The Company and all members of its board of directors warrant the authenticity,

The board of directors of the Company is pleased to announce that on 27 December
2007, the Company entered into the "Capital Injection Agreement Concerning CNPC
Exploration and Development Company Limited" with CNODC and CNPC E&D (a
subsidiary of the Company) pursuant to which the Company and CNODC, as
shareholders of CNPC E&D, shall inject capital in the aggregate amount of RMB16
billion (approximately HK$16,944 million) into CNPC E&D. The Company and CNODC
shall each make a capital injection of RMB8 billion (approximately HK$8,472
million) in cash, payable in one lump sum. Upon completion of the Capital
Injection, the Company and CNODC will continue to hold 50% of the shares of CNPC
E&D respectively.

As CNODC is a wholly-owned subsidiary of China National Petroleum Corporation,
the controlling shareholder of the Company, CNODC is a connected person of the
Company pursuant to the Shanghai Listing Rules and the Hong Kong Listing Rules.
As CNODC holds 50% of the shares of CNPC E&D, CNPC E&D is also a connected
person of the Company under the Hong Kong Listing Rules. Therefore, the Capital
Injection by the Company and CNODC into CNPC E&D constitutes a connected
transaction of the Company under the Shanghai Listing Rules and the Hong Kong
Listing Rules.

                                      -1-


1.   SUMMARY OF CONNECTED TRANSACTION

     PetroChina Company Limited (the "COMPANY") convened an extraordinary
meeting of the 3rd Session of its board of directors on 27 December 2007 at
which the resolution in respect of the "Capital Injection Agreement Concerning
CNPC Exploration and Development Company Limited" was considered and approved.
On 27 December 2007, the Company entered into the "Capital Injection Agreement
Concerning CNPC Exploration and Development Company Limited" with China National
Oil and Gas Exploration and Development Corporation ("CNODC") and CNPC
Exploration and Development Company Limited ("CNPC E&D") pursuant to which the
Company and CNODC, as shareholders of CNPC E&D, shall inject capital in the
aggregate amount of RMB16 billion (approximately HK$16,944 million) into CNPC
E&D. The Company and CNODC shall each make a capital injection of RMB8 billion
(approximately HK$8,472 million) in cash, payable in one lump sum (the "CAPITAL
INJECTION"). Upon completion of the Capital Injection, the Company and CNODC
will continue to hold 50% of the shares of CNPC E&D respectively. The funds
required to finance the Capital Injection by the Company will come from its
internal resources.

     As CNODC is a wholly-owned subsidiary of China National Petroleum
Corporation, the controlling shareholder of the Company, CNODC is a connected
person of the Company pursuant to the Listing Rules of the Shanghai Stock
Exchange (the "SHANGHAI LISTING RULES") and the Listing Rules of The Stock
Exchange of Hong Kong Limited (the "HONG KONG LISTING RULES"). As CNPC E&D is a
non wholly-owned subsidiary of the Company and CNODC holds 50% of the shares of
CNPC E&D, CNPC E&D is also a connected person of the Company under the Hong Kong
Listing Rules. Therefore, the Capital Injection by the Company and CNODC into
CNPC E&D constitutes a connected transaction of the Company under both the
Shanghai Exchange Listing Rules and the Hong Kong Listing Rules.


2.   REGULATORY REQUIREMENTS

     Pursuant to the Shanghai Listing Rules, the amount of the Capital Injection
is less than 5% of the latest audited net asset value of the Company. Pursuant
to the Hong Kong Listing Rules, the applicable percentage ratios for the Capital
Injection are more than 0.1% but less than 2.5%. Accordingly, the Capital
Injection shall comply with the reporting and public announcement requirements
under Rule 10.2.4 of the Shanghai Listing Rules and Rule 14A.32 of the Hong Kong
Listing Rules respectively, but shall not require the approval of the
independent shareholders of the Company. Therefore, the Capital Injection will
become effective upon approval of the board of directors of the Company.

5.   PURPOSE OF THE CAPITAL INJECTION

     (i)  Summary

     At present, CNPC E&D intends to co-operate with two state-owned development
companies respectively in the Republic of Kazakhstan ("KAZAKHSTAN") and the
Republic of Uzbekistan ("UZBEKISTAN") and invest in the development and
construction of a Central Asia

                                      -4-


- China natural gas pipeline project for the transmission of natural gas
purchased by China from the Republic of Turkmenistan ("TURKMENISTAN"). For this
purpose, CNPC E&D has established a wholly-owned subsidiary, Trans-Asia Gas
Pipeline Company Limited ("TRANS-ASIA GAS"), which acts as the platform for
undertaking this natural gas pipeline development and construction project. As
CNPC E&D requires substantial funding to undertake the project, each of the
Company and CNODC, as shareholders of CNPC E&D, proposes to inject additional
capital of RMB8 billion (approximately HK$8,472 million) into CNPC E&D, totaling
RMB16 billion (approximately HK$16,944 million) to satisfy such funding
requirement. During the year prior to the Capital Injection, the Company and
CNODC have not made any capital contribution into CNPC E&D.

