
       statement for the period using the tax effect accounting method. It
       comprises current and deferred tax.

       Deferred tax is provided using the liability method, for timing
       differences between accounting profit before tax and the taxable income
       arising from the differences in the tax and accounting treatment of
       income and expenses or loss.

       The tax value of losses expected to be available for utilisation against
       future taxable income is set off against the deferred tax liability
       within the same legal tax unit and jurisdiction. A valuation allowance
       is provided for the tax value of losses to reduce the deferred tax asset
       to the amount that is more likely than not to be realised through future
       taxable income.

   (p) Borrowing costs
       Borrowing costs incurred on specific borrowings for the construction of
       fixed assets are capitalised into the cost of the fixed assets during
       the construction period which brings the assets to their intended uses.

       Except for the above, other borrowing costs are recognised as financial
       expenses in the income statement when incurred.

   (q) Repairs and maintenance expenses
       Repairs and maintenance expenses, including cost of major overhaul, are
expensed as incurred.

   (r) Environmental expenditures
       Environmental expenditures that relate to current ongoing operations or
       to conditions caused by past operations are expensed as incurred.

   (s) Research and development costs
       Research and development costs are recognised as expenses in the period
       in which they are incurred.

   (t) Operating leases
       Operating lease payments are charged to the income statement on a
       straight-line basis over the period of the respective leases.

   (u) Dividends
       Dividends appropriated to shareholders are recognised in the profit
       appropriation statement when approved. Dividends proposed or approved
       after the balance sheet date but before the date on which the financial
       statements are authorised for issue are separately disclosed under
       shareholders' funds in on balance sheet.

   (v) Retirement benefits
       The contributions payable under the Group's retirement plans are charged
       to the income statement when the contribution becomes due in accordance
       with the terms of the plan.

   (w) Impairment loss
       The carrying amounts of long-lived assets are reviewed by the Group
       periodically in order to assess whether the recoverable amounts have
       declined below the carrying amounts. These assets are tested for
       impairment whenever events or changes in circumstances indicate that
       their recorded carrying amounts may not be recoverable. When such a
       decline has occurred, the carrying amount is reduced to the recoverable
       amount. The recoverable amount is the greater of the net selling price
       and the value in use. In determining the value in use, expected future
       cash flows generated by the asset are discounted to their present value.
       The amount of the reduction is recognised as an expense in the income
       statement.

       The Group assesses at each balance sheet date whether there is any
       indication that an impairment loss recognised for an asset in prior
       years may no longer exist. The provision for impairment loss is reversed
       if there has been a change in the estimates used to determine the
       recoverable amount by which the impairment loss is reduced. The reversed
       amount is recognised as income in the period in the income statement.

   (x) Related parties
       Parties are considered to be related to the Group if the Group has the
       ability, directly or indirectly, to control the party or exercise
       significant influence over the party in making financial and operating
       decisions, or vice versa, or where the Group and the party are subject
       to common control or common significant influence. Related parties may
       be individuals or entities.

43  Contingent liabilities
    (a)The Company has been advised by its PRC lawyers that, except for
       liabilities constituting or arising out of or relating to the business
       assumed by the Company in the Reorganisation, no other liabilities were
       assumed by the Company, and the Company is not jointly and severally
       liable for other debts and obligations incurred by Sinopec Group Company
       prior to the Reorganisation.

    (b)At 30 June 2004, guarantees given by the Group and the Company to banks
       in respect of banking facilities granted to the parties below are as
       follows:



                                                                     The Group                         The Company
                                                            At 30 June    At 31 December        At 30 June    At 31 December

------------------------------------------------------------------------------------------------------------------------------


       The Company monitors the conditions that are subject to the guarantees
       to identify whether it is probable that a loss has occurred, and
       recognises any such losses under guarantees when those losses are
       estimable. At 30 June 2004 and 31 December 2003, it is not probable that
       the Company will be required to make payments under the guarantees. Thus
       no liability has been accrued for a loss related to the Company's
       obligation under the guarantees arrangement.

    Environmental contingencies
    To date, the Group has not incurred any significant expenditure for
    environmental remediation, is currently not involved in any environmental
    remediation, and has not accrued any amounts for environmental remediation
    relating to its operations. Under existing legislation, management believes
    that there are no probable liabilities that will have a material adverse
    effect on the financial position or operating results of the Group. The PRC
    government, however, has moved and may move further towards more rigorous
    enforcement of applicable laws, and towards the adoption of more stringent
    environmental standards. Environmental liabilities are subject to
    considerable uncertainties which affect the Group's ability to estimate the
    ultimate cost of remediation efforts. These uncertainties include: i) the
    exact nature and extent of the contamination at various sites including,
    but not limited to refineries, oil fields, service stations, terminals and
    land development areas, whether operating, closed or sold; ii) the extent
    of required cleanup efforts; iii) varying costs of alternative remediation
    strategies; iv) changes in environmental remediation requirements; and v)
    the identification of new remediation sites. The amount of such future cost
    is indeterminable due to such factors as the unknown magnitude of possible
    contamination and the unknown timing and extent of the corrective actions
    that may be required. Accordingly, the outcome of environmental liabilities
    under proposed or future environmental legislation cannot reasonably be
    estimated at present, and could be material. The Group paid normal routine
    pollutant discharge fee of approximately RMB 113 million for the six-month
    period ended 30 June 2004 (2003: RMB 85 million).

    Legal contingencies
    The Group is a defendant in certain lawsuits as well as the named party in
    other proceedings arising in the ordinary course of business. While the
    outcomes of such contingencies, lawsuits or other proceedings cannot be
    determined at present, management is of the opinion that any resulting
    liabilities will not have a material adverse effect on the financial
    position or operating results of the Group.




44  Segmental information
    The Group has five operating segments as follows:

(i)    Exploration and production - which explores and develops oil fields,
       produces crude oil and natural gas and sells such products to the
       refining segment of the Company and external customers.

(ii)   Refining - which processes and purifies crude oil, which is sourced from
       the Exploration and Production Segment of the Group and external
       suppliers, and manufactures and sells petroleum products to the
       Chemicals and Marketing and Distribution Segments of the Company and
       external customers.

(iii)  Marketing and distribution - which owns and operates oil depots and
       service stations in the PRC, and distributes and sells refined petroleum
       products (mainly gasoline and diesel) in the PRC through wholesale and
       retail sales networks.

(iv)   Chemicals - which manufactures and sells petrochemical products,
       derivative petrochemical products and other chemical products to
       external customers.

(v)    Others - which largely comprise the trading activities of the import and
       export companies of the Group and research and development undertaken by
       other subsidiaries.

    The segments were determined primarily because the Group manages its
    exploration and production, refining, marketing and distribution, chemicals
    and others businesses separately. The reportable segments are each managed
    separately because they manufacture and/or distribute distinct products
    with different production processes and due to their distinct operating and
    gross margin characteristics. In view of the fact that the Company and its
    subsidiaries operate mainly in the PRC, no geographical segment information
    is presented.

    The Group evaluates the performance and allocates resources to its
    operating segments on an operating income basis, without considering the
    effects of finance costs or investment income. The accounting policies of
    the Group's segments are the same as those described in the Principal
    Accounting Policies (see Note 2). Corporate administrative costs and assets
    are not allocated to the operating segments; instead, operating segments
    are billed for direct corporate services. Inter-segment transfer pricing is
    based on cost plus an appropriate margin, as specified by the Group's
    policy.

