     PetroChina Company Limited (the "Registrant") is furnishing under the cover
of Form 6-K the Registrant's announcement with respect to its placing of new H
shares and resumption of trading.



The Stock Exchange of Hong Kong Limited (the "STOCK EXCHANGE") takes no
responsibility for the contents of this announcement, makes no representation as
to its accuracy or completeness and expressly disclaims any liability whatsoever
for any loss howsoever arising from or reliance upon the whole or any part of
the contents of this announcement.

The securities have not been registered under the United States Securities Act
of 1933, as amended (the "U.S. SECURITIES ACT") and may not be offered or sold
in the United States or to U.S. persons unless the securities are registered
under the U.S. Securities Act, or an exemption from the registration
requirements of the U.S. Securities Act is available. This announcement does not
constitute an offer of any securities for sale.

In connection with the Placing, Goldman Sachs (Asia) L.L.C. (the "STABILIZING
MANAGER"), and/or its affiliates and agents, on behalf of the Underwriters, may
over-allocate or effect any other transactions with a view to stabilizing or
maintaining the market price of the H Shares (as defined below) at a level
higher than that which might otherwise prevail for a limited period commencing
from the date of this announcement. The stabilizing action which may be taken by
the Stabilizing Manager may include primary and ancillary stabilizing action
such as purchasing or agreeing to purchase any of the H Shares, exercising the
Managers' Option (as defined below), stock borrowing, establishing a short
position in the H Shares, liquidating long positions in the H Shares or offering
or attempting to do any such actions. Any market purchases will be effected in
compliance with all applicable laws and regulatory requirements, including the
Securities and Futures (Price Stabilizing) Rules made under the Securities and
Futures Ordinance (Cap. 571 of the Laws of Hong Kong). However there is no
obligation on the Stabilizing Manager to conduct any such stabilizing activity,
which if commenced, may be discontinued at any time. Any such stabilizing
activity is required to be brought to an end after a limited period which begins
on the date after the Purchase Price is announced and ends on the 30th day after
the Completion Date. The stabilizing period is expected to expire on 15 October
2005 and after this date, no further stabilizing action may be taken. Demand for
the H Shares, and therefore their price, could fall. The number of H Shares
being offered in the Placing may be increased by up to an aggregate of
351,648,000 additional H Shares through the exercise of the Managers' Option
granted to the Stabilizing Manager on behalf of the Underwriters by the Company
and the Selling Shareholder, exercisable by the Stabilizing Manager on behalf of
the Underwriters and after consultation with the Underwriters, to, amongst other
things, cover over-allocations in the Placing.

--------------------------------------------------------------------------------
On 31 August 2005, PetroChina Company Limited (the "COMPANY") entered into an
underwriting agreement (the "UNDERWRITING AGREEMENT") with Citigroup Global
Markets Hong Kong Futures and Securities Limited, Deutsche Bank AG, Hong Kong
Branch and Goldman Sachs (Asia) L.L.C. (the "UNDERWRITERS"), as joint
bookrunners and underwriters, in relation to the placing (the "PLACING") of an
aggregate of 3,164,834,000 new overseas-listed foreign-invested shares of
RMB1.00 each ("H SHARES") in the capital of the Company (the "INITIAL PLACING
SHARES") at a price of HK$6.00 per Initial Placing Share (the "PURCHASE PRICE").

The Initial Placing Shares comprises of (1) 2,877,121,818 H Shares (the "NEW
SHARES") to be allotted and issued by the Company in connection with the
Placing, and (2) 287,712,182 H Shares (the "NSSF SHARES") to be allotted and
issued by the Company upon the conversion of the same number of existing
domestic legal person shares by the National Council for the Social Security
Fund (the "NSSF").

In addition, an option (the "MANAGERS' OPTION") has been granted to the
Stabilizing Manager on behalf of the Underwriters pursuant to which the
Stabilizing Manager may require the Company to issue up to an additional
319,680,000 H Shares and NSSF to sell up to an additional 31,968,000 H Shares
(together, the "OPTION SHARES" and, together with the Initial Placing Shares,
the "PLACING SHARES") at the Purchase Price as further described under the
heading "MANAGERS' OPTION" below.

