SUMMARY

(A)  THE ACQUISITION

PetroChina announces 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) on 23 August 2006, for the acquisition by the
Acquirer of CNODC's entire interest in PetroKazakhstan, representing 67% of the
issued share capital of PetroKazakhstan.

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 is exempted from the independent
shareholders' approval requirement under Rule 14A.32 of the Listing Rules.


(B)  CONTINUING CONNECTED TRANSACTIONS

1.   REVISION OF 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 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:

     o    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

     o    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 announcement.

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.


2.   TRANSACTIONS WITH CNPC (HK)

The Group obtained a waiver from the Stock Exchange on 2 January 2004 from
strict compliance with the disclosure requirement of the Listing Rules in
respect of the CNPC (HK) Transactions for a period of three financial years
ending 31 December 2006. The Board approved the CNPC (HK) Caps for the period
from 1 January 2007 to 31 December 2008 at its meeting held on 23 August 2006.

Given that the relevant percentage ratios involved the CNPC (HK) Transactions
are more than 0.1% but less than 2.5% for the Group, they are only subject to
reporting and announcement requirements and exempted from the independent
shareholders' approval requirement under Rule 14A.34 of the Listing Rules.


(C)  AMENDMENTS TO THE ARTICLES

PetroChina proposes to expand its business scope and to amend its Articles
accordingly. The proposed amendments to the Articles will be subject to the
approval of Shareholders.

A circular containing, among other things, details of the Proposed Caps, the
proposed amendments to the Articles, a letter from the Independent Financial
Adviser, a recommendation by the Independent Board Committee and a notice
convening an extraordinary general meeting of PetroChina to approve the Proposed
Caps and proposed amendments to the Articles will be sent to the Shareholders as
soon as possible.


FINANCIAL ADVISER

Deutsche Bank AG, Hong Kong Branch is the financial adviser to PetroChina in
respect of the Acquisition.


(A)  THE ACQUISITION

1.   BACKGROUND TO THE ACQUISITION

(a)  ACQUISITION OF CNPC E&D

On 9 June 2005, PetroChina entered into an agreement with CNODC, Central Asia
Petroleum Company Limited and CNPC E&D to acquire a 50% interest in CNPC E&D.
Pursuant to this agreement, CNPC E&D obtained a contractual priority right to
(a) require CNODC or its subsidiaries to sell to CNPC E&D; or (b) purchase from
CNODC or its subsidiaries, certain assets owned by CNODC or its subsidiaries
relating to the exploration, development, production, pipeline and refining
businesses of crude oil and natural gas in areas outside the PRC. Detailed
information about this acquisition and the priority right was set out in the
circular to the Shareholders dated 30 June 2005. This acquisition was approved
by the extraordinary general meeting of PetroChina held on 16 August 2005 and
was completed on 29 November 2005.


(b)  THE CNPCI ACQUISITION

On 21 August 2005, CNODC, through its wholly-owned subsidiary CNPCI, entered
into an arrangement agreement with PKZ, pursuant to which CNPCI acquired the
entire issued share capital of PKZ at US$55 per share (with a total
consideration of approximately US$4.08 billion) through 818 Inc., a wholly-owned
subsidiary of CNPCI incorporated in Canada ("CNPCI ACQUISITION"). The CNPCI
Acquisition was completed on 26 October 2005. Following completion of the CNPCI
Acquisition, PKZ became an indirect wholly-owned subsidiary of CNODC.

After the completion of the CNPCI Acquisition, PetroChina promptly procured CNPC
E&D to negotiate with CNODC for the exercise of its contractual priority right
to purchase its interest in PKZ to the extent permitted by applicable laws. A
clarification announcement was published by PetroChina on 15 December 2005 in
this regard.


(c)  KAZAKH GOVERNMENT'S STATUTORY PRE-EMPTIVE RIGHT

According to the Kazakhstan Subsoil Use Law, the government of the Republic of
Kazakhstan holds a statutory right of pre-emption over any transfers of any
subsoil use interest. This statutory pre-emptive right applies to the CNPCI
Acquisition and the proposed transfer by CNPCI of its interests in PKZ to CNPC
E&D.