    Reportable information on the Group's operating segments is as follows:

  Report of the International Auditors

[GRAPHIC OMITTED]

To the Shareholders of
China Petroleum & Chemical Corporation
(Established in The People's Republic of China with limited liability)

We have audited the interim financial statements on pages 77 to 103 which have
been prepared in accordance with International Financial Reporting Standards
promulgated by the International Accounting Standards Board.

RESPECTIVE RESPONSIBILITIES OF DIRECTORS AND AUDITORS

The Company's directors are responsible for the preparation of interim
financial statements which give a true and fair view. In preparing interim
financial statements which give a true and fair view it is fundamental that
appropriate accounting policies are selected and applied consistently, that
judgements and estimates are made which are prudent and reasonable and that the
reasons for any significant departure from applicable accounting standards are
stated.

It is our responsibility to form an independent opinion, based on our audit, on
those interim financial statements and to report our opinion solely to you, as
a body, and for no other purpose. We do not assume responsibility towards or
accept liability to any other person for the contents of this report.

BASIS OF OPINION

We conducted our audit in accordance with Statements of Auditing Standards
issued by the Hong Kong Society of Accountants. An audit includes examination,
on a test basis, of evidence relevant to the amounts and disclosures in the
interim financial statements. It also includes an assessment of the significant
estimates and judgements made by the directors in the preparation of the
interim financial statements, and of whether the accounting policies are
appropriate to the Group's circumstances, consistently applied and adequately
disclosed.

We planned and performed our audit so as to obtain all the information and
explanations which we considered necessary in order to provide us with
sufficient evidence to give reasonable assurance as to whether the interim
financial statements are free from material misstatement. In forming our
opinion we also evaluated the overall adequacy of the presentation of
information in the interim financial statements. We believe that our audit
provides a reasonable basis for our opinion.

OPINION

In our opinion, the interim financial statements give a true and fair view of
the state of affairs of the Group as at 30 June 2004 and of the Group's profit
and cash flows for the six-month period ended 30 June 2004 and have been
properly prepared in accordance with International Financial Reporting
Standards promulgated by the International Accounting Standards Board.

Notes:

(a)    According to the Company's Articles of Association, the Company is required to transfer 10% of its net profit, as
       determined in accordance with the PRC Accounting Rules and Regulations, to statutory surplus reserve until the reserve
       balance reaches 50% of the registered capital. The transfer to this reserve must be made before distribution of a
       dividend to shareholders.

       Statutory surplus reserve can be used to make good previous years' losses, if any, and may be converted into share
       capital by the issue of new shares to shareholders in proportion to their existing shareholdings or by increasing the par
       value of the shares currently held by them, provided that the balance after such issue is not less than 25% of the
       registered capital. During the six-month period ended 30 June 2004, the Company transferred RMB 1,504 million (2003: RMB
       977 million), being 10% of the current period's net profit determined in accordance with the PRC Accounting Rules and
       Regulations, to this reserve.

(b)    According to the Company's Articles of Association, the Company is required to transfer 5% to 10% of its net profit, as
       determined in accordance with the PRC Accounting Rules and Regulations, to the statutory public welfare fund. This fund
       can only be utilised on capital items for the collective benefits of the Company's employees such as the construction of
       dormitories, canteen and other staff welfare facilities. This fund is non-distributable other than on liquidation. The
       transfer to this fund must be made before distribution of a dividend to shareholders.

       Pursuant to the shareholders' approval at the Annual General Meeting on 18 May 2004, the Board of Directors was
       authorised to determine the amount of the transfer for the six-month period ended 30 June 2004. The directors authorised
       the transfer of RMB 1,504 million (2003: RMB 977 million), being 10% of the current period's net profit determined in
       accordance with the PRC Accounting Rules and Regulations, to this fund.

(c)    The usage of the discretionary surplus reserve is similar to that of statutory surplus reserve.

(d)    According to the Company's Articles of Association, the amount of retained profits available for distribution to
       shareholders of the Company is the lower of the amount determined in accordance with the PRC Accounting Rules and
       Regulations and the amount determined in accordance with IFRS. At 30 June 2004, the amount of retained profits available
       for distribution was RMB 26,804 million, being the amount determined in accordance with the PRC Accounting Rules and
       Regulations. Interim dividend of RMB 3,468 million (2003: RMB 2,601 million) proposed after the balance sheet date has
       not been recognised as a liability at the balance sheet date.

(e)    The capital reserve represents (i) the difference between the total amount of the par value of shares issued and the
       amount of the net assets transferred from Sinopec Group Company in connection with the Reorganisation and (ii) the
       difference between the considerations paid over the amount of the net assets acquired from Sinopec National Star, Sinopec
       Maoming, Xi'an Petrochemical and Tahe Petrochemical.

(f)    The application of the share premium account is governed by Sections 178 and 179 of the PRC Company Law.

NOTES ON THE INTERIM FINANCIAL STATEMENTS for the six-month period ended 30
June 2004

1   PRINCIPAL ACTIVITIES, ORGANISATION AND BASIS OF PRESENTATION

    Principal activities
    China Petroleum & Chemical Corporation (the "Company") is an energy and
    chemical company that, through its subsidiaries (hereinafter collectively
    referred to as the "Group"), engages in fully integrated oil and gas and
    chemical operations in the People's Republic of China (the "PRC"). Oil and
    gas operations consist of exploring for, developing and producing crude oil
    and natural gas; transporting crude oil, natural gas and products by
    pipelines; refining crude oil into finished petroleum products; and
    marketing crude oil, natural gas and refined petroleum products. Chemical
    operations include the manufacture and marketing of a wide range of
    chemicals for industrial uses.

    Organisation
    The Company was established in the PRC on 25 February 2000 as a joint stock
    limited company as part of the reorganisation (the "Reorganisation") of
    China Petrochemical Corporation ("Sinopec Group Company"), the ultimate
    holding company of the Group and a ministry-level enterprise under the
    direct supervision of the State Council of the PRC. Prior to the
    incorporation of the Company, the oil and gas and chemical operations of
    the Group were carried on by oil administration bureaux, petrochemical and
    refining production enterprises and sales and marketing companies of
    Sinopec Group Company.

    As part of the Reorganisation, certain of Sinopec Group Company's core oil
    and gas and chemical operations and businesses together with the related
    assets and liabilities that were to be transferred to the Company were
    segregated such that the operations and businesses were separately managed
    beginning 31 December 1999. On 25 February 2000, in consideration for
    Sinopec Group Company transferring such oil and gas and chemical operations
    and businesses and the related assets and liabilities to the Company, the
    Company issued 68.8 billion domestic state-owned ordinary shares with a par
    value of RMB 1.00 each to Sinopec Group Company. The shares issued to
    Sinopec Group Company on 25 February 2000 represented the entire registered
    and issued share capital of the Company at that date. The oil and gas and
    chemical operations and businesses transferred to the Company related to
    (i) the exploration, development and production of crude oil and natural
    gas, (ii) the refining, transportation, storage and marketing of crude oil
    and petroleum products, and (iii) the production and sale of chemicals
    (collectively the "Predecessor Operations").

    Basis of presentation
    Pursuant to the resolution passed at the Extraordinary General Meeting held
    on 24 August 2001, the Company acquired the entire equity interest of
    Sinopec National Star Petroleum Company ("Sinopec National Star") from
    Sinopec Group Company for a consideration of RMB 6.45 billion (hereinafter
    referred to as the "Acquisition of Sinopec National Star").

