To the Shareholders

Dear Sir or Madam,

                            REVISION OF EXISTING CAPS
                                       AND
                           AMENDMENTS TO THE ARTICLES

1.   THE ACQUISITION

     On 23 August 2006, the Board announced that CNPC E&D, a subsidiary of
PetroChina and a 50 : 50 joint venture between PetroChina and CNODC, entered
into the Acquisition Agreement through the Acquirer (a wholly owned subsidiary
of CNPC E&D) with the Vendor (a wholly owned subsidiary of CNODC), for the
acquisition by the Acquirer of CNODC's entire interest in PetroKazakhstan,
representing 67% of the issued share capital of PetroKazakhstan.


                                       -4-



                              LETTER FROM THE BOARD

     The Board believes that the Acquisition represents an important opportunity
for PetroChina to further enhance its overseas working interests of oil and gas
reserve, to expand PeroChina's overseas exploration and production assets in a
strategically important region, to derive synergies from the Kazakhstan-China
Pipeline, the Dushanzi Refinery and CNPC E&D's existing Kazakhstan exploration
and production operations and to further improve PetroChina's financial
performance.

     CNODC is wholly owned by CNPC, the controlling shareholder of PetroChina.
As at the date of this circular, CNPC holds approximately 88.21% of the issued
share capital of PetroChina. Pursuant to the Listing Rules, CNODC and the Vendor
are connected persons of PetroChina. CNPC E&D is a connected person of
PetroChina pursuant to Listing Rule 14A.11(5). Upon the completion of the
Acquisition, PetroChina will, through CNPC E&D, hold 67% of PetroKazakhstan.
PetroKazakhstan will therefore become a non-wholly owned subsidiary of CNPC E&D
and PetroChina and a connected person of PetroChina pursuant to Rule 14A.11(6)
of the Listing Rules.

     The Acquisition constitutes a connected transaction of PetroChina under the
Listing Rules. As the relevant percentage ratios involved in the Acquisition are
more than 0.1% but less than 2.5% for the Group, the Acquisition is only subject
to reporting and announcement requirements and exempted from the independent
shareholders' approval requirement under Rule 14A.32 of the Listing Rules.

     Further details regarding the Acquisition, the Acquisition Agreement and
PetroKazakhstan were set out in the Announcement.

2.   REVISION OF EXISTING CAPS AND LISTING RULES IMPLICATIONS

     The Announcement also announced that PetroChina proposes to revise the
Existing Caps under the Amended Comprehensive Agreement and the CRMSC Products
and Services Agreement as previously approved by the Independent Shareholders
(or by the Shareholders in respect of the Existing Caps for the CRMSC
Transactions) on 8 November 2005. The Proposed Caps, for the three-year period
from 1 January 2006 to 31 December 2008, are the result of:

     -    continuing connected transactions arising as a result of the
          completion of the Acquisition, which will fall within the scope of the
          Amended Comprehensive Agreement; and

     -    changes to PetroChina's production and operational environment that
          are expected to have an impact on the Existing Caps under the Amended
          Comprehensive Agreement and the CRMSC Products and Services Agreement,
          as explained in detail in this circular.

     The Proposed Caps are subject to reporting, announcement and Independent
Shareholders' approval (or Shareholders' approval in respect of the Proposed
Caps for the CRMSC Transactions) requirements under the Listing Rules.

     An Independent Board Committee has been appointed by the Board to consider
the Proposed Caps. ICEA Capital Limited has been retained as the Independent
Financial Adviser to advise the Independent Board Committee as to whether the
Proposed Caps are fair and reasonable so far as the Shareholders are concerned.

                              LETTER FROM THE BOARD

3.   THE AMENDED COMPREHENSIVE AGREEMENT

     The Amended Comprehensive Agreement was entered into by and between CNPC
and PetroChina on 10 March 2001, which was further amended on 9 June 2005 and 1
September 2005 respectively. The Amended Comprehensive Agreement is valid for
three years, commencing from 1 January 2006. Detailed information about the
terms and conditions of the Amended Comprehensive Agreement, including but not
limited to general principles, price and terms, price determination,
coordination of annual demand of products and services, rights and obligations,
term and termination and the annual caps in respect of the transactions under
the Amended Comprehensive Agreement were disclosed in the circular to the
Shareholders dated 22 September 2005 and were approved by the Independent
Shareholders at the extraordinary general meeting held on 8 November 2005.

     The Amended Comprehensive Agreement applies to connected transactions
between the CNPC Group (including Jointly-owned Companies) and the Group.
Pursuant to the Amended Comprehensive Agreement, a Jointly-owned Company means a
company in which both PetroChina and the CNPC Group are shareholders, and where
the CNPC Group and/or its subsidiaries and/or affiliates (individually or
together) is/are entitled to exercise, or control the exercise of, 10% or more
of the voting power at any general meeting of such company.