In connection with the process of obtaining a wavier of the statutory
pre-emptive right from the government of the Republic of Kazakhstan, CNODC,
through its wholly-owned subsidiary CNPCI, entered into a memorandum of
understanding with KMG on 15 October 2005, pursuant to which CNPCI agreed to
sell 33% (on a fully diluted basis) of the total issued share capital of PKZ to
KMG at a purchase price of US$55 per share ("KMG ACQUISITION") and KMG agreed to
assist PKZ in applying for a waiver from the government of the Republic of
Kazakhstan for its statutory pre-emptive right.

On 12 May 2006, CNPCI and KMG agreed that 818 Inc. and PKZ would amalgamate
under the laws of the Province of Alberta, Canada and that the new company
resulting from the Amalgamation would become the owner of all of the assets and
liabilities of PKZ and 818 Inc. (except the shares of PKZ). The Amalgamation was
completed on 29 June 2006 and the new company's name remains the same as
PetroKazakhstan Inc. ("PETROKAZAKHSTAN").


On 4 July 2006, the Ministry of Energy and Mineral Resources of the Republic of
Kazakhstan approved the CNPCI Acquisition, the Amalgamation, the KMG Acquisition
and the proposed transfer by CNPCI of its interests in PetroKazakhstan to CNPC
E&D.

On 5 July 2006, CNPCI, the Vendor (a wholly owned subsidiary of CNODC), KMG and
KMGS further entered into the Interest Purchase Agreement, pursuant to which the
Vendor agreed to sell and KMGS agree to purchase 33% of the total issued share
capital of PetroKazakhstan at a purchase price of US$55 per share. The KMG
Acquisition was completed on 5 July 2006.


2.   THE ACQUISITION AGREEMENT

(a)  PRINCIPAL TERMS

The Vendor and the Acquirer entered into the Acquisition Agreement on 23 August
2006, for the sale by the Vendor, and the acquisition by the Acquirer, of
49,732,760 common shares in PetroKazakhstan, representing 67% of the total
issued and outstanding common shares of PetroKazakhstan and CNODC's entire
interest in PetroKazakhstan.

The Acquirer is a wholly owned subsidiary of Pervinage, which is in turn an
indirect wholly owned subsidiary of CNPC E&D. CNPC E&D is a subsidiary of
PetroChina and a 50:50 joint venture between PetroChina and CNODC.


(b)  CONSIDERATION

The aggregate consideration for the Acquisition is US$2,735,301,800, equivalent
to US$55 per share and the per share consideration paid by KMG and KMGS to the
Vendor pursuant to the KMG Acquisition described above.

The Acquisition was negotiated and entered into on an arm's length basis and on
normal commercial terms. The total consideration was determined following
negotiation with the Vendor and is based on, amongst other things, the results
of due diligence, as well as PetroChina's valuation analysis by reference to
PetroKazakhstan's production, operating costs and capital expenditures analysis
conducted by McDaniel & Associates Consultants Ltd., an independent reserves
valuer.

The consideration will be paid on the closing date of the Acquisition by the
payment of cash in RMB or U.S. dollars. The consideration will be funded by a
combination of CNPC E&D's internal resources and debt financing.

The Board (including independent non-executive directors) is of the view that
the total consideration payable by the Acquirer for the Acquisition and the
other terms of the Acquisition Agreement are fair and reasonable and the
Acquisition is in the best interests of PetroChina and its Shareholders as a
whole.

4.   OTHER TERMS OF THE ACQUISITION

(a)  CONDITIONS PRECEDENT

The closing of the Acquisition is conditional on the fulfillment of certain
conditions, including:

(i)   the obtaining of all necessary approvals from the relevant government
      authorities in Canada, Kazakhstan and the PRC with respect to the
      Acquisition;

(ii)  the accuracy of representations and warranties provided by the Vendor and
      the Acquirer respectively under the Acquisition Agreement; and

(iii) the execution of an assignment and assumption agreement with respect to
      the Shareholders Agreement as further explained in paragraph (c) below;


(b)  CLOSING

The closing of the Acquisition will occur within 14 business days from the date
on which the last of the conditions set out in the Acquisition Agreement is
satisfied or waived, and is expected to take place as soon as practicable and in
any event by no later than 31 December 2006 (unless otherwise agreed by the
Vendor and the Acquirer).