    Pursuant to the resolution passed at the Directors' meeting on 28 October
    2003, the Group acquired the equity interest of Sinopec Group Maoming
    Petrochemical Company ("Sinopec Maoming") from Sinopec Group Company, for a
    consideration of RMB 3.3 billion (hereinafter referred to as the
    "Acquisition of Ethylene Assets").

    Pursuant to the resolution passed at the Directors' meeting on 29 December
    2003, the Group acquired the equity interest of Xi'an Petrochemical Main
    Factory ("Xi'an Petrochemical") and Tahe Oilfield Petrochemical Factory
    ("Tahe Petrochemical") from Sinopec Group Company, for considerations of
    RMB 221 million and RMB 135 million, respectively (hereinafter referred to
    as the "Acquisition of Refining Assets").

    As the Group, Sinopec National Star, Sinopec Maoming, Xi'an Petrochemical
    and Tahe Petrochemical are under the common control of Sinopec Group
    Company, the Acquisition of Sinopec National Star, the Acquisition of
    Ethylene Assets and the Acquisition of Refining Assets are considered as
    "combination of entities under common control" which are accounted in a
    manner similar to a pooling-of-interests ("as-if pooling-of-interests
    accounting"). Accordingly, the assets and liabilities acquired from Sinopec
    National Star, Sinopec Maoming, Xi'an Petrochemical and Tahe Petrochemical
    have been accounted for at historical cost and the financial statements of
    the Group for periods prior to the combination have been restated to
    include the results of operations of Sinopec National Star, Sinopec
    Maoming, Xi'an Petrochemical and Tahe Petrochemical on a combined basis. In
    connection with these acquisitions, certain assets, primarily property,
    plant and equipment and construction in progress, were retained by Sinopec
    Group Company. The assets retained by Sinopec Group Company were reflected
    as a distribution in the shareholders' funds. The considerations for these
    acquisitions were treated as an equity transaction.

    The results of operations previously reported by the Group for the
    six-month period ended 30 June 2003 have been restated to include the
    results of Sinopec Maoming, Xi'an Petrochemical and Tahe Petrochemical
    (collectively the "Acquired Group") as set out below.



                                                                               The Group

                                                                            reported)         Group             Combined
                                                                            RMB               RMB               RMB

---------------------------------------------------------------------------------------------------------------------------

    For the period presented, all significant transactions between the Group and the Acquired Group have been eliminated.





1   PRINCIPAL ACTIVITIES, ORGANISATION AND BASIS OF PRESENTATION (Continued)

    The accompanying interim financial statements have been prepared in
    accordance with IFRS promulgated by the International Accounting Standards
    Board. IFRS includes International Accounting Standards ("IAS") and related
    interpretations. These interim financial statements also comply with the
    applicable disclosure provisions of the Rules Governing the Listing of
    Securities on The Stock Exchange of Hong Kong Limited.

    The accompanying interim financial statements are prepared on the
    historical cost basis as modified by the revaluation of certain property,
    plant and equipment (Note 14). The accounting policies described in Note 2
    have been consistently applied by the Group.

    The preparation of the interim financial statements in accordance with IFRS
    requires management to make estimates and assumptions that affect the
    reported amounts of assets and liabilities and disclosure of contingent
    assets and liabilities at the date of the interim financial statements and
    the reported amounts of revenues and expenses during the period. Actual
    results could differ from those estimates.

2   PRINCIPAL ACCOUNTING POLICIES

    (a)Basis of consolidation
       The consolidated interim financial statements include the interim
       financial statements of the Company and its subsidiaries. Subsidiaries
       are those entities controlled by the Company. Control exists when the
       Company has the power, directly or indirectly, to govern the financial
       and operating policies of an entity so as to obtain benefits from its
       activities.

       The results of subsidiaries are included in the consolidated income
       statement from the date that control effectively commences until the
       date that control effectively ceases, and the share attributable to
       minority interests is deducted from or added to profit from ordinary
       activities after taxation. All significant inter-company balances and
       transactions and any unrealised gains arising from inter-company
       transactions are eliminated on consolidation.

       The particulars of the Group's principal subsidiaries are set out in
Note 31.

    (b)Translation of foreign currencies
       The functional and reporting currency of the Group is Renminbi. Foreign
       currency transactions during the period are translated into Renminbi at
       the applicable rates of exchange quoted by the People's Bank of China
       ("PBOC rates") prevailing on the transaction dates. Foreign currency
       monetary assets and liabilities are translated into Renminbi at the PBOC
       rates at the balance sheet date.

       Exchange differences, other than those capitalised as construction in
       progress, are recognised as income or expense in the income statement.

    (c)Cash and cash equivalents
       Cash equivalents consist of time deposits with financial institutions
       with an initial term of less than three months when purchased. Cash
       equivalents are stated at cost, which approximates fair value.

    (d)Trade accounts receivable
       Trade accounts receivable are stated at cost less allowance for doubtful
       accounts. An allowance for doubtful accounts is provided based upon the
       evaluation of the recoverability of these accounts at the balance sheet
       date.

    (e)Inventories
       Inventories, other than spare parts and consumables, are stated at the
       lower of cost and net realisable value. Cost includes the cost of
       purchase computed using the weighted average method and, in the case of
       work in progress and finished goods, direct labour and an appropriate
       proportion of production overheads. Net realisable value is the
       estimated selling price in the ordinary course of business less the
       estimated costs of completion and the estimated costs necessary to make
       the sale.

       Spare parts and consumables are stated at cost less any provision for
       obsolescence.




2   PRINCIPAL ACCOUNTING POLICIES (Continued)

    (f)Property, plant and equipment
       An item of property, plant and equipment is initially recorded at cost,
       less accumulated depreciation and impairment losses. The cost of an
       asset comprises its purchase price and any directly attributable costs
       of bringing the asset to working condition and location for its intended
       use. Subsequent to the revaluation (Note 14), which was based on
       depreciated replacement costs, property, plant and equipment are carried
       at revalued amount, being the fair value at the date of the revaluation
       less any subsequent accumulated depreciation and impairment losses.
       Revaluations are performed periodically to ensure that the carrying
       amount does not differ materially from that which would be determined
       using fair value at the balance sheet date. Expenditure incurred after
       the asset has been put into operation is capitalised only when it
       increases the future economic benefits embodied in the item of property,
       plant and equipment. All other expenditure is charged to the income
       statement in the period in which it is incurred.

       Gains or losses arising from the retirement or disposal of property,
       plant and equipment, other than oil and gas properties, are determined
       as the difference between the net disposal proceeds and the carrying
       amount of the asset and are recognised as income or expense in the
       income statement on the date of retirement or disposal. On disposal of a
       revalued asset, the related revaluation surplus is transferred from the
       revaluation reserve to retained earnings.