     As explained in the Announcement, PetroKazakhstan will be equity-accounted
for in PetroChina's consolidated financial statements since PetroChina and KMG
are considered as having joint control over PetroKazakhstan. At the same time,
PetroKazakhstan will be treated as a "subsidiary" of PetroChina for the purposes
of the Listing Rules because, among other things, PetroChina will hold more than
half of the issued share capital of PetroKazakhstan. Accordingly, upon the
completion of the Acquisition, PetroKazakhstan will become a non-wholly owned
subsidiary of PetroChina. It will also become a connected person of PetroChina
pursuant to Rule 14A.11(6) of the Listing Rules as well as a Jointly-owned
Company as defined by the Amended Comprehensive Agreement. Given that
PetroKazakhstan will be a subsidiary of PetroChina held through CNPC E&D,
connected transactions involving the PetroKazakhstan Group will be treated in
the same manner as transactions involving CNPC E&D and its subsidiaries, which
were approved by the Independent Shareholders on 8 November 2005. On this basis,
PetroChina has classified connected transactions between the PetroKazakhstan
Group and the Group as transactions between the CNPC Group (including
Jointly-owned Companies) and the Group, and connected transactions between the
PetroKazakhstan Group and the CNPC Group as transactions between the Group and
the CNPC Group.

4.   THE CRMSC PRODUCTS AND SERVICES AGREEMENT

     On 1 September 2005, PetroChina entered into the CRMSC Products and
Services Agreement with CRMSC, pursuant to which PetroChina should provide CRMSC
with products and services including, among other things, refined products (such
as gasoline, diesel and other petroleum products) on an ongoing basis. CRMSC,
being a substantial shareholder of PetroChina's subsidiary, PetroChina & CRMSC
Oil Marketing, is a connected person of PetroChina pursuant to the Listing
Rules. Detailed information regarding the terms and conditions of the CRMSC
Products and Services Agreement and the annual caps in respect of CRMSC
Transactions were disclosed in the circular to the Shareholders dated 22
September 2005 and were approved by the Shareholders at the extraordinary
general meeting held on 8 November 2005.

                              LETTER FROM THE BOARD

5.   PROPOSED CAPS

     (a)  Revision due to continuing connected transactions arising as a result
          of the Acquisition

          (i)  Production services to be provided by the CNPC Group to the Group

               The Amended Comprehensive Agreement provides that the CNPC Group
          (including Jointly-owned Companies such as PetroKazakhkstan) shall
          supply crude oil, refined oil, chemical products, natural gas and
          production services (including transportation) to the Group at the
          government-prescribed price. Where there is no government-prescribed
          price but market price is available, the price shall be determined
          with reference to the market price.

               The Board has considered and proposed the following increases to
          the Existing Caps in respect of this category of transaction. Such
          increases are attributable to the Group's proposed purchase of crude
          oil from the PetroKazakhstan Group and transportation of such crude
          oil via the Kazakhstan-China Pipeline and the Western Pipeline in
          accordance with the Amended Comprehensive Agreement.



                                            Proposed increase to the
                                                  Existing Caps
                                                (RMB in millions)
                                            ------------------------

---------------------------------           ------   ------   ------
                                                     
Production services to be provided by the
   CNPC Group to the Group                  13,040   36,000   34,720


               The above proposed increases to the Existing Caps have been
          determined with reference to the following: the estimated growth in
          crude oil production and business of the PetroKazakhstan Group;
          current market prices of crude oil; potential fluctuations and
          increases in the prices of crude oil both in the international market
          and in the domestic market; the estimated annual crude oil volume to
          be purchased by the Group from the PetroKazakhstan Group; the
          transportation capacities of the Kazakhstan-China Pipeline and the
          Western Pipeline; and charges of the Kazakhstan-China Pipeline and the
          Western Pipeline for oil transportation and the potential fluctuations
          and increases in such charges. The significant increases of
          transaction amount in 2007 and 2008 are due to the increases of the
          Kazakhstan-China Pipeline's transportation capacity, which is 3.5
          million tonnes in 2006 and expected to be 10 million tonnes in 2007
          and 2008 when its construction is fully completed.

          (ii) Construction and technical services to be provided by the CNPC
               Group to the Group.

               Prior to the Acquisition, the Group has obtained construction and
          technical services from the CNPC Group. Given that the construction
          and technical services provided to the Group by the CNPC Group are of
          a high quality and on favourable pricing terms, the Group (including
          the PetroKazakhstan Group) will continue to obtain construction and
          technical services from the CNPC Group after the Acquisition.

               The Board has considered and proposed the following increases to
          the Existing Caps in respect of this category of transaction. Such
          increases are attributable to the provision of services by the CNPC
          Group to the PetroKazakhstan Group, including but not limited to
          geophysical prospecting, well drilling, logging, well testing,
          down-hole operations, oilfield surface facilities construction,
          construction design and construction supervision. This category of
          transaction will be charged on actual cost incurred basis.

                                             Proposed increases to
                                               the Existing Caps
                                               (RMB in millions)

Construction and technical services to be
   provided by the CNPC Group to the Group   1,880   1,800   1,640


               The above proposed increases to the Existing Caps have been
          determined with reference to the following: historical transaction
          price and transaction amounts for the construction and technical
          services of the PetroKazakhstan Group; and the estimated business
          growth of the PetroKazakhstan Group.

          (iii) Material supply services to be provided by the CNPC Group to the
               Group

               Prior to the Acquisition, the Group has obtained material supply
          services from the CNPC Group. Given that the material supply services
          provided by the CNPC Group to the Group is of a high quality and on
          favourable pricing terms, the Group (including the PetroKazakhstan
          Group) will continue to obtain material supply services from the CNPC
          Group after the Acquisition. This category of transaction will be
          charged on actual cost incurred basis.