(c)  ARRANGEMENTS WITH KMG

(i)  Shareholders Agreement

As a condition of the transfer of the 67% interest in PetroKazakhstan by the
Vendor to the Acquirer, the Acquirer will enter into an assignment and
assumption agreement on or before the closing of the Acquisition, pursuant to
which the Pervinage and the Acquirer will assume all of the respective rights,
interests, liabilities and obligations of CNPCI and the Vendor under the
Shareholders Agreement entered into between CNPCI, the Vendor, KMG, KMGS and
PetroKazakhstan dated 5 July 2006. The Shareholders Agreement provides that so
long as KMG and/or any affiliate of KMG collectively hold not less than 16% of
the issued share capital of PetroKazakhstan, each shareholder shall have a veto
right relating to, amongst other things, liquidation of or mergers involving, or
changes to the capital structure of the PetroKazakhstan Group, annual work
programs or annual budgets of PetroKazakhstan and certain related-party
transactions. As a result of these veto rights, KMG is regarded as having
substantive minority participative rights, through such veto rights, which would
enable KMG or KMGS to participate in the operations of PetroKazakhstan and
prevent PetroChina from unilaterally passing key resolutions on a number of key
financial and operating matters of PetroKazakhstan. PetroChina and KMG are
therefore considered as having joint control over PetroKazakhstan and PetroChina
is not in a position to consolidate PetroKazakhstan's accounts in its
consolidated financial statements. PetroKazakhstan will be equity-accounted


for in PetroChina's consolidated financial statements in accordance with
International Accounting Standards. In addition, pursuant to the Shareholders
Agreement, CNPCI has committed to procure PetroKazakhstan to supply certain
crude oil to PKOP's refinery at Shymkent.


(ii) Reorganization of PKOP's interests

PKOP is currently a subsidiary of PetroKazakhstan. The main business of PKOP
includes the operation of a refinery located in Shymkent, the Republic of
Kazakhstan, which does not constitute the core business of the PetroKazakstan
Group. PetroKazakhstan owns approximately 99.7% of PKKR, which owns 100% of
Valsera. Valsera is a holding company of an approximately 96.7% interest in
PKOP. Upon the closing of KMG Acquisition, KMG indirectly holds approximately
33% of Valsera through its interest in PetroKazakhstan.

As part of the arrangements between CNPCI and KMG, CNPCI and KMG entered into
the PKOP MOA on 5 July 2006 with respect to a proposed reorganization of PKOP,
pursuant to which PKKR will transfer a 50% equity interest in Valsera to KMG and
the balance of 50% will be transferred to the Vendor on the terms and conditions
stated in the PKOP MOA. Pursuant to the Acquisition Agreement, the Vendor agreed
to transfer all of its rights and obligations under the PKOP MOA to the
Acquirer. The reorganization is expected to take place as soon as practicable.
If the proposed reorganization of PKOP occurs prior to the completion of the
Acquisition, the Vendor has agreed to transfer all its rights, benefits and
interests derived from the PKOP MOA (including any consideration or payment
received directly or indirectly from KMG or its affiliates for the transfer of
the 50% equity interests in Valsera and the Vendor's remaining 50% equity
interests in Valsera) to the Acquirer for nil consideration. If the proposed
reorganization of PKOP occurs after the completion of the Acquisition, the
Vendor has agreed that the Acquirer shall carry out the reorganization of PKOP
in accordance with the PKOP MOA in place of the Vendor. Accordingly, upon
completion of the PKOP reorganization, the Acquirer will own a 50% direct
interest in Valsera. PetroChina has taken into account of the reorganization of
PKOP's interests in determining the consideration of the Acquisition.


5.   INFORMATION ON PETROKAZAKHSTAN

The business of the PetroKazakhstan Group involves the acquisition, exploration,

6.   REASONS FOR THE ACQUISITION

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.


