                                  ANNOUNCEMENT

This announcement is made at the request of The Stock Exchange of Hong Kong
Limited.

The board of directors (the "BOARD") of PetroChina Company Limited (the
"COMPANY") has noted recent press comments and confirms that Zhong You Kan Tan
Kai Fa Company Limited ("NEWCO"), a 50:50 joint venture between the Company and
China National Oil and Gas Exploration and Development Corporation ("CNODC", a
subsidiary of the Company's parent company, China National Petroleum
Corporation) and a subsidiary of the Company, is currently actively considering
exercising the priority right granted to it by CNODC to acquire certain non-PRC
assets held by CNODC or its subsidiaries, in respect of CNODC's interest in
PetroKazakhstan Inc. which was recently acquired by it. The Company's
acquisition of its interest in Newco was announced on 10 June 2005 and fuller
details of this acquisition (including details of Newco's priority right) were
included in the circular to the Company's shareholders dated 30 June 2005 in
connection with the acquisition.

The Company has approached CNODC to discuss the possible acquisition of its
interests in PetroKazakhstan Inc. However, no formal decision has been reached
by the Board and any such acquisition is subject to, amongst other things,
decisions relating to the structure, size, timing and terms of the acquisition,
conclusion of negotiations with CNODC, satisfactory completion of due diligence,
the signing of definitive agreements and the requirements under relevant laws
and regulations. If the acquisition proceeds, the Company will comply with all
applicable Listing Rule requirements.

In the meantime, investors should exercise caution in dealing in securities of
the Company.



                                                  By Order of the Board