               The Board has considered and proposed the following increases to
          the Existing Caps in respect of this category of transaction. Such
          increases are attributable to the provision of casing pipes, drill
          heads, drilling liquid and lubricating oil and other raw materials or
          equipment by the CNPC Group to the PetroKazakhstan Group.



                                             Proposed increases
                                               to the Existing
                                                    Caps

               The above proposed increases to the Existing Caps have been
          determined with reference to the following: historical transaction
          prices and transaction amounts in respect of material supply
          transactions of the PetroKazakhstan Group; estimated business growth
          of the PetroKazakhstan Group; and estimated changes in the volume of
          purchases by the PetroKazakhstan Group.

     (b)  Revision due to changes to PetroChina's production and operational
          environment

          (i)  Products and services to be provided by the Group to the CNPC
               Group

               The Amended Comprehensive Agreement provides that the Group shall
          provide products such as natural gas, crude oil and refined oil to the
          CNPC Group at the government-prescribed price, or where there is no
          government-prescribed price, the price shall be determined with
          reference to the market price.


                                       -8-



                              LETTER FROM THE BOARD

          The reasons for applying for increases to the Existing Caps of this
          transaction are:

          -    Natural gas

               Natural gas is sold at government-prescribed price in the PRC.
          The National Development and Reform Commission issued the Notice on
          the Reform of the Mechanism for Determining the Ex-Factory Prices of
          Natural Gas and Recent Appropriate Increase of the Ex-Factory Prices
          of Natural Gas on 23 December 2005, which made adjustments to the
          pricing mechanism and the ex-factory price of natural gas. Pursuant to
          the notice, the ex-factory price of natural gas was increased from 26
          December 2005. The notice also indicated that the PRC government would
          increase the price of natural gas in the next five years and would
          establish a system to link the price of natural gas to the price of
          substitution products including crude oil, liquefied petroleum gas and
          coal.

          -    Refined oil

               Refined oil is sold at government-prescribed price in the PRC. In
          the first half of 2006, the National Development and Reform Commission
          has issued two notices on the adjustments to the prices of refined
          oil, which increased the ex-factory prices of refined oil on 26 March
          and 24 May 2006 respectively.

          -    Crude oil

               Currently, the crude oil prices on the domestic market of the PRC
          are adjusted with reference to the crude oil prices on the
          international market. As there has been a substantial increase in the
          crude oil price on the international market recently, the increase
          with respect to domestic crude oil price has jumped well above its
          level as at 8 November 2005 when Independent Shareholders' approval
          for the Existing Caps was sought.

          -    Nephtha, solvent oil

               The Ministry of Finance and the State Administration of Taxation
          issued the Notice on Adjustments and Perfection of the Policy on
          Consumer Taxes on 20 March 2006, which imposes consumer tax on
          naphtha, solvent oil and other products, and the costs of raw
          materials for chemical products have increased as a result.

          -    Transaction amount

               As a result of business development, there is an increase of the
          amount of transactions between the Group and the CNPC Group as
          compared with the amount of 8 November 2005 when Independent
          Shareholders' approval for the Existing Caps was sought.

                              LETTER FROM THE BOARD

               The table below sets out the monthly average prices of natural
          gas, refined oil, crude oil, naphtha and solvent oil of PetroChina for

               Due to the above reasons, the Board has considered and proposed
          the following increases to the Existing Caps in respect of this
          category of transaction.

Products and services to be provided by the
   Group to the CNPC Group                    17,536   21,498   23,219


               The above proposed increases to the Existing Caps have been
          determined with reference to the following: historical transaction
          records for products and services provided by the Group to the CNPC
          Group; the actual and estimated increases to the price of relevant
          products; and the actual and estimated business growth of the Group
          and the CNPC Group.

          (ii) Products and services to be provided by the CNPC Group to the
               Group

               (a)  Production services

                    The proposed increases to the Existing Caps of this category
               of transaction are mainly attributable to the fact that due to
               the PRC's increasing demand on crude oil, the Group intends to
               purchase crude oil from CNPC E&D and its subsidiaries in addition
               to the crude oil from the PetroKazakhstan Group as set out in
               section 5 (a) (i) of this circular.

                    Other production services consist of water supply,
               electricity generation and supply, gas supply, transportation,
               etc. by the CNPC Group to the Group. Such increases are
               attributable to the formal commencement of operation of the
               Kazakhstan-China Pipeline and the Western Pipeline in the near
               future and the internal integration of the CNPC Group, which will
               increase its delivery capacity in the refined oil retail market
               in the PRC, thus creating more opportunities of refined oil
               delivery business for the Group.

                    The Board has considered and proposed the following
               increases to the Existing Caps in respect of this category of
               transaction.

To the Independent Board Committee and the Shareholders

Dear Sirs,

                            REVISION OF EXISTING CAPS

     We refer to our engagement as the Independent Financial Adviser to advise
the Independent Board Committee and the Independent Shareholders (or the
Shareholders for CRMSC Transactions) on the fair and reasonableness of the
Proposed Caps for each of the three years ending 31 December 2006, 2007 and
2008. Pursuant to the Listing Rules, the Proposed Caps are subject to, among
other things, the approval of the Independent Shareholders (or the approval of
the Shareholders for the CRMSC Transactions) at a general meeting of PetroChina
Company Limited ("Petrochina"). Details of the Proposed Caps are summarized in
PetroChina's circular to its Shareholders dated 14 September 2006 (the
"Circular"). This letter has been prepared for inclusion in the Circular and
capitalized terms used in this letter shall have the same meaning as defined in
the Circular unless the context otherwise requires.

