PRESS RELEASE

              PETROCHINA'S 2005 NET PROFIT RISES 28.4% YEAR-ON-YEAR
                      TO A RECORD HIGH OF RMB133.36 BILLION

20 March 2006, Beijing - PetroChina Company Limited ("PetroChina" or the
"Company," SEHK stock code 0857; NYSE symbol PTR) announced today it recorded a
net profit of RMB133.36 billion for the year ended December 31, 2005,
representing an increase of 28.4 percent from the previous year. This marks yet
another record high in the Company's earnings since its initial public offering.

For the year ended December 31, 2005, the Company's turnover reached RMB552.23
billion, representing an increase of 39 percent from 2004. The basic and diluted
earnings per share was RMB0.75, representing an increase of approximately
RMB0.16 from 2004. The Company's Board of Directors recommended a final dividend
of RMB0.180325 per share for 2005. Including the interim dividend of RMB0.157719
per share, the dividend for 2005 will be RMB0.338044 per share.

Mr. Chen Geng, Chairman of PetroChina said, "2005 was filled with

                                       1


opportunities and challenges. Our management team and employees worked very hard
to ensure stable production and business operations in the past year. Combined
with enhanced management and a series of M&A initiatives, our efforts led to a
strong growth in earnings, which was the highest since our listing, and laid a
solid foundation for the Company's long-term development."

EXPLORATION AND PRODUCTION

In 2005, the Company continued to place exploration a priority, increasing
investments in both oil and gas exploration. The Company reached strategic
milestones in exploring seven areas, including the Jidong tidal and shallow
water areas in the Bohai Bay Basin, Xujiaweizi in the northern Songliao Basin,
Changling in the southern Songliao Basin, Jiyuan in the Erdos Basin, Tazhong in
the Tarim Basin, Chuanzhong in the Sichuan Basin, and the northwestern rim of
the Junggar Basin. According to independent reserves assessment, the Company
added 864 million barrels to its crude oil reserves, and 4,200 billion cubic
feet to its natural gas reserves in 2005. The Company realized a replacement
ratio of 1.04 for crude oil reserves, 3.14 for natural gas reserves, and 1.49
for oil and gas reserves in 2005.

In 2005, the Company's domestic crude oil output recorded the highest growth in
recent years, and its natural gas output maintained rapid growth. Its overseas
oil and gas output also grew rapidly. Last year, PetroChina saw its domestic and
overseas oil and gas output reached

                                       2


an aggregate 1.01 billion barrels of oil equivalent, an increase of 5.1 percent
from 2004. Crude oil output reached 823 million barrels, representing an
increase of 1.1 percent from a year earlier. Output of marketable natural gas
reached 1,120 billion cubic feet, representing a rise of 27.8 percent from 2004.

In 2005, the Company's exploration and production segment recorded an operating
profit of RMB208.08 billion, representing an increase of RMB77.87 billion, or
59.8 percent, from the previous year. The increase in operating profit was
mainly due to higher oil and gas prices and increased sales volumes.

REFINING AND MARKETING

In 2005, the growth of the Company's crude oil refining volume and refined
products output were above the industry average due to optimal resources
allocation and strong management of its refining business. The Company processed
752.3 million barrels of crude oil, representing an increase of 6 percent from
2004.

Responding to market changes in 2005, the Company boosted its quality efforts in
marketing and expanded its retail market share. It sold 75.981 million tons of
refined products, representing a rise of 13.4 percent, among which 38.12 million
tons were retail sales. The number of service stations totaled 18,164 units last
year, representing an increase of 4.4 percent from 2004. Among the total, the
number of

                                       3


service stations owned by the Company increased 1,869 units, or 13.3 percent
from the previous year.

In 2005, the Company's refining and marketing segment recorded an operating loss
of RMB19.81 billion due to the control of refined products prices by government
authorities.

CHEMICALS AND MARKETING

In 2005, the Company ran its major chemicals facilities at full capacity as it
seized market opportunities and optimized its product mix. The Company produced
13.15 million tons of chemical products, representing a rise of 3.3 percent from
2004. It produced 1.89 million tons of ethylene, 2.76 million tons of synthetic
resin, 0.28 million tons of synthetic rubber, and 3.58 million tons of urea in
2005. The sales volume of chemical products amounted to 14.27 million tons,
representing an increase of 9.6 percent from 2004.

In 2005, the chemical and marketing segment recorded an operating profit of
RMB3.28 billion, RMB4.38 billion lower than a year earlier. Changes in raw
material prices drove the profit lower by RMB3.176 billion, while an increase in
depreciation and depletion expenses also pulled down the profit.

NATURAL GAS AND PIPELINE

In 2005, the construction of major oil and gas pipelines proceeded smoothly. The
Second Shaanxi-Beijing Pipeline was put into operation, lifting substantially
the Company's capacity to supply natural gas to Beijing and the northern China
region. The Company completed the construction of the Hunan Xiangtan branch of
the Zhongxian-Wuhan Pipeline, marking the full operation of the Zhongxian-Wuhan
Pipeline, which comprises one trunk and three branches. In addition,
construction on the trunk line of the Jining connection line was finished,
linking the West-East Gas Pipeline with the Second Shaanxi-Beijing Pipeline.
This gas pipeline is nearly ready for commercial operation and will help balance
distribution between the Second Shaanxi-Beijing Pipeline and the West-East Gas
Pipeline, ensuring a stable supply to the market. By the end of 2005, the crude
oil pipeline between Alashankou and Dushanzi has been completed.

In 2005, the natural gas and pipeline business recorded an operating profit of
RMB3.18 billion, representing an increase of 25.6 percent from 2004, lifted by
growth in natural gas sales volume and prices.

CAPITAL MARKET OPERATIONS

In 2005, the Company made achievements in the capital market operations. In June
2005, the Company announced that it had signed an Acquisition and Transfer
Agreement with its parent China National

                                       5


Petroleum Corporation, paying RMB20.7 billion to acquire certain overseas
assets. Through establishing a joint venture with its parent company, the
Company will steadily increase the scope and potential of its overseas oil and
natural gas resources and further enhance corporate value. In September 2005,
the Company completed its first ever H share placement after its listing in
2000, raising net proceeds of HKD18.9 billion to fund corporate development. In
October 2005, the Company began to acquire the outstanding shares of Jilin
Chemical, Jinzhou Petrochemical and Liaohe Jinma, with an aim to delist its
three listed subsidiaries. The acquisitions, which have been completed, are
significant to optimizing the Company's management, fully implementing the
Company's business strategy as well as reducing and regulating the connected
transactions.

FUTURE PROSPECTS FOR 2006

Looking ahead, the Company anticipates a positive business environment in 2006
as global crude oil prices are expected to remain high while domestic demand for
oil, gas and petrochemical products stay strong. Nevertheless, uncertainties may
exist and unforeseeable factors may have an impact on the Company. In the new
year, the Company will actively respond to market changes and make efforts to
bolster its reserves by enhancing domestic exploration. It will push forward the
construction of key refining and chemical projects to widen its business scale,
while increasing quality marketing efforts and improving operational
efficiencies to expand market share. It will also

                                       6


adhere to its international strategy by further developing overseas operations,
while cooperating more extensively with foreign companies in domestic projects
and growing its foreign trade volume. In addition, it will enhance health,
safety and environmental protection efforts, and continue to uphold its
corporate social responsibility. The Company management will endeavor to achieve
sustainable, effective and rapid growth for the long term.