       Depreciation is provided to write off the cost/revalued amount of each
       asset, other than oil and gas properties, over its estimated useful life
       on a straight-line basis, after taking into account its estimated
       residual value, as follows:

       Buildings                                               15 to 45 years
       Plant, machinery, equipment, oil depots and others       4 to 18 years
       Service stations                                        25 years

    (g)Oil and gas properties
       The Group uses the successful efforts method of accounting for its oil
       and gas producing activities. Under this method, costs of development
       wells and the related support equipment are capitalised. The cost of
       exploratory wells is initially capitalised as construction in progress
       pending determination of whether the well has found proved reserves. The
       impairment of exploratory well costs occurs upon the determination that
       the well has not found proved reserves. Exploratory wells that find oil
       and gas reserves in any area requiring major capital expenditure are
       expensed unless the well has found a sufficient quantity of reserves to
       justify its completion as a producing well if the required capital
       expenditure is made, and drilling of the additional exploratory wells is
       under way or firmly planned for the near future. However, in the absence
       of a determination of the discovery of proved reserves, exploratory well
       costs are not carried as an asset for more than one year following
       completion of drilling. If, after one year has passed, a determination
       of the discovery of proved reserves cannot be made, the exploratory well
       costs are impaired and charged to expense. All other exploration costs,
       including geological and geophysical costs, other dry hole costs and
       annual lease rentals, are expensed as incurred. Capitalised costs
       relating to proved properties are amortised at the field level on a
       unit-of-production method. The amortisation rates are determined based
       on oil and gas reserves estimated to be recoverable from existing
       facilities over the shorter of the economic lives of crude oil and
       natural gas reservoirs and the terms of the relevant production
       licenses.

       Gains and losses on the disposal of proved oil and gas properties are
       not recognised unless the disposal encompasses an entire property. The
       proceeds on such disposals are credited to the carrying amounts of oil
       and gas properties.

    (h)Lease prepayments
       Lease prepayments represent land use rights paid to the PRC's land
       bureau. Land use rights are carried at cost and amortised on a
       straight-line basis over the respective periods of the rights.

    (i)Construction in progress
       Construction in progress represents buildings, oil and gas properties,
       various plant and equipment under construction and pending installation,
       and is stated at cost less impairment losses. Cost comprises direct
       costs of construction as well as interest charges, and foreign exchange
       differences on related borrowed funds to the extent that they are
       regarded as an adjustment to interest charges, during the periods of
       construction.

       Construction in progress is transferred to property, plant and equipment
       when the asset is substantially ready for its intended use.

       No depreciation is provided in respect of construction in progress.

    (j)Investments
       Investments in unlisted equity securities are stated at cost less
       provision for impairment losses. A provision is made where, in the
       opinion of management, the carrying amount of the investments exceeds
       its recoverable amount.

    (k)Interests in associates
       An associate is a company, not being a subsidiary, in which the Group
       exercises significant influence over its management. Significant
       influence is the power to participate in the financial and operating
       policy decisions of the investee but is not control over those policies.

       Investments in associates are accounted for using the equity method from
       the date that significant influence commences until the date that
       significant influence ceases.




2   PRINCIPAL ACCOUNTING POLICIES (Continued)

    (l)Jointly controlled entities
       A jointly controlled entity is an entity over which the Group can
       exercise joint control with other venturers. Joint control is the
       contractually agreed sharing of control over an economic activity.

       The Group's interests in jointly controlled entities are accounted for
       on a proportionate consolidation basis. Under this method, the Group
       combines its proportionate share of the jointly controlled entity's
       turnover and expenses with each major turnover and expenses caption of
       the Group's income statement and combines its proportionate share of the
       jointly controlled entity's assets and liabilities with each major asset
       and liability caption of the Group's balance sheet.

    (m)Provisions
       A provision is recognised in the balance sheet when the Group has a
       legal or constructive obligation as a result of a past event, and it is
       probable that an outflow of economic benefits will be required to settle
       the obligation.

    (n)Revenue recognition
       Revenues associated with the sale of crude oil, natural gas, petroleum
       and chemical products and ancillary materials are recorded when the
       customer accepts the goods and the significant risks and rewards of
       ownership and title have been transferred to the buyer. Revenue from the
       rendering of services is recognised in the income statement upon
       performance of the services. No revenue is recognised if there are
       significant uncertainties regarding recovery of the consideration due,
       the possible return of goods, or when the amount of revenue and the
       costs incurred or to be incurred in respect of the transaction cannot be
       measured reliably.

       Interest income is recognised on a time apportioned basis that takes
       into account the effective yield on the asset.

    (o)Borrowing costs
       Borrowing costs are expensed in the income statement in the period in
       which they are incurred, except to the extent that they are capitalised
       as being attributable to the construction of an asset which necessarily
       takes a period of time to get ready for its intended use.

    (p)Repairs and maintenance expenditure
       Repairs and maintenance expenditure, including cost of major overhaul,
       is expensed as incurred.

    (q)Environmental expenditures
       Environmental expenditures that relate to current ongoing operations or
       to conditions caused by past operations are expensed as incurred.

       Liabilities related to future remediation costs are recorded when
       environmental assessments and/or cleanups are probable and the costs can
       be reasonably estimated. As facts concerning environmental contingencies
       become known to the Group, the Group reassesses its position both with
       respect to accrued liabilities and other potential exposures.

    (r)Research and development costs
       Research and development costs are recognised as expenses in the period
       in which they are incurred.

    (s)Operating leases
       Operating lease payments are charged to the income statement on a
       straight-line basis over the period of the respective leases.

    (t)Retirement benefits
       The contributions payable under the Group's retirement plans are charged
       to the income statement as incurred and according to the contribution
       determined by the plans. Further information is set out in Note 29.

    (u)Impairment loss
       The carrying amounts of long-lived assets are reviewed periodically in
       order to assess whether the recoverable amounts have declined below the
       carrying amounts. These assets are tested for impairment whenever events
       or changes in circumstances indicate that their recorded carrying
       amounts may not be recoverable. When such a decline has occurred, the
       carrying amount is reduced to the recoverable amount. The recoverable
       amount is the greater of the net selling price and the value in use. In
       determining the value in use, expected future cash flows generated by
       the asset are discounted to their present value. The amount of the
       reduction is recognised as an expense in the income statement unless the
       asset is carried at revalued amount for which an impairment loss is
       recognised directly against any related revaluation reserve to the
       extent that the impairment loss does not exceed the amount held in the
       revaluation reserve for that same asset.

       The Group assesses at each balance sheet date whether there is any
       indication that an impairment loss recognised for an asset in prior
       years may no longer exist. An impairment loss is reversed if there has
       been a favourable change in the estimates used to determine the
       recoverable amount. A subsequent increase in the recoverable amount of
       an asset, when the circumstances and events that led to the write-down
       or write-off cease to exist, is recognised as income unless the asset is
       carried at revalued amount. Reversal of an impairment loss on a revalued
       asset is credited to the revaluation reserve except for impairment loss
       which was previously recognised as an expense in the income statement; a
       reversal of such impairment loss is recognised as income. The reversal
       is reduced by the amount that would have been recognised as depreciation
       had the write-down or write-off not occurred.




2   PRINCIPAL ACCOUNTING POLICIES (Continued)

    (v)Income tax
       Income tax comprises current and deferred tax. Current tax is calculated
       on taxable income by applying the applicable tax rates. Deferred tax is
       provided using the balance sheet liability method on all temporary
       differences between the carrying amounts of assets and liabilities for
       financial reporting purposes and the amounts used for taxation purposes.
       Deferred tax is calculated on the basis of the enacted tax rates that
       are expected to apply in the period when the asset is realised or the
       liability is settled.

       The tax value of losses expected to be available for utilisation against
       future taxable income is set off against the deferred tax liability
       within the same legal tax unit and jurisdiction to the extent
       appropriate, and is not available for set-off against the taxable profit
       of another legal tax unit. Deferred tax assets are reduced to the extent
       that it is no longer probable that the related tax benefit will be
       realised.

    (w)Dividends
       Dividends are recognised as a liability in the period in which they are
declared.