     On 23 August 2006, PetroChina announced that CNPC E&D, a subsidiary of
PetroChina and a 50 : 50 joint venture between PetroChina and CNODC, entered
into the Acquisition Agreement through the Acquirer (a wholly owned subsidiary
of CNPC E&D) with the Vendor (a wholly owned subsidiary of CNODC), for the
acquisition by the Acquirer of CNODC's entire interest in PetroKazakhstan,
representing 67% of the issued share capital of PetroKazakhstan. Please refer to
the announcement of PetroChina dated 23 August 2006 and "Letter from the Board"
in this Circular for details of the Acquisition.

     As a result of (i) the completion of the Acquisition, certain continuing
connected transactions which will fall within the scope of the Amended
Comprehensive Agreement will arise; and (ii) changes to PetroChina's production
and operational environment that are expected to have an impact on the Existing
Caps, PetroChina proposes to revise the Existing Caps under the Amended
Comprehensive Agreement and the CRMSC Products and Services Agreement as
previously approved by the Independent Shareholders (or by the Shareholders for
the CRMSC Transactions) on 8 November 2005. The Proposed Caps for the three
years ending 31 December 2008 are subject to reporting, announcement and
independent shareholders' approval requirements under the Listing Rules.

     Our opinion only applies to the Proposed Caps subject to Independent
Shareholders' approval (or the Shareholders' approval for the CRMSC
Transactions). All other connected transactions, continuing connected
transactions and their respective caps that are not subject to independent
shareholders' approval under the Listing Rules are not within the scope of our
work.

                  LETTER FROM THE INDEPENDENT FINANCIAL ADVISER

     We, ICEA Capital Limited, have been retained as the Independent Financial
Adviser to advise the Independent Board Committee and the Independent
Shareholders (or Shareholders for the CRMSC Transactions) as to whether the
Proposed Caps are fair and reasonable so far as the Independent Shareholders (or
Shareholders for the CRMSC Transactions) are concerned.

     In formulating our recommendation, we have relied, without assuming any
responsibility for independent verification, on the information, opinions and
facts supplied and representations made to us by the Directors, who have assumed
full responsibility for the accuracy of the information contained in the
Circular, and that any information and representations made to us are true,
accurate and complete in all material respects as at the date hereof and that
they may be relied upon. We have no reason to doubt the truth, accuracy and
completeness of the information and representation provided to us by PetroChina.
We have discussed with the management of PetroChina regarding their plans and
prospects of PetroChina. We have also relied on certain information available to
the public and have assumed such information to be accurate and reliable, and we
have not independently verified the accuracy of such information. We have
studied the relevant market and other conditions and trends relevant to the
Proposed Caps. We have also assumed that statements and representations made or
referred to in the Circular were accurate at the time they were made and
continue to be accurate at the date of the Circular.

     We consider that we have reviewed sufficient information to reach an
informed view in order to provide a reasonable basis for our advice. We have
not, however, carried out any independent verification of the information
provided to us nor have we conducted any form of in-depth investigation into the
business affairs or assets and liabilities of PetroChina, the CNPC Group,
PetroKazakhstan or any of their respective subsidiaries or associated companies.
Additionally, we did not conduct any physical inspection of the properties or
facilities of PetroChina, the CNPC Group, PetroKazakhstan or any of their
respective subsidiaries or associated companies. It is not within our terms of
engagement to comment on the commercial feasibility of the continuing connected
transactions, which remains the responsibility of the Directors. As the
Independent Financial Adviser to the Independent Board Committee and the
Independent Shareholders (or to the Shareholders for CRMSC Transactions), we
have not been involved in the negotiations in respect of the terms of the
continuing connected transactions and the determination of the Proposed Caps.
Our opinion has been made on the assumption that all obligations to be performed
by each of the parties to the continuing connected transactions will be fully
performed in accordance with the terms thereof.

     Our opinion is necessarily based upon the financial, economic, market,
regulatory, and other conditions as they exist on, and the facts, information,
and opinions made available to us as of the date of this letter. We have no
obligation to update this opinion to take into account events occurring after
the date that this opinion is delivered to the Independent Board Committee and
the Independent Shareholders (or to the Shareholders for CRMSC Transactions).
This letter is for the information of the Independent Board Committee and the
Shareholders solely in connection with their consideration of the Proposed Caps
and, except for its inclusion in the Circular, is not to be quoted or referred
to, in whole or in part, nor shall this letter be used for any other purpose,
without our prior written consent.

PRINCIPAL FACTORS CONSIDERED

     In arriving at our opinion, we have taken into consideration the principal
factors and reasons set out below. In reaching our conclusion, we have
considered the results of the analyses in light of each other and ultimately
reached our opinion based on the results of all analyses taken as a whole.


                                      -18-



                  LETTER FROM THE INDEPENDENT FINANCIAL ADVISER

     1.   Background of the continuing connected transactions under the Amended
          Comprehensive Agreement and the CRMSC Products and Services Agreement

          The Amended Comprehensive Agreement was initially entered into between
     PetroChina and CNPC on 10 March 2001, which was amended on 9 June 2005 and
     1 September 2005 respectively. On 1 September 2005, PetroChina and CRMSC
     entered into the CRMSC Products and Services Agreement.

