             ANNOUNCEMENT ON FINANCIAL SUPPORT MEASURES BY THE STATE
               TO ENSURE SUPPLY OF CRUDE OIL AND REFINED PRODUCTS



PetroChina  Company  Limited  (the  "Company")  and all  members of its board of
directors warrant the truthfulness, accuracy and completeness of the information

Listing of Securities on The Stock Exchange of Hong Kong Limited and Rule 11.8.3
of the Listing Rules of the Shanghai Stock Exchange.

Since the  beginning  of this year,  international  crude oil  prices  have been
surging,  while  domestic  refined  product  prices  have been  subject to tight
control  in  the   People's   Republic  of  China  (the   "PRC").   Under  these
circumstances,  the Company has upheld the principle of scientific organization,
strengthened  management and implemented  measures  pro-actively to endeavour to
ensure supply of refined products in the market.

Recently,  the Company has been  notified by the  Ministry of Finance of the PRC
that in order to ensure supply of crude oil and refined  products in the market,
the following financial support measures will be implemented:

1.   Commencing  from 1 April  2008,  the  Ministry  of  Finance of the PRC will
     provide  appropriate  level of subsidy against losses sustained as a result
     of the refining and  processing of imported  crude oil. The subsidy will be
     granted and settled on a monthly basis.

2.   Refund of the full amount of the value-added tax levied on imported refined
     products will be implemented in the second quarter of 2008.


                                                    By Order of the Board
                                                  PETROCHINA COMPANY LIMITED