    (x)Segmental reporting
       A business segment is a distinguishable component of the Group that is
       engaged in providing products or services and is subject to risks and
       rewards that are different from those of other segments.

3   TURNOVER
    Turnover represents revenue from the sales of crude oil, natural gas,
    petroleum and chemical products, net of value-added tax.

       In accordance with IAS 36, the carrying amounts of impaired oil and gas properties and long-lived assets are written down
       to a recoverable value.

       Impairment losses recognised on long-lived assets of the chemicals segment of RMB 2,140 million (2003: RMB nil) for the
       six-month period ended 30 June 2004 primarily relate to certain chemical production facilities that are held for use. The
       carrying values of these facilities were written down to their recoverable values which were based on the asset held for
       use model using the present value of estimated future cash flows. An amount of RMB 1,701 million was charged to the
       income statement with the remaining amount of RMB 439 million recognised directly against the related revaluation reserve
       in respect of those assets that were carried at revalued amount. The primary factor resulting in the impairment losses of
       the chemicals segment was due to higher operating and production costs caused by the increase in the prices of raw
       materials during the period.

       Impairment losses recognised on long-lived assets of the marketing and distribution segment of RMB 623 million (2003: RMB
       nil) for the six-month period ended 30 June 2004 primarily relate to certain service stations that were closed during the
       period. In measuring the amounts of impairment charges, the carrying amounts of these assets were compared to the present
       value of the expected future cash flows of the assets, as well as information about sales and purchases of similar
       properties in the same geographic area.

       The factors resulting in the exploration and production ("E&P") segment impairment losses of RMB 269 million for the
       six-month period ended 30 June 2003 were unsuccessful development drilling and high operating and development costs for
       certain oil fields. The carrying values of these E&P properties were written down to a recoverable value which was
       determined based on the present values of the expected future cash flows of the assets. The oil and gas pricing was a
       factor used in the determination of the present values of the expected future cash flows of the assets and had an impact
       on the recognition of the asset impairment.

    A valuation allowance on deferred tax assets is recorded if it is more
    likely than not that some portion or all of the deferred tax assets will
    not be realised through the recovery of taxes previously paid and/or future
    taxable income. The allowance is subject to ongoing adjustments based on
    changes in circumstances that affect the Group's assessment of the
    realisability of the deferred tax assets. The Group has reviewed its
    deferred tax assets at the balance sheet date. Based on this review,
    valuation allowances of RMB 360 million (2003: RMB 66 million) were
    provided for the six-month period ended 30 June 2004. The Group determined
    the valuation allowance based on management's assessment of the probability
    that taxable profit will be available over the period which the deferred
    tax assets can be realised or utilised. In assessing the probability, both
    positive and negative evidence was considered, including whether it is more
    likely than not that the operations will have future taxable profits over
    the periods which the deferred tax assets are deductible or utilised and
    whether the tax losses result from identifiable causes which are unlikely
    to recur. Based on this assessment, a valuation allowance was provided to
    reduce the deferred tax asset to the amount that is more likely than not to
    be realised.

       assumed by the Company in the Reorganisation, no other liabilities were
       assumed by the Company, and the Company is not jointly and severally
       liable for other debts and obligations incurred by Sinopec Group Company
       prior to the Reorganisation.

    (b)At 30 June 2004 and 31 December 2003, guarantees given to banks in
       respect of banking facilities granted to the parties below were as
       follows:



                                                                                                At 30 June    At 31 December
                                                                                                      2004              2003
                                                                                              RMB millions      RMB millions
                                                                                                         

       Associates                                                                                    4,897             4,955
-----------------------------------------------------------------------------------------------------------------------------


    The Company monitors the conditions that are subject to the guarantees to
    identify whether it is probable that a loss has occurred, and recognise any
    such losses under guarantees when those losses are estimable. At 30 June
    2004 and 31 December 2003, it is not probable that the Company will be
    required to make payments under the guarantees. Thus no liability has been
    accrued for a loss related to the Company's obligation under these
    guarantee arrangements.

    Environmental contingencies
    To date, the Group has not incurred any significant expenditures for
    environmental remediation, is currently not involved in any environmental
    remediation, and has not accrued any amounts for environmental remediation
    relating to its operations. Under existing legislation, management believes
    that there are no probable liabilities that will have a material adverse
    effect on the financial position or operating results of the Group. The PRC
    government, however, has moved, and may move further towards more rigorous
    enforcement of applicable laws, and towards the adoption of more stringent
    environmental standards. Environmental liabilities are subject to
    considerable uncertainties which affect the Group's ability to estimate the
    ultimate cost of remediation efforts. These uncertainties include i) the
    exact nature and extent of the contamination at various sites including,
    but not limited to refineries, oil fields, service stations, terminals and
    land development areas, whether operating, closed or sold, ii) the extent
    of required cleanup efforts, iii) varying costs of alternative remediation
    strategies, iv) changes in environmental remediation requirements, and v)
    the identification of new remediation sites. The amount of such future cost
    is indeterminable due to such factors as the unknown magnitude of possible
    contamination and the unknown timing and extent of the corrective actions
    that may be required. Accordingly, the outcome of environmental liabilities
    under proposed or future environmental legislation cannot reasonably be
    estimated at present, and could be material. The Group paid normal routine
    pollutant discharge fees of approximately RMB 113 million for the six-month
    period ended 30 June 2004 (2003: RMB 85 million).

    Legal contingencies
    The Group is a defendant in certain lawsuits as well as the named party in
    other proceedings arising in the ordinary course of business. While the
    outcomes of such contingencies, lawsuits or other proceedings cannot be
    determined at present, management believes that any resulting liabilities
    will not have a material adverse effect on the financial position or
    operating results of the Group.

28  RELATED PARTY TRANSACTIONS
    Companies are considered to be related if one company has the ability,
    directly or indirectly, to control the other company or exercise
    significant influence over the other company in making financial and
    operating decisions. Companies are also considered to be related if they
    are subject to common control or common significant influence.

    The Group is part of a larger group of companies under Sinopec Group
    Company and has significant transactions and relationships with the Sinopec
    Group Company and fellow subsidiaries. Because of these relationships, it
    is possible that the terms of these transactions are not the same as those
    that would result from transactions among wholly unrelated parties. Sinopec
    Group Company itself is owned by the PRC government. There are also many
    other enterprises directly or indirectly owned or controlled by the PRC
    government ("state-owned enterprises"). Under IFRS, state-owned
    enterprises, other than Sinopec Group Company and fellow subsidiaries, are
    not considered related parties. Related parties refer to enterprises over
    which Sinopec Group Company is able to exercise significant influence.

    The Group conducts business with state-owned enterprises. Furthermore, the
    PRC government itself represents a significant customer of the Group both
    directly through its numerous authorities and indirectly through its
    numerous affiliates and other organisations. Sales of certain products to
    PRC government authorities and affiliates and other state-owned enterprises
    may be at regulated prices, which differ from market prices. The Group
    considers that these sales are activities in the ordinary course of
    business in the PRC and has not disclosed such sales as related party
    transactions.