          Detailed information about the terms and conditions of the continuing
     connected transactions under the Amended Comprehensive Agreement and the
     CRMSC Products and Services Agreement were disclosed in the circular of
     PetroChina to the Shareholders dated 22 September 2005.

     2.   Reasons for revision of the Existing Caps

          As stated in the Letter from the Board in the Circular, PetroChina
     proposes to revise the Existing Caps under the Amended Comprehensive
     Agreement and the CRMSC Products and Services Agreement as previously
     approved by the then Independent Shareholders (or by the then Shareholders
     for the CRMSC Transactions) on 8 November 2005. The revision of the
     Existing Caps to the Proposed Caps for the three years ending 31 December
     2006, 2007 and 2008 are the result of:

          (i)  continuing connected transactions arising as a result of the
               completion of the Acquisition, which will fall within the scope
               of the Amended Comprehensive Agreement; and

          (ii) changes to PetroChina's production and operational environment
               that are expected to have an impact on the Existing Caps under
               the Amended Comprehensive Agreement and the CRMSC Products and
               Services Agreement.

     3.   Revision of the Existing Caps

          3.1  Revision due to the continuing connected transactions arising as
               a result of the Acquisition

               Given the business size of the PetroKazakhstan Group and the fact
          that the transactions between the PetroKazakhstan Group and the CNPC
          Group will fall within the scope of the Amended Comprehensive
          Agreement upon completion of the Acquisition, we considered that
          revision of the Existing Caps to the Proposed Caps is fair and
          reasonable and in the interest of PetroChina and the Shareholders.

               The proposed increases to the Existing Caps as a result of the
          Acquisition are summarized as follows:



                                                 Proposed increases to
                                                   the Existing Caps

                  LETTER FROM THE INDEPENDENT FINANCIAL ADVISER

          3.1.1 Production services to be provided by the CNPC Group to the
               Group

               The proposed increases to the Existing Caps for the products and
          services to be provided by the CNPC Group to the Group have been
          determined with reference to:

               (i)  the estimated growth in crude oil production and business of
                    the PetroKazakhstan Group;

               (ii) current market prices of crude oil;

               (iii) potential fluctuations and increases in the prices of crude
                    oil both in the international market and in the domestic
                    market;

               (iv) the estimated annual crude oil volume to be purchased by the
                    Group from the PetroKazakhstan Group;

               (v)  the transportation capacities of the Kazakhstan-China
                    Pipeline and the Western Pipeline; and

               (vi) charges of the Kazakhstan-China Pipeline and the Western
                    Pipeline for oil transportation and the potential
                    fluctuations and increases in such charges.

               The proposed increases to the Existing Caps for the production
          services to be provided by the CNPC Group to the Group for the three
          years ending 31 December 2006, 2007 and 2008 are mainly due to the
          proposed purchase of the crude oil from the PetroKazakhstan Group and
          transportation of such crude oil through the Kazakhstan-China Pipeline
          and the Western Pipeline in accordance with the Amended Comprehensive
          Agreement as a result of the Acquisition.

               Part of the Kazakhstan-China Pipeline and the Western Pipeline
          has been put into service in 2006. Based on the information provided
          by PetroChina, the Group plans to purchase 3.5 million tons, 10
          million tons and 10 million tons of crude oil from the PetroKazakhstan
          Group for 2006, 2007 and 2008 respectively. The proposed increases in
          transaction amounts are estimated based on the transportation capacity
          of the two pipelines, the business development of the Group, the
          current crude oil market and the estimated commodity price of crude
          oil price with reference to the average Brent crude oil future price
          of approximately US$64.7 per barrel in early 2006 as quoted in
          Bloomberg.

               In light of the above and taken into consideration of (i) the
          discussion with the management of PetroChina on the business plan of
          the PetroKazakhstan Group, including its estimated growth in crude oil
          production and the expected time frame for the full-scale operation of
          the Kazakhstan-China Pipeline and the Western Pipeline; and (ii) the
          continuing business growth of the Group as well as the anticipated
          increase in future crude oil price (both internationally and
          domestically), we are of the view that the proposed purchase price
          used in estimating the proposed caps is reasonable and the proposed
          increases to the Existing Caps for this type of transactions are
          fairly and reasonably determined.


                                      -20-



                  LETTER FROM THE INDEPENDENT FINANCIAL ADVISER

          3.1.2 Construction and technical services to be provided by the CNPC
               Group to the Group

               The proposed increases to the Existing Caps for construction and
          technical services to be provided by the CNPC Group to the Group have
          been determined with reference to:

               (i)  the historical transactions and transaction amounts for the
                    construction and technical services of the PetroKazakhstan
                    Group; and

               (ii) the estimated business growth of the PetroKazakhstan Group.

               After the Acquisition, the PetroKazakhstan Group will expedite
          its development and increase capital expenditure in the next three
          years. As stated in the Letter from the Board of this Circular, given
          that the construction and technical services provided to the Group by
          the CNPC Group are of a high quality and on favourable in pricing
          term, the Group (including the PetroKazakhstan Group) will continue to
          obtain construction and technical services from the CNPC Group after
          the Acquisition. We have discussed with the management of PetroChina
          on the future capital expenditure plan of PetroKazakhstan and have
          reviewed the relevant documents and information (in particular, the
          historical transactions and transaction amounts), and considered the
          plan was prepared after due and careful enquiry. As such, we are of
          the view that the proposed increases to the Existing Caps for this
          type of services are determined on a fair and reasonable basis and are
          sufficient for the Group to capture the future anticipated expansion
          plan of the PetroKazakhstan Group.