(a)  FURTHER ENHANCE PETROCHINA'S OVERSEAS WORKING INTERESTS OF OIL AND GAS
     RESERVE

As of 31 December 2005, PetroKazakhstan has gross proven reserves of 340.455
million barrels of oil equivalent with annual production of 42.27 million
barrels of oil equivalent. In addition, PetroKazakhstan has sizeable land
interests, amounting to approximately 4.0 million acres in the South Turgai
basin.


(b)  EXPAND PETROCHINA'S OVERSEAS EXPLORATION AND PRODUCTION ASSETS IN A
     STRATEGICALLY IMPORTANT REGION

PetroKazakhstan's exploration and production assets are strategically located in
a region that enjoys a long history of friendly relations with the PRC and easy
access to the Kazakhstan-China Pipeline.


(c)  DRIVE SYNERGIES FROM THE KAZAKHSTAN-CHINA PIPELINE, THE DUSHANZI REFINERY
     AND CNPC E&D'S EXISTING KAZAKHSTAN EXPLORATION AND PRODUCTION OPERATIONS

PetroKazakhstan is expected to provide synergies with CNPC E&D's existing
operations in Kazakhstan. The Board believes PetroChina would benefit from
improved operating


efficiencies arising from the Acquisition, including by sharing infrastructure,
CNPC E&D's advanced enhanced oil recovery (EOR) technology and management
expertise.

In addition, the Acquisition will further secure the Kazakhstan-China Pipeline
utilization rate, and thus improve its return on investment. The Acquisition
will also secure crude oil supply, in a cost effective manner, to PetroChina's
Dushanzi Refinery which is currently being expanded to double its capacity.


(d)  IMPROVE PETROCHINA'S FINANCIAL PERFORMANCE AND CREATE SHAREHOLDER VALUE IN
     THE LONG TERM

The Acquisition is expected to enhance PetroChina's financial performance and
pave the way for realizing shareholder value in the long term.


7.   INFORMATION REGARDING PETROCHINA, CNODC AND CNPC E&D

(a)  INFORMATION REGARDING PETROCHINA

PetroChina, one of the largest companies in the PRC in terms of sales, is
engaged in a broad range of petroleum and natural gas-related activities,
including:

(i)   the exploration, development, production and sale of crude oil and natural
      gas;

(ii)  the refining, transportation, storage and marketing of crude oil and
      petroleum products;

(iii) the production and sale of basic petrochemical products, derivative
      petrochemical products and other chemical products; and

(iv)  the transmission of natural gas, crude oil and refined products, and the
      sale of natural gas.


(b)  INFORMATION REGARDING CNODC

CNODC is a wholly-owned subsidiary of CNPC. Its primary operations include
international oil and gas production, exploration and development.


(c)  INFORMATION REGARDING CNPC E&D

CNPC E&D is a subsidiary of PetroChina and a joint venture entity held 50:50 by
PetroChina and CNODC.

CNPC E&D's principal activities are international exploration and production of
oil and gas assets. CNPC E&D's operations include oil and gas production assets
in locations including Kazakhstan, Venezuela, Azerbaijan, Peru, Indonesia,
Ecuador, Algeria and the PRC. CNPC E&D also has pipeline assets in locations
including Kazakhstan, refining assets in Algeria and exploration assets in Chad,
Ecuador, Niger, Algeria and Canada.


8.   LISTING RULES IMPLICATIONS

CNODC is wholly owned by CNPC, the controlling shareholder of PetroChina. As at
the date of this announcement, 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.

The Board (including independent non-executive directors) is of the view that
the Acquisition was negotiated and entered into on an arm's length basis and on
normal commercial terms. The terms (including but not limited to the
consideration payable by the Acquirer for the Acquisition) of the Acquisition
Agreement are fair and reasonable and that the Acquisition is in the best
interests of PetroChina and its Shareholders as a whole.


(B)  CONTINUING CONNECTED TRANSACTIONS

1.   REVISION OF 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 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:

     o    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

     o    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 announcement.

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 paragragh headed "(A) The Acquisition - 4. Other Terms of
the Acquisition -- (c) Arrangements with KMG -- (i) Shareholders Agreement"
above, 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.

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.

A circular containing, among other things, details of the Proposed Caps, a
letter from the Independent Financial Adviser, a recommendation by the
Independent Board Committee and a notice convening an extraordinary general
meeting of PetroChina to approve the Proposed Caps will be sent to the
Shareholders as soon as possible.