28  RELATED PARTY TRANSACTIONS (Continued)
    In connection with the Reorganisation, the Company and Sinopec Group
    Company entered into a number of agreements under which 1) Sinopec Group
    Company will provide goods and products and a range of ancillary, social
    and supporting services to the Group and 2) the Group will sell certain
    goods to Sinopec Group Company. The terms of these agreements are
    summarised as follows:

    (a)The Company has entered into a non-exclusive Agreement for Mutual
       Provision of Products and Ancillary Services ("Mutual Provision
       Agreement") with Sinopec Group Company effective from 1 January 2000 in
       which Sinopec Group Company has agreed to provide the Group with certain
       ancillary production services, construction services, information
       advisory services, supply services and other services and products.
       While each of Sinopec Group Company and the Company is permitted to
       terminate the Mutual Provision Agreement upon at least six months
       notice, Sinopec Group Company has agreed not to terminate the agreement
       if the Group is unable to obtain comparable services from a third party.
       The pricing policy for these services and products provided by Sinopec
       Group Company to the Group is as follows:

       o   the government-prescribed price;

       o   where there is no government-prescribed price, the
           government-guidance price;

       o   where there is neither a government-prescribed price nor a
           government-guidance price, the market price; or

       o   where none of the above is applicable, the price to be agreed
           between the parties, which shall be based on a reasonable cost
           incurred in providing such services plus a profit margin not
           exceeding 6%.

    (b)The Company has entered into a non-exclusive Agreement for Provision of
       Cultural and Educational, Health Care and Community Services with
       Sinopec Group Company effective from 1 January 2000 in which Sinopec
       Group Company has agreed to provide the Group with certain cultural,
       educational, health care and community services on the same pricing
       terms and termination conditions as agreed to in the above Mutual
       Provision Agreement.

    (c)The Company has entered into a series of lease agreements with Sinopec
       Group Company to lease certain land and buildings at a rental of
       approximately RMB 2,447 million and RMB 482 million, respectively, per
       annum. The Company and Sinopec Group Company can renegotiate the rental
       amount every three years for land and every year for buildings, such
       amount not to exceed the market price as determined by an independent
       third party. The Group has the option to terminate these leases upon six
       months notice to Sinopec Group Company.

    (d)The Company has entered into agreements with Sinopec Group Company
       effective from 1 January 2000 under which the Group has been granted the
       right to use certain trademarks, patents, technology and computer
       software developed by Sinopec Group Company. The Group will reimburse
       Sinopec Group Company for fees required to maintain the validity of
       these licenses.

    (e)The Company has entered into agency agreements effective from 1 January
       2000 with certain entities owned by Sinopec Group Company under which
       the Group acts as a sole agent in respect of the sale of all the
       products of these entities. In exchange for the Group's sales agency
       services, Sinopec Group Company has agreed to pay the Group a commission
       of between 0.2% and 1.0% of actual sales receipts depending on the
       products and to reimburse the Group for reasonable costs incurred in the
       capacity as its sales agent.

    (f)The Company has entered into a service stations franchise agreement with
       Sinopec Group Company effective from 1 January 2000 under which its
       service stations and retail stores would exclusively sell the refined
       products supplied by the Group.

29  EMPLOYEE BENEFITS PLAN
    As stipulated by the regulations of the PRC, the Group participates in
    various defined contribution retirement plans organised by municipal and
    provincial governments for its staff. The Group is required to make
    contributions to the retirement plans at rates ranging from 17.0% to 30.0%
    of the salaries, bonuses and certain allowances of its staff. A member of
    the plan is entitled to a pension equal to a fixed proportion of the salary
    prevailing at his or her retirement date. The Group has no other material
    obligation for the payment of pension benefits associated with these plans
    beyond the annual contributions described above. The Group's contributions
    for the six-month period ended 30 June 2004 were RMB 959 million (2003: RMB
    896 million).

    The Company implemented a plan of share appreciation rights for members of
    its senior management in order to provide further incentives to these
    employees. Under this plan, share appreciation rights were granted in units
    with each unit representing one H share. No shares will be issued under the
    share appreciation rights plan.

    Under the plan, all share appreciation rights have an exercise period of
    five years. A recipient of share appreciation rights may not exercise the
    rights in the first 3 years after the date of grant. As at each of the
    third, fourth and fifth anniversary of the date of grant, the total number
    of share appreciation rights exercisable may not in aggregate exceed 30%,
    70% and 100%, respectively, of the total share appreciation rights granted
    to such person.

    During 2003, the Company granted 258.6 million share appreciation right
    units to eligible employees accordingly.

    The exercise price of share appreciation rights initially granted is the
    initial public offering price of the Company's H shares. Upon exercise of
    the share appreciation rights, a recipient will receive, subject to any
    applicable withholding tax, a cash payment in RMB, translated from the Hong
    Kong dollar amount equal to the product of the number of share appreciation
    rights exercised and the difference between the exercise price and average
    market price of the Company's H shares for the exercise period based on the
    applicable exchange rate between RMB and Hong Kong dollar at the date of
    the exercise.

    The Company recognises compensation expense of the share appreciation
    rights over the applicable vesting period. For the six-month period ended
    30 June 2004, compensation expense recognised was RMB 144 million.



30  SEGMENTAL REPORTING
    The Group has five operating segments as follows:

    (i)Exploration and production, which explores and develops oil fields,
       produces crude oil and natural gas and sells such products to the
       refining segment of the Group and external customers.

    (ii) Refining, which processes and purifies crude oil, which is sourced
       from the exploration and production segment of the Group and external
       suppliers, and manufactures and sells petroleum products to the
       chemicals and marketing and distribution segments of the Group and
       external customers.

    (iii)Marketing and distribution, which owns and operates oil depots and
       service stations in the PRC, and distributes and sells refined petroleum
       products (mainly gasoline and diesel) in the PRC through wholesale and
       retail sales networks.

    (iv) Chemicals, which manufactures and sells petrochemical products,
       derivative petrochemical products and other chemical products mainly to
       external customers.

    (v)Corporate and others, which largely comprise the trading activities of
       the import and export companies of the Group and research and
       development undertaken by other subsidiaries.

    The segments were determined primarily because the Group manages its
    exploration and production; refining; marketing and distribution;
    chemicals; and corporate and others businesses separately. The reportable
    segments are each managed separately because they manufacture and/or
    distribute distinct products with different production processes and due to
    their distinct operating and gross margin characteristics. In view of the
    fact that the Company and its subsidiaries operate mainly in the PRC, no
    geographical segment information is presented.

    The Group evaluates the performance and allocates resources to its
    operating segments on an operating income basis, without considering the
    effects of finance costs or investment income. The accounting policies of
    the Group's segments are the same as those described in the principal
    accounting policies (see Note 2). Corporate administrative costs and assets
    are not allocated to the operating segments; instead, operating segments
    are billed for direct corporate services. Inter-segment transfer pricing is
    based on cost plus an appropriate margin, as specified by the Group's
    policy.

    Reportable information on the Group's business segments is as follows:



                                                                                                       Six-month periods

    Except for Sinopec Kantons Holdings Limited, which is incorporated in
    Bermuda, all of the above principal subsidiaries are incorporated in the
    PRC.

    (i) The Group consolidated the results of the entity because the Group
        controlled the board of this entity and had the power to govern its
        financial and operating policies.



32  FINANCIAL INSTRUMENTS
    Financial assets of the Group include cash and cash equivalents, time
    deposits with financial institutions, investments, trade accounts
    receivable, bills receivable, amounts due from Sinopec Group Company and
    fellow subsidiaries, advances to third parties, amounts due from
    associates, and other receivables. Financial liabilities of the Group
    include bank and other loans, loans from Sinopec Group Company and fellow
    subsidiaries, trade accounts payable, bills payable, amounts due to Sinopec
    Group Company and fellow subsidiaries, receipts in advance, and advances
    from third parties. The Group has no derivative instruments that are
    designated and qualified as hedging instruments at 30 June 2004 and 31
    December 2003.