          3.1.3 Material supply services to be provided by the CNPC Group to the
               Group

               The proposed increases to the Existing Caps for material supply
          services to be provided by the CNPC Group to the Group have been
          determined with reference to:

               (i)  historical prices and transaction amounts in respect of
                    material supply transactions of the PetroKazakhstan Group;

               (ii) estimated business growth of the PetroKazakhstan Group; and

               (iii) estimated changes in the volume of purchases by the
                    PetroKazakhstan Group.

               The proposed increases are mainly attributable to the provision
          of casing pipes, drill heads, drilling liquid and lubricating oil and
          other raw materials or equipment by the CNPC Group to the
          PetroKazakhstan Group for its ordinary daily operation.

               We understand from the management of PetroChina that the CNPC
          Group and other independent international suppliers will be invited to
          tender for the provision of material supply services to the
          PetroKazakhstan Group. However, based on their past experience, the
          CNPC Group has competitive advantage over other suppliers on the
          quality and the price of the services.

               The proposed increases to the Existing Caps for this type of
          transactions are based on the potential demand for the materials and
          equipment of the PetroKazakhstan Group in accordance with its business
          development plan as well as the estimated cost incurred with the
          related materials and equipment. Based on (i) the discussion with the
          management of PetroChina on the future plan of the PetroKazakhstan
          Group and the possibility for the CNPC Group to obtain contracts for
          provision of material supply services to the PetroKazakhstan Group;
          and (ii) the

                  LETTER FROM THE INDEPENDENT FINANCIAL ADVISER

          review on the relevant documents and information (in particular, the
          historical transactions and transaction amounts), we are of the view
          that the proposed increases to the Existing Caps are determined on a
          fair and reasonable basis.

          3.2  Revision due to changes to PetroChina's production and
               operational environment

                    The proposed increases to the Existing Caps for the
               production services to be provided by the CNPC Group to the Group
               have been determined with reference to:

                    (i)  historical transaction records for the production
                         services provided by the CNPC Group to the Group;

                    (ii) the medium and long term development plan of the Group;

                    (iii) the actual and estimated business growth of the Group;
                         and

                    (iv) the potential increase in the international and
                         domestic market prices of crude oil, petroleum and
                         other petrochemical products.

                    Being a major producer and supplier of crude oil in the PRC,
               PetroChina has the responsibilities on satisfying the national
               energy demands. In this connection, part of the crude oil from
               CNPC E&D will be send back to the Group in the PRC for refining
               and processing, and sold in the domestic market. Approximately 5%
               of the crude oil production of CNPC E&D in 2005 was sent back to
               the domestic market through PetroChina following the completion
               of PetroChina's acquisition of interest in CNPC E&D in November
               2005.

                  LETTER FROM THE INDEPENDENT FINANCIAL ADVISER

               Since CNPC E&D is expected to speed up its business expansion in
               the international market in the near future, PetroChina believed
               that more crude oil will be sold from CNPC E&D to the Group in
               order to meet the strong domestic demand in the next years.

                    In addition, we understand from the management of PetroChina
               that (i) the full-scale operation of Kazakhstan-China Pipeline
               and Western Pipeline is expected to be commenced in 2007, which
               is earlier than previously expected in September 2005; and (ii)
               following the internal integration beginning from June 2005, the
               CNPC Group has established an advanced transportation company
               which is equipped with modern machines for petroleum and other
               petrochemical products and able to provide transportation
               services with higher efficiency and quality and competitive
               advantage on the quality and price of such services. In view of
               the above, the management of PetroChina considered that there
               will be increased opportunities of refined oil delivery business
               for the Group than that as anticipated in September 2005, and
               hence, increasing the other production services to be provided by
               the CNPC Group to the Group such as water supply, electricity
               generation and supply, gas supply and transportation.

                    We also noted that the actual transaction amount for the
               production services provided by the CNPC Group to the Group for
               the first six months ended 30 June 2005 was approximately
               RMB8,945 million, representing approximately 38.3% of the total
               transaction amount of the whole year of 2005. Based on the
               information of PetroChina, the actual transaction amount for the
               same type of services for the first six months ended 30 June 2006
               was approximately RMB17,058 million, representing approximately
               62.0% of the Existing Cap for 2006 and approximately 33.5% of the
               Proposed Cap for 2006.

                    result of the Acquisition as refer in paragraph 3.1.1 above.

               Given the increasing demand of crude oil from CNPC E&D, the
          increased opportunities of refined oil delivery business for the Group
          and that the proposed caps are in line with the historical data, we
          consider the revision of the Existing Caps is fair and reasonable so
          far as the Group and Shareholders concerned and the Proposed Caps have
          been determined on a fair and reasonable basis.