     (ii) Brief introduction of the Central Asia - China natural gas pipeline
          project

     The Central Asia - China natural gas pipeline stretches from Gedaim, which
is at the border of Turkmenistan and Uzbekistan, runs across Uzbekistan and
Kazakhstan and reaches Khorgos in China. The pipeline will be 1,818 km long, of
which 525 km will run through Uzbekistan and 1,293 km will run through
Kazakhstan. The diameter of the pipeline will be 1,067 mm. A dual-laid pipeline
will be installed. The designed gas transmission capacity will be 30 billion
cubic meters per annum, which is capable to be increased to 40 billion cubic
meters per annum. The total project investment is estimated to be US$7.31
billion.

     The target markets for gas transmitted through the Central Asia - China
natural gas pipeline into China include the Central-western provinces such as
Xinjiang, Gansu, Ningxia, Shaanxi and Sichuan, the Central-southern provinces
such as Henan, Anhui, Hubei, Hunan and Jiangxi, the Yangtze River Delta region
including Shanghai and the Jiangsu and Zhejiang provinces, and the South-eastern
coastal provinces such as Guangdong and Guangxi.

     On 8 November 2007, CNPC E&D established Trans-Asia Gas, a wholly-owned
subsidiary, to undertake the above project. Trans-Asia Gas will set up a
Chinese-Uzbekistan equity joint venture and a Chinese-Kazakhstan equity joint
venture with the state-owned development company of each of Uzbekistan and
Kazakhstan for the purposes of undertaking the project. Applications for
obtaining the approval and confirmation from relevant governmental authorities
in China are currently underway. If the formation of these two joint ventures
shall trigger any compliance requirements under the Shanghai Listing Rules
and/or Hong Kong Listing Rules, the Company will comply with such requirements
at appropriate times.

                                      -5-


6.   KEY CONTENTS OF THE CAPITAL INJECTION AGREEMENT AND CONSIDERATION

     (i)  Key contents of the agreement

     1. The agreement concerning the Capital Injection as a connected
transaction, namely the "Capital Injection Agreement Concerning CNPC Exploration
and Development Company Limited", will be entered into between the Company,
CNODC and CNPC E&D.

     2. The registered capital of CNPC E&D will be increased by RMB16 billion
(approximately HK$16,944 million), with the Company and CNODC each injecting
RMB8 billion in cash. Within 7 working days from the signing of the capital
injection agreement, the Company and CNODC shall pay their respective capital
contribution in full in one lump sum into an account designated by CNPC E&D.

     3. The agreement will be executed after each party has obtained its
internal approval and will become effective upon signing.

     (ii) Consideration

     For the Capital Injection, the Company and CNODC will each inject RMB8
billion (approximately HK$8,472 million) payable in one lump sum in cash. Upon
the Capital Injection, the percentage of equity interest of the Company and
CNODC in CNPC E&D will remain to be 50%: 50%.


7.   EFFECT OF THE TRANSACTION ON THE COMPANY

     (i)  Due to the continuous rapid economic growth in China, there is
          substantial demand for energy resources. The demand for clean energy
          is particularly strong. The Capital Injection will increase the
          international reach of the business of the Company through the
          overseas operations of CNPC E&D. It will also increase the market
          share of the Company in the domestic natural gas market. This presents
          new opportunities to boost the financial performance of the Company.

     (ii) The investment resulting from the Capital Injection is an important
          strategic project for the supply of oil and gas to China. It will also
          safeguard a constant supply of natural gas to China. The Company's
          investment in this project represents an important opportunity for the
          Company, as a reputable international and domestic company, to
          strengthen its corporate image as a socially responsible company.

                                      -6-


     (iii) The Company's investment in this project will further enhance its
           collaborations with state-owned development companies in Central-
           Asian countries, which will further strengthen the development of the
           Company's business in this region.


8.   DIRECTORS' OPINION

     The Company convened an extraordinary meeting of the 3rd Session of its
board of directors by way of written resolutions on 27 December 2007. Eleven
directors participated in the meeting. The Chairman of the Company, Mr. Jiang
Jiemin, and certain directors of the Company, namely Mr. Duan Wende, Mr. Zhou

aforesaid views.