    Credit risk
    The carrying amounts of cash and cash equivalents, time deposits with
    financial institutions, trade accounts and bills receivables, and other
    current assets, except for prepayments and deposits, represent the Group's
    maximum exposure to credit risk in relation to financial assets.

    The majority of the Group's trade accounts receivable relate to sales of
    petroleum and chemical products to related parties and third parties
    operating in the petroleum and chemical industries. The Group performs
    ongoing credit evaluations of its customers' financial condition and
    generally does not require collateral on trade accounts receivable. The
    Group maintains an allowance for doubtful accounts and actual losses have
    been within management's expectations. No single customer accounted for
    greater than 10% of total revenues.

    No other financial assets carry a significant exposure to credit risk.

    Currency risk
    Substantially all of the revenue-generating operations of the Group are
    transacted in Renminbi, which is not fully convertible into foreign
    currencies. On 1 January 1994, the PRC government abolished the dual rate
    system and introduced a single rate of exchange as quoted by the People's
    Bank of China. However, the unification of the exchange rate does not imply
    convertibility of Renminbi into United States dollars or other foreign
    currencies. All foreign exchange transactions continue to take place either
    through the People's Bank of China or other banks authorised to buy and
    sell foreign currencies at the exchange rates quoted by the People's Bank
    of China. Approval of foreign currency payments by the People's Bank of
    China or other institutions requires submitting a payment application form
    together with suppliers' invoices, shipping documents and signed contracts.

    Interest rate risk
    The interest rates and terms of repayment of short-term and long-term debts
    of the Group are disclosed in Note 23.

    The disclosures of the fair value estimates, methods and assumptions, set
    forth below for the Group's financial instruments, are made to comply with
    the requirements of IAS 32 and IAS 39 and should be read in conjunction
    with the Group's consolidated financial statements and related notes. The
    estimated fair value amounts have been determined by the Group using market
    information and valuation methodologies considered appropriate. However,
    considerable judgment is required to interpret market data to develop the
    estimates of fair value. Accordingly, the estimates presented herein are
    not necessarily indicative of the amounts the Group could realise in a
    current market exchange. The use of different market assumptions and/or
    estimation methodologies may have a material effect on the estimated fair
    value amounts.

    The Group has not developed an internal valuation model necessary to make
    the estimate of the fair value of loans from Sinopec Group Company and
    fellow subsidiaries as it is not considered practicable to estimate their
    fair value because the cost of obtaining discount and borrowing rates for
    comparable borrowings would be excessive based on the Reorganisation of the
    Group, its existing capital structure, and the terms of the borrowings.

    The following table presents the carrying amount and fair value of the
    Group's long-term indebtedness other than loans from Sinopec Group Company
    and fellow subsidiaries at 30 June 2004 and 31 December 2003:




                                                                                                At 30 June    At 31 December
                                                                                                      2004              2003
                                                                                              RMB millions      RMB millions
                                                                                                         
    Carrying amount                                                                                 57,967            49,600

    Fair value                                                                                      58,082            49,698
-----------------------------------------------------------------------------------------------------------------------------


    The fair value of long-term indebtedness is estimated by discounting future
    cash flows thereon using current market interest rates offered to the Group
    for debts with substantially the same characteristics and maturities.

    Investments in unlisted equity securities have no quoted market prices in
    the PRC. Accordingly, a reasonable estimate of fair value could not be made
    without incurring excessive costs.

    The fair values of all other financial instruments approximate their
    carrying amounts due to the nature or short-term maturity of these
    instruments.

33  ULTIMATE HOLDING COMPANY
    The directors consider the ultimate holding company of the Group at 30 June
    2004 to be Sinopec Group Company, a state-owned enterprise established in
    the PRC.



(C)  DIFFERENCES BETWEEN FINANCIAL STATEMENTS PREPARED UNDER THE PRC ACCOUNTING
     RULES AND REGULATIONS AND IFRS


Other than the differences in the classifications of certain financial
statements captions and the accounting for the items described below, there are
no material differences between the Group's financial statements prepared under
the PRC Accounting Rules and Regulations and IFRS. The major differences are:

(i) Disposal of oil and gas properties
    Under the PRC Accounting Rules and Regulations, gains and losses arising
    from the retirement or disposal of an individual item of oil and gas
    properties are recognised as income or expense in the income statement and
    are measured as the difference between the estimated net disposal proceeds
    and the carrying amount of the asset.

    Under IFRS, gains and losses on the retirement or disposal of an individual
    item of proved oil and gas properties are not recognised unless the
    retirement or disposal encompasses an entire property. The costs of the
    asset abandoned or retired are charged to accumulated depreciation with the
    proceeds received on disposals credited to the carrying amounts of oil and
    gas properties.

(ii) Impairment losses on revalued assets
    Under the PRC Accounting Rules and Regulations, impairment losses on fixed
    assets are recognised as expense in the income statement. Under IFRS,
    impairment loss on a revalued asset is recognised directly against any
    related revaluation reserve to the extent that the impairment loss does not
    exceed the amount held in the revaluation reserve for that same asset.

(iii) Depreciation of oil and gas properties
    Under the PRC Accounting Rules and Regulations, oil and gas properties are
    depreciated on a straight-line basis. Under IFRS, oil and gas properties
    are depreciated on the unit of production method.

(iv) Capitalisation of general borrowing costs
    Under the PRC Accounting Rules and Regulations, only borrowing costs on
    funds that are specifically borrowed for construction are capitalised as
    part of the cost of fixed assets. Under IFRS, to the extent that funds are
    borrowed generally and used for the purpose of obtaining a qualifying
    asset, the borrowing costs should be capitalised as part of the cost of
    that asset.

(v) Acquisition of Sinopec National Star, Sinopec Maoming, Xi'an Petrochemical
    and Tahe Petrochemical Under the PRC Accounting Rules and Regulations, the
    acquisition of Sinopec National Star, Sinopec Maoming, Xi'an Petrochemical
    and Tahe Petrochemical (the "Acquisitions") are accounted for by the
    acquisition method. Under the acquisition method, the income of an
    acquiring enterprise includes the operations of the acquired enterprise
    subsequent to the acquisition. The difference between the cost of acquiring
    Sinopec National Star and the fair value of the net assets acquired is
    capitalised as an exploration and production right, which is amortised over
    27 years. The costs of acquiring Sinopec Maoming, Xi'an Petrochemical and
    Tahe Petrochemical approximated the fair value of the net assets acquired.

    Under IFRS, as the Group, Sinopec National Star, Sinopec Maoming, Xi'an
    Petrochemical and Tahe Petrochemical are under the common control of
    Sinopec Group Company, the Acquisitions are considered "combination of
    entities under common control" which are accounted in a manner similar to a
    pooling-of-interests ("as-if pooling-of-interests accounting").
    Accordingly, the assets and liabilities of Sinopec National Star, Sinopec
    Maoming, Xi'an Petrochemical and Tahe Petrochemical acquired have been
    accounted for at historical cost and the financial statements of the Group
    for periods prior to the Acquisitions have been restated to include the
    financial condition and results of operations of Sinopec National Star,
    Sinopec Maoming, Xi'an Petrochemical and Tahe Petrochemical on a combined
    basis. The considerations paid by the Group are treated as an equity
    transaction.

