       Risk Factors
       Risks Related to Government Regulation, page 11

   1.                                                   Your operations in
China currently contribute the large majority of your revenue. Expand
                                                        the disclosure under
this risk factor to also provide specific and prominent disclosure
                                                        about the legal and
operational risks associated with operating in China. Your disclosure
                                                        should make clear
whether these risks could result in a material change in your operations
                                                        and/or the value of
your ADSs or could significantly limit or completely hinder your
                                                        ability to offer or
continue to offer securities to investors and cause the value of such
                                                        securities to
significantly decline or be worthless.
   2.                                                   We note your disclosure
that your operations, like those of other People   s Republic of
                                                        China oil and gas
companies, are subject to extensive regulations and control by the

         People   s Republic of China government. Revise the disclosure under
this risk factor to
         also provide specific and prominent disclosure about the risks that
operating in China
         poses to investors. In particular, describe the regulatory, liquidity,
and enforcement risks.
         For example, specifically discuss risks arising from the legal system
in China, including
         risks and uncertainties regarding the enforcement of laws and that
rules and regulations in
         China can change quickly with little advance notice; and the risk that
the Chinese
         government may intervene or influence your operations at any time, or
may exert more
         control over foreign investment in China-based issuers, which could
result in a material
         change in your operations and/or the value of your ADSs.
3.       You disclose that because your operations are subject to extensive
regulations and control
         by the People   s Republic of China, you may face significant
constraints on your ability to
         implement your business strategies, to develop or expand your business
operations or to
         maximize your profitability. Given the Chinese government   s
significant oversight and
         discretion over the conduct of your business, please revise to provide
specific and
         prominent disclosure highlighting the risk that the Chinese government
may intervene or
         influence your operations at any time, which could result in a
material change in your
         operations and/or the value of your ADSs.
Risks Related to Controlling Shareholder, page 13

4.       As of December 31, 2020, China National Petroleum Corporation was your
controlling
         shareholder and beneficially owned approximately 80.41% of your share
capital. Please

your filing and to
         provide specific disclosure that identifies who controls China
National Petroleum
         Corporation.
Risks Related to Climate Change, page 15

climate change that may
         affect your business, financial condition, and results of operations,

burdens, market trends
         that may alter business opportunities, credit risks, or technological
changes.
6.       Disclose any material litigation risks related to climate change and
the potential impact to
         the company.