                  LETTER FROM THE INDEPENDENT FINANCIAL ADVISER

               (b)  Construction and technical services to be provided by the
                    CNPC Group to the Group

                    The proposed increases to the Existing Caps for the
               construction and technical services to be provided by the CNPC
               Group to the Group have been determined with reference to:

                    (i)  historical transaction records for the construction and
                         technical services provided by the CNPC Group to the
                         Group;

                    (ii) the medium and long term development plan of the Group;

                    (iii) the actual and the estimated business growth of the
                         Group;

                    (iv) the increases of prices of relevant oil products; and

                    (v)  the estimated relevant service price.

                    The construction and technical services to be provided by
               the CNPC Group to the Group are mainly related to development of
               oilfields, including but not limited to exploration technology
               service, down hole operation service, oilfield construction
               service, oil refinery construction service and project
               supervision and design service.

                    We understand from the management of PetroChina that after
               Existing Caps were determined in 2005, there has been important
               oil exploration discovery on three major oilfields of PetroChina
               (including Ji Dong oilfields). Accordingly, PetroChina plans to
               substantially increase its capital and expenditure budget in the
               three years ending 31 December 2006, 2007 and 2008 to cater for
               the development of such oilfields.

                    Even assuming that there was no breakthrough in oil
               exploration discovery on such oilfields and they were developed
               as originally planned, the overall transaction amount of the
               construction and technical services of the Group for the three
               years ending 31 December 2008 is expected to rise because of the
               increase of the crude oil price since last September. According
               to Platts, the world's leading provider of energy information,
               the Minas Crude Oil price as quoted in Singapore Market was
               around US$60.5 per barrel in September 2005 when the Existing
               Caps were estimated and reached as high as US$74.1 per barrel in
               July 2006. Since certain amount of oil products (such as gasoline
               and diesel oil) will be consumed to generate power during the
               course of providing the construction and technical services (such
               as well drilling) to the Group, the increase in the crude oil
               price is expected to substantially increase the operational cost
               for construction and technical service providers. Based on the
               information provided by PetroChina, we noted that approximately
               256,000 tons and 1,379,000 tons of gasoline and diesel oil are
               expected to be consumed respectively in connection with the
               provision of the construction and technical service in 2006.

                    Despite the construction and technical services for
               development of such oilfields will be put out to tender, it is
               likely that the CNPC Group would win the bid and provide such
               services to the Group because of the large production capability
               and competitive strengths of the CNPC Group on the oil
               construction and technical services industry.

                    Given the breakthrough in the oil exploration on some
               oilfield of PetroChina and the substantial increase in
               development costs because of the increase in crude oil price
               since last September, we are of the view that the revision of the
               Existing Caps for this type of


                                      -24-



                  LETTER FROM THE INDEPENDENT FINANCIAL ADVISER

               services is in the interest of PetroChina so to capture the
               future anticipated business expansion and the respective Proposed
               Caps have been determined on a fair and reasonable basis.

               (c)  Material supply services to be provided by the CNPC Group to
                    the Group

                    The proposed increases to the Existing Caps for the material
               supply services to be provided by the CNPC Group to the Group
               have been determined with reference to:

                    (i)  historical transaction records for the supply of
                         materials services provided by the CNPC Group to the
                         Group;

                    (ii) the medium and long term development plan of the Group;

                    (iii) the actual and the estimated business growth of the
                         Group; and

                    (iv) the actual and estimated prices of relevant materials.

                    Pursuant to the Amended Comprehensive Agreement, the Group
               obtains material supply services from the CNPC Group. Such
               material supply services are mainly for facilitating the daily
               operation of the Group, including but not limited to purchase of
               materials, quality control, storage of materials and delivery of
               materials. As such, the transaction amounts of this type of
               services proportionate to the scale of PetroChina's production
               and operation.

                    Given the unexpected expansion of the business of PetroChina
               in the near future as analyzed in above paragraphs (a) and (b),
               we are of the view that revision of the Existing Caps is
               necessary and the proposed increases to the Existing Caps for
               this type of services are determined on a fair and reasonable
               basis.

          3.2.2 Products and services to be provided by the Group to the CNPC
               Group

               The proposed increases to the Existing Caps for the products and
          services to be provided by the Group to the CNPC Group have been
          determined with reference to:

               (i)  historical transaction records for products and services
                    provided by the Group to the CNPC Group;

               (ii) the actual and estimated increases to the price of relevant
                    products; and

               (iii) the actual and estimated business growth of the Group and
                    the CNPC Group.

               The Amended Comprehensive Agreement provides that the Group
          should supply products such as natural gas, crude oil and refined oil
          and other products to the CNPC Group at the government-prescribed
          price, or where there is no government-prescribed price, the price
          shall be determined with reference to the market price. However, as
          explained in the Letter from the Board in this Circular, since the
          approval of the Existing Caps in 2005, the prices of certain major oil
          products to be supplied by the Group to the CNPC Group has
          substantially increased.

               -    Natural Gas

                    Pursuant to the Notice on the Reform of the Mechanism for
               Determining the Ex- Factory Prices of Natural Gas and Recent
               Appropriate Increase of the Ex-Factory Prices of Natural Gas
               issued by the National Development and Reform Commission on 23
               December 2005, the government-prescribed ex-factory price of
               natural gas increased by approximately 17.95% since 26 December
               2005 and the PRC government plans to increase the price of
               natural gas in the next five years.

               -    Refined oil

                    The National Development and Reform Commission has issued
               two notices on the adjustment to the prices of refined oil on 26
               March 2006 and 24 May 2006. Pursuant to the two notices, the
               government-prescribed ex-factory prices of refined oil have
               increased by approximately 52%.