(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)

CATEGORY OF PRODUCTS AND SERVICES              2006            2007             2008
                                                                    

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


     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)

CATEGORY OF PRODUCTS AND SERVICES               2006            2007             2008
                                                                       

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


      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
                                                           (RMB in millions)

CATEGORY OF PRODUCTS AND SERVICES               2006             2007             2008
                                                                        

 Material supply services to be                  240              480              480
  provided by the CNPC Group to the
  Group


      The above 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.

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

      o     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.

      o     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.

      o     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.

      o     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.

      o     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.

      The table below sets out the monthly average prices of natural gas,
      refined oil, crude oil, naphtha and solvent oil of PetroChina for April
      2005 (when PetroChina performed its estimates for the Existing Caps),
      September 2005 (when PetroChina announced and applied for the
      Shareholders' approval on the Existing Caps) and July 2006:

      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.



                                             PROPOSED INCREASES TO THE EXISTING CAPS

 provided by the Group to the
  CNPC Group


      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 (B)1(a)(i) of this
      announcement.

      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.

2.    TRANSACTIONS WITH CNPC (HK)

As at the date of this announcement, CNPC (HK) is a 51.99% subsidiary owned by
CNPC and therefore a connected person of PetroChina. PetroChina entered into two
production sharing contracts with CNPC (HK), pursuant to which PetroChina agreed
to share in the oil and natural gas produced from Karamay Oilfield, as to 46% by
PetroChina and 54% by the CNPC (HK) Group and from the Leng Jiapu Oilfield, as
to 30% by PetroChina and 70% by the CNPC (HK) Group. Detailed information about
the CNPC (HK) Transactions was disclosed by PetroChina in an announcement on 30
December 2003.

Pursuant to these production sharing contracts, the CNPC (HK) Transactions
include the following:

      The Group has provided and shall continue to provide assistance to the
      CNPC(HK) Group, for among other things, leasing warehouses and terminal
      facilities, and obtaining transportation and communication facilities. For
      such assistance, the CNPC (HK) Group pays an annual assistance fee of US$
      50,000 for each of the Karamay Oilfield and the Leng Jiapu Oilfield.

      The CNPC(HK) Group has paid and shall continue to pay the Group an amount
      of US$50,000 annually for training of personnel for each of the Karamay
      Oilfield and the Leng Jiapu Oilfield.

(ii)  Products provided by the CNPC (HK) Group to the Group


      Although there is no contractual obligation upon the Group to purchase oil
      production of the Karamay Oilfield and the Leng Jiapu Oilfield from the
      CNPC (HK) Group, the Group has and intends to continue to accept part of
      the deliveries in order to save transportation costs. The price of various
      grades of crude oil sold is determined with reference to the prevailing
      price in arm's length transactions of a similar quality crude oil prices
      with reference to the trend of the international oil prices.

The Group obtained a waiver from the Stock Exchange on 2 January 2004 from
strict compliance with the disclosure requirement of the Listing Rules in
respect of the CNPC (HK) Transactions for a period of three financial years
ending 31 December 2006. The table below sets out the cap amounts of the CNPC
(HK) Transactions for the three years ending 31 December 2006:



                                                                CNPC (HK) CAPS

Notes:
(1) The caps are based on 3% of the book value of the Group's net tangible
assets of the relevant years pursuant to the waiver from the Stock Exchange on 2
January 2004.

(2) The cap for 2006 is based 3% of the book value of the Group's net tangible
assets of 2005.

Given that the relevant percentage ratios involved the CNPC (HK) Transactions
are more than 0.1% but less than 2.5% for the Group, they are only subject to
reporting and announcement requirements and exempted from the independent
shareholders' approval requirement under Rule 14A.34 of the Listing Rules. On
its meeting held on 23 August 2006, the Board approved the CNPC (HK) Caps for a
period from 1 January 2007 to 31 December 2008 as follows. The Board (including
independent non-executive directors) is of the view that the CNPC (HK) Caps are
fair and reasonable and in the best interests of PetroChina and its Shareholders
as a whole.