The Initial Placing Shares represent approximately 18.00% of the existing issued
H share capital of the Company and approximately 15.25% of the issued H share
capital of the Company as enlarged by the issue of the Initial Placing Shares.
If the Managers' Option is exercised in full, the Placing Shares represent
approximately 20.00% of the existing issued H share capital of the Company and
approximately 16.67% of the issued H share capital of the Company as enlarged by
the issue of the Placing Shares.

The net proceeds of the Placing of new H Shares by the Company will be
approximately HK$17,002 million (and HK$18,891 million if the Managers' Option
is exercised in full) after deducting the commission and expenses of the
Placing. The Company intends to use the net proceeds from the Placing of the new
H Shares by the Company for its business development, including the funding of
any domestic and/or international acquisitions that may be made by the Company.
As at the date of this announcement, the Company has not entered into any
agreement in relation to future acquisitions. In the event the Company enters
into any such agreements, it will comply with the relevant requirements under
the Rules Governing the Listing of Securities on The Stock Exchange of Hong Kong
Limited (the "LISTING RULES").

Trading in the H Shares on the Stock Exchange was suspended from 9:30 a.m. on 31
August 2005 at the request of the Company, and application has been made to the
Stock Exchange to resume trading in the H Shares with effect from 9:30 a.m. on 1
September 2005. Trading in the Company's American Depository Shares (the "ADSS")
on the New York Stock Exchange, Inc. (the "NYSE") was suspended from 9:30 a.m.

has been made to resume trading in the ADSs with effect from 9:30 a.m. (New York

(i)   a discount of approximately 2.4 per cent. to the ex-dividend closing price
      of approximately HK$6.15 per H Share on the Stock Exchange on 30 August
      2005 (the Last Dealing Date), being the date immediately preceding the
      date of the Underwriting Agreement and the last day of trading in the H
      Shares on the Stock Exchange prior to the date of this announcement; (note
      1) (note 3)

(ii)  a discount of approximately 4.0 per cent. to the average ex-dividend
      closing price of approximately HK$6.25 per H Share for the last five
      trading days on the Stock Exchange up to and including the Last Dealing
      Date; (note 2) (note 3)

      HK$6.30 per H Share on the Stock Exchange on the Last Dealing Date;

(v)   a discount of approximately 6.3 per cent. to the average last closing
      price of approximately HK$6.40 per H Share for the last five trading days

      on the Stock Exchange up to and including the Last Dealing Date.

Notes: 

(1)   The closing price for 30 August 2005 is an ex-dividend price, after
      deducting the HK$0.151333 interim dividend from the cum-dividend closing
      price of HK$6.30 on that day.

(2)   The average closing price is an ex-dividend average closing price,
      calculated by deducting the HK$0.151333 interim dividend from the
      cum-dividend closing prices for the most recent four trading days, being
      the four trading days since the declaration of the interim dividend.

(3)   The Board declared an interim dividend of RMB0.157719 (inclusive of
      applicable tax) for the six months ended 30 June 2005 on the basis of 45%
      of the net profit for the period. Dividends payable in respect of H Shares
      shall be paid in Hong Kong dollars. The amount of Hong Kong dollars
      payable shall be calculated on the basis of the average closing exchange
      rate between Renminbi and Hong Kong dollars published by the People's Bank
      of China during the week before the Board declares the dividend on 24
      August 2005, which is RMB1.0422 = HK$1.00. Accordingly, the amount of the
      interim dividend payable per H Share will be HK$0.151333. 

The Purchase Price was agreed after arm's length negotiation between the Company
and the Underwriters, and was determined by reference to, amongst other things,
the recent trading prices of the H Shares. The effective net Purchase Price is
approximately HK$5.91 per H Share.

part of the Placing, the allocation of the NSSF Shares from China National
Petroleum Corporation ("CNPC") to the NSSF in accordance with applicable laws
and regulations of the PRC. The NSSF has entrusted the Company to effect a sale