               -    Crude oil

                    Currently, the crude oil prices in the domestic market of
               the PRC are in line with the crude oil prices in the
               international market. As stated above, the Minas Crude Oil price
               as quoted in Singapore Market was US$60.5 per barrel in September
               2005 when the Existing Caps were estimated and reached as high as
               US$74.1 per barrel in July 2006.

               -    Naphtha, solvent oil

                    Pursuant to the Notice on Adjustments and Perfection of the
               Policy on Consumer Taxes issued by the Ministry of Finance and
               the State Administration of Taxation on 20 March 2006, consumer
               tax is imposed on naphtha, solvent oil, and other products since
               1 April 2006, increasing the costs of raw materials for chemical
               products.

               In addition, PetroChina's middle and long term development goal
          has been adjusted with respect to the chemicals and marketing segment
          and refining and marketing segment to further increase its production
          capacity of these segments. With the anticipated increase in its
          production capacity, increasing demands for products and services as
          well as the enlarged business scale and new business development of
          the CNPC Group, PetroChina is able to supply more products and
          services to the CNPC Group.

               We noted that based on the information provided by PetroChina,
          the actual transaction amount for the products and services provided
          by the Group to the CNPC Group for the first half of 2005 was
          approximately RMB6,932 million, representing approximately 35.0% of
          the total transaction amount for the whole year 2005. However, the
          actual transaction amount of the first half of 2006 was approximately
          RMB13,447 million, representing approximately 70.3% of the Existing
          Cap for 2006 and approximately 36.7% of the Proposed Cap for 2006.

                    increase due to the effect of the changes to the operational
                    environment of the Group.

               In light of the above and given that the unexpected business
          expansion of the Group as well as the anticipated increase in the
          prices for oil products, we are of the view that the revision of the
          Existing Cap for this type of services is fair and reasonable and the
          proposed increases to the Existing Caps are determined on a fair and
          reasonable basis.

          3.2.3 Products and services to be provided by the Group to CRMSC

               The proposed increases to the Exiting Caps for products and
          services to be provided by the Group to CRMSC have been determined
          with reference to:

               (i)  the Group's historical transaction records with CRMSC;

               (ii) the estimated business growth of the Group and CRMSC; and

               (iii) the actual and estimated price of refined oil.

               PetroChina entered into the CRMSC Products and Services Agreement
          with CRMSC on 1 September 2005, pursuant to which PetroChina should
          provide CRMSC with products and services including, among other
          things, refined products (such as gasoline, diesel and other petroleum
          products) on a continuing basis. Detailed information about the terms
          and conditions of the CRMSC Products and Services Agreement was
          disclosed in the circular of PetroChina to the Shareholders dated 22
          September 2005.

               We understand from the management of PetroChina that the supply
          of refined products to CRMSC constituted a substantial proportion of
          the CRMSC Transactions. In view that the government-prescribed price
          of refined oil in the PRC has increased, we consider that the revision
          of the Existing Cap for this type of services is in the interest of
          PetroChina and the Shareholders as a whole and the proposed increases
          to the Existing Caps are fairly and reasonably determined.

                  LETTER FROM THE INDEPENDENT FINANCIAL ADVISER

     4.   Annual review of non-exempted continuing connected transactions

          As discussed with PetroChina, it will comply with the annual review
     requirements of the Stock Exchange, in particular:

               (i)  Each year the independent non-executive Directors must
                    review the continuing connected transactions and confirm in
                    the annual report that the transactions have been entered
                    into:

                    -    in the ordinary and usual course of business of
                         PetroChina;

                    -    either on normal commercial terms or, if there are not
                         sufficient comparable transactions to judge whether
                         they are on normal commercial terms, on terms no less
                         favourable to PetroChina than terms available to or
                         from (as appropriate) independent third parties; and

                    -    in accordance with the relevant agreement governing
                         them on terms that are fair and reasonable and in the
                         interests of the Shareholders as a whole; and

               (ii) Each year the auditors must provide a letter to the
                    Directors (with a copy provided to the Stock Exchange at
                    least 10 business days prior to the bulk printing of
                    PetroChina's annual report), confirming that the continuing
                    connected transactions:

                    -    have received the approval of the Directors;

                    -    are in accordance with the pricing policies of
                         PetroChina if the transactions involve provision of
                         goods or services by PetroChina;

                    -    have been entered into in accordance with the relevant
                         agreement governing the transactions; and

                    -    have not exceeded the caps approved by the Independent
                         Shareholders (or by the Shareholders for CRMSC
                         Transactions) and disclosed in previous
                         announcement(s).

          Based on the above, we are of the view that there are appropriate
     measures in place to monitor the non-exempted continuing connected
     transactions and protect the interest of PetroChina and the Shareholders as
     a whole.

RECOMMENDATION

     Having considered the above principal factors and reasons, we consider that
the revision of the Existing Caps is in the interest of PetroChina and the
Shareholders as a whole, and the Proposed Caps are determined on a fair and
reasonable basis and are in the interest of PetroChina and the Independent
Shareholders (or the Shareholders for CRMSC Transactions) as a whole.
Accordingly, we advise the Independent Board Committee to recommend the
Independent Shareholders (or the Shareholders for CRMSC Transactions) to vote in
favor of the relevant ordinary resolutions in the EGM.