(vi) Revaluation of land use rights
    Under the PRC Accounting Rules and Regulations, land use rights are carried
    at revalued amount. Under IFRS, land use rights are carried at historical
    cost less amortisation. Accordingly, the surplus on the revaluation of land
    use rights, credited to revaluation reserve, was eliminated.

(vii) Unrecognised losses of subsidiaries
    Under the PRC Accounting Rules and Regulations, the results of subsidiaries
    are included in the Group's consolidated income statement to the extent
    that the subsidiaries' accumulated losses do not result in their carrying
    amount being reduced to zero, without the effect of minority interests.
    Further losses are debited to a separate reserve in the shareholders'
    funds.

    Under IFRS, the results of subsidiaries are included in the Group's
    consolidated income statement from the date that control effectively
    commences until the date that control effectively ceases.

(viii) Pre-operating expenditures
    Under the PRC Accounting Rules and Regulations, expenditures incurred
    during the start-up period are aggregated in long-term deferred expenses
    and charged to the income statement when operations commence. Under IFRS,
    expenditures on start-up activities are recognised as an expense when they
    are incurred.

(ix) Impairment losses on long-lived assets
    Under the PRC Accounting Rules and Regulations and IFRS, impairment charges
    are recognised when the carrying value of long-lived assets exceeds the
    higher of their net selling price and the value in use which incorporates
    discounting the asset's estimated future cash flows. Due to the difference
    in the depreciation method of oil and gas properties discussed in (iii)
    above, the provision for impairment losses and reversal of impairment loss
    under the PRC Accounting Rules and Regulations are different from the
    amounts recorded under IFRS.



(x) Government grxants
    Under the PRC Accounting Rules and Regulations, government grants should be
    credited to capital reserve. Under IFRS, government grants relating to the
    purchase of equipment used for technology improvements are initially
    recorded as long term liabilities and are offset against the cost of assets
    to which the grants related when construction commences. Upon transfer to
    property, plant and equipment, the grants are recognised as an income over
    the useful life of the property, plant and equipment by way of reduced
    depreciation charge.

    Effects of major differences between the PRC Accounting Rules and
    Regulations and IFRS on net profit are analysed as follows:



                                                                                              Six-month periods ended 30 June

(D) SUPPLEMENTAL INFORMATION FOR NORTH AMERICAN SHAREHOLDERS


The Group's accounting policies conform with IFRS which differ in certain
significant respects from accounting principles generally accepted in the
United States of America ("US GAAP"). Information relating to the nature and
effect of such differences are set out below. The US GAAP reconciliation
presented below is included as supplemental information, is not required as
part of the basic financial statements and does not include differences related
to classification, display or disclosures. Such information has not been
subject to independent audit or review.

(a) Foreign exchange gains and losses
    In accordance with IFRS, foreign exchange differences on funds borrowed for
    construction are capitalised as property, plant and equipment to the extent
    that they are regarded as an adjustment to interest costs during the
    construction period. Under US GAAP, all foreign exchange gains and losses
    on foreign currency debts are included in current earnings. Accordingly,
    the US GAAP adjustments represent the amortisation effect of such
    originating adjustments described above.

(b) Capitalisation of property, plant and equipment
    In the periods prior to those presented herein, certain adjustments arose
    between IFRS and US GAAP with regard to the capitalisation of interest and
    pre-production results under IFRS that were reversed and expensed under US
    GAAP. For the periods presented herein, there were no adjustments related
    to the capitalisation of interest and pre-production results. Accordingly,
    the US GAAP adjustments represent the amortisation effect of such
    originating adjustments described above.

(c) Revaluation of property, plant and equipment As required by the relevant
    PRC regulations with respect to the Reorganisation, the property, plant and
    equipment of the Group were revalued at 30 September 1999. In addition, the
    property, plant and equipment of Sinopec National Star, Sinopec Maoming and
    Refining Assets were revalued at 31 December 2000, 30 June 2003 and 31
    October 2003 respectively in connection with the Acquisitions. Under IFRS,
    such revaluations result in an increase in shareholders' funds with respect
    to the increase in carrying amount of certain property, plant and equipment
    above their historical cost bases and a charge to income with respect to
    the reduction in carrying amount of certain property, plant and equipment
    below their historical cost bases.

    Under US GAAP, property, plant and equipment are stated at their historical
    cost less accumulated depreciation. However, as a result of the tax
    deductibility of the net revaluation surplus, a deferred tax asset related
    to the reversal of the revaluation surplus is created under US GAAP with a
    corresponding increase in shareholders' funds.

    In addition, under IFRS, on disposal of a revalued asset, the related
    revaluation surplus is transferred from the revaluation reserve to retained
    earnings. Under US GAAP, the gain and loss on disposal of an asset is
    determined with reference to the asset's historical carrying amount and
    included in current earnings.

(d) Exchange of assets
    During 2002, the Company and Sinopec Group Company entered into an asset
    swap transaction. Under IFRS, the cost of property, plant and equipment
    acquired in an exchange for a dissimilar item of property, plant and
    equipment is measured at fair value. Under US GAAP, as the exchange of
    assets was between entities under common control, the assets received from
    Sinopec Group Company are measured at historical cost. The difference
    between the historical cost of the net assets transferred and the net
    assets received is accounted for as an equity transaction. Accordingly, the
    US GAAP adjustments represent the amortisation effect of such originating
    adjustments described above.

(e) Impairment of long-lived assets
    Under IFRS, impairment charges are recognised when a long-lived asset's
    carrying amount exceeds the higher of an asset's net selling price and
    value in use, which incorporates discounting the asset's estimated future
    cash flows.

    Under US GAAP, determination of the recoverability of a long-lived asset is
    based on an estimate of undiscounted future cash flows resulting from the
    use of the asset and its eventual disposition. If the sum of the expected
    future cash flows is less than the carrying amount of the asset, an
    impairment loss is recognised. Measurement of an impairment loss for a
    long-lived asset is based on the fair value of the asset.

    In addition, under IFRS, a subsequent increase in the recoverable amount of
    an asset is reversed to the consolidated income statement to the extent
    that an impairment loss on the same asset was previously recognised as an
    expense when the circumstances and events that led to the write-down or
    write-off cease to exist. The reversal is reduced by the amount that would
    have been recognised as depreciation had the write-off not occurred. Under
    US GAAP, an impairment loss establishes a new cost basis for the impaired
    asset and the new cost basis should not be adjusted subsequently other than
    for further impairment losses.

    The US GAAP adjustment represents the effect of reversing the recovery of
    previous impairment charges recorded under IFRS.



(f) Capitalised interest on investment in associates
    Under IFRS, investment accounted for by the equity method is not considered
    a qualifying asset for which interest is capitalised. Under US GAAP, an
    investment accounted for by the equity method while the investee has
    activities in progress necessary to commence its planned principal
    operations, provided that the investee's activities include the use of
    funds to acquire qualifying assets for its operations, is a qualifying
    asset for which interest is capitalised.

(g) Goodwill amortisation
    Under IFRS, goodwill and negative goodwill are amortised on a systematic
    basis over their useful lives.

    Under US GAAP, with reference to Statement of Financial Accounting
    Standards No.142, "Goodwill and Other Intangible Assets" ("SFAS No.142"),
    goodwill is no longer amortised beginning 1 January 2002. Instead, goodwill
    is reviewed for impairment upon adoption of SFAS No.142 and annually
    thereafter.

    The effect on profit attributable to shareholders of significant
    differences between IFRS and US GAAP is as follows:
