Having set up the CCUS industry chain, we will be able to accelerate the provision of cleaner energy and the establishment of a scalable carbon industry, facilitate the transition of the industry towards a green and low-carbon future, and help achieve the carbon emission peak and carbon neutrality goals. Conducting research on advanced CCUS technologies We developed technologies and equipment related to the effective capture, transportation, injection, and storage of carbon dioxide. We deployed new and advanced carbon capture technologies such as the use of organic amine absorbents and solid absorbents, developed technologies for long-range and large-capacity carbon transportation and storage, data simulation, integrated air monitoring, and succeeded in capturing, utilizing and storing low concentrations of carbon dioxide. Moreover, we participated in the global research projects on direct air carbon capture and storage (DACCS), bioenergy with carbon capture and storage (BECCS), and ocean carbon sequestration. We also established and perfected a standardized system for CCUS processes. Making plans to create a CCUS regional industrial center With the aim to promote a cleaner use of fossil fuel energies and upgrade the industry chain to reach net-zero emissions, we carried out strategic planning to construct CCUS regional industrial centers in priority locations such as Songliao, Junggar, Ordos, Tarim, Hainan. We also participated in the construction planning of OGCI’s global CCUS regional industrial center and explored the regional CCUS commercialization model. Applying CCUS technologies to improve recovery rate and build a “near-zero” emission demonstration zone for the petroleum and petrochemical industry Leveraging the strengths of the integrated oil field and refinery businesses, we integrated the resources of different oil and gas fields and refining companies, such as those in Xinjiang, Changqing, Daqing, Jilin, and the Bohai Economic Rim, and applied carbon capture, utilisation and storage and enhanced oil recovery (CCUS-EOR) technologies to utilize the carbon produced and captured by refining companies on oil and gas extraction. We also increased oil recovery rates through carbon dioxide flooding and built a “near-zero” emission demonstration zone for the petroleum and petrochemical industry. In 2022, our CCUS project at Jilin Oil Field had a carbon injection capacity of 800,000 tons, and an annual oil production capacity of 200,000 tons. At present, an accumulative total of 2.77 million tons of carbon dioxide has been injected into the oil field under the project, making it the largest carbon injection in China. The recovery rate of crude oil was increased by more than 25%, which is the equivalent to the discovery of a new oil field of the same scale. __

As of the end of 2022, over 1,000 companies have completed registration with over 30% being local companies. We give priority consideration to local suppliers/contractors for raw materials, oil products, consumables, stationery, support services and local security, with particular procurement projects requiring at least 50% local bidders. Over the past few years, local suppliers/ contractors have gradually expanded from providing minor services such as support services, stationery supply and material supply to participation in minor construction works and are actively participating in subcontractor work with large contractors. In Rumaila, our localized procurement policy has extensively helped the development of local small and medium-sized enterprises, including Etihad Al Basra for Contracting Trading and Custom (EBCC). Our project has provided EBCC with specialized training including key site position training, regular system training, ISO management system and inspection system establishment, helping EBCC achieve international standards from business, management to compliance. After over a decade, EBCC has grown from an ordinary local company into one of Iraq’s leading integrated site service companies. __

2023 Derivatives Framework Agreement

The Board is pleased to announce that, on March 29, 2023, the Company entered into the 2023 Derivatives Framework Agreement with CNPC Finance, pursuant to which CNPC Finance agreed to provide currency derivatives services to the Group in 2023. The principal terms of the 2023 Derivatives Framework Agreement are as below.

Date:	March 29, 2023
Parties:	(a) the Company
	(b) CNPC Finance
Term:	Until December 31, 2023
Subject matter:	CNPC Finance agreed to provide currency derivatives services to the Group, and the types of derivatives include forward settlements and sales of foreign exchange, forward purchase and sales of foreign exchange, foreign exchange<br>swaps, currency swaps, interest swaps

Pricing Policy and Enforcement

For transactions entered into between the Group and CNPC Finance pursuant to the 2023 Derivatives Framework Agreement, the terms of the transactions, fees charged and other relevant transaction conditions should comply with the relevant requirements of regulatory authorities, with reference to services of the similar size and type offered by CNPC Finance to third parties with the same credit rating level and services of the similar size and type offered to the Group provided by independent third party financial institutions (the “Third Party Financial Institutions”), and such transactions shall be conducted on normal commercial terms or better for the Group.

Before the Group enters into specific agreements with CNPC Finance for each transaction under the 2023 Derivatives Framework Agreement, the terms offered or fees charged by CNPC Finance and other relevant transaction conditions shall be compared with those for transactions of the similar size and type offered by Third Party Financial Institutions. The Group shall have the discretion to enter into transactions with CNPC Finance only if the terms offered or fees charged by CNPC Finance or other relevant transaction conditions are the same or better than those offered by Third Party Financial Institutions. The Group may also additionally or alternatively seek Third Party Financial Institutions to conduct relevant transactions as it deems appropriate.

Historical Amount and Historical Annual Cap

The 2022 Annual Cap is US$7.500 billion. For the year ended December 31, 2022, the amount of currency derivatives transactions between CNPC Finance and the Group amounted to US$3.984 billion.

Proposed Annual Cap and Determination Basis

The Board considered and recommended that, for the year ended December 31, 2023, the 2023 Annual Cap shall not exceed US$6.500 billion. Based on the central parity rate of USD to RMB announced by the People’s Bank of China on 28 March 2023, US$1 = RMB6.8749, US$6.500 billion is equivalent to approximately RMB44,686.850 million (for indicative purpose only and the 2023 Annual Cap is US$6.500 billion).

The 2023 Annual Cap is determined after taking into account the following factors:

(1)	the estimated settlement amount of international trade conducted by the Group for the year of 2023;<br>
(2)	CNPC Finance’s experience in foreign exchange business, and the Company’s belief that the prices and<br>quality of the services provided by CNPC Finance are not less favorable than comparable levels or conditions in the market;
---	---

2

(3)	the realization of the reduction and hedging of exchange risk through the relevant financial services provided<br>to the Group by CNPC Finance and other Third Party Financial Institutions; and
(4)	fluctuation in the Renminbi exchange rates and other external factors in the context of global trade<br>uncertainty.
---	---

Risk Management and Internal Control Measures

The main risks associated with currency derivative transactions include market risk, liquidity risk, margin risk, compliance risk and counterparty risk. To effectively address the above-mentioned risks and ensure that the pricing for such transactions is consistent with the above-mentioned pricing policy, the Company takes the measures set out below:

(1)	The Company formulated relevant management policy and established cross-department management and cooperation<br>system, strengthened the review of business qualification and annual planning, clarified the rights and responsibilities of headquarters, specialized companies and business entities.
(2)	The Company will strictly enforce a series of measures, including connected transaction management methods,<br>internal control management handbook and internal control assessment management methods to ensure that connected transactions are conducted in accordance with the 2023 Derivative Framework Agreement and the above-mentioned pricing policy. The<br>Company’s external auditors shall conduct an interim review and a year-end audit on the Company’s internal control measures. Meanwhile, the Company’s finance department and legal and enterprise<br>reform department, the audit committee of the Board and the supervisory committee of the Company shall, from time to time, each conduct internal assessments, supervision and examination on the internal control measures and the financial information<br>of the Company, in order to ensure that the internal control measures in respect of connected transactions remain complete and effective. Furthermore, they convene meetings twice a year to discuss and assess the implementation of connected<br>transactions.
---	---
(3)	The independent non-executive Directors shall conduct annual review on<br>the continuing connected transactions and provide annual confirmations in the annual reports of the Company on whether the continuing connected transactions have been entered into (i) in the ordinary and usual course of business of the Group;<br>(ii) on normal commercial terms or better; and (iii) according to the relevant agreements governing them on terms that are fair and reasonable and in the interest of the Company and the Shareholders as a whole.
---	---
(4)	The audit committee of the Board shall conduct review on the annual report and interim report which include the<br>disclosure and analysis of the execution of the continuing connected transactions.
---	---
(5)	The external auditors of the Company shall report on the continuing connected transactions of the Company every<br>year and issue a letter to the Board in respect of the continuing connected transactions of the Company in accordance with the regulatory rules of domestic and overseas places where the Company is listed.
---	---
(6)	The supervisory committee of the Company shall supervise the continuing connected transactions and review the<br>annual report and interim report which include the disclosure and analysis of the execution of the continuing connected transactions every year. The supervisory committee of the Company shall also review whether the connected transactions between<br>the Company and connected persons comply with the regulatory requirements of domestic and overseas places where the Company is listed, whether the prices are fair and reasonable and whether there is any act which is detrimental to the interests of<br>the Company and the Shareholders.

Reasons for and Benefits of the Entering Into of the 2023 Derivatives Framework Agreement

The Company’s international trade business process including settlement involves the exchange of RMB, USD, EUR, GBP and other currencies and is exposed to high level of exchange rate risk. Therefore, the Company intends to actively manage exchange risk and reduce exchange loss through the conduct of currency derivatives transactions.

CNPC Finance is a subordinated financial enterprise of CNPC, the controlling shareholder of the Company, which focuses on serving the CNPC and has strong financial capability to provide efficient financial services to the Group’s domestic and overseas operations. Details of CNPC Finance are set out below.

(1)	CNPC Finance has rich experience in the foreign exchange business. CNPC Finance is the internal settlement,<br>fund raising and financing and capital management platform of CNPC. CNPC Finance has been providing deposit, loan, settlement and other financial services to the Group for many years and has established a comprehensive and matured cooperation<br>mechanism with the Company. The Company considers that due to familiarity with the business and operation of the Group, the service provided by CNPC Finance is generally no less favourable to the comparable level and conditions in the market in<br>terms of price and quality, resulting higher efficiency, more convenience and lower transaction costs.
(2)	The transactions with CNPC Finance could lower the costs of the Group because of CNPC Finance’s various<br>mechanisms, such as its efficient internal settlement, and its convenient, timely and efficient process of foreign exchange derivative business. Furthermore, CNPC Finance’s utilization of its status as member of the China Foreign Exchange Trade<br>System (中國外匯交易中心) to develop businesses in the settlement, sales and conversion of foreign currency could save the Group a considerable<br>amount in foreign exchange costs.
---	---
(3)	CNPC Finance is under the supervision of the China Banking and Insurance Regulatory Commission as a major<br>domestic non-bank financial institution and has met the regulatory requirements as determined by regulatory indicators over the years. As at the end of 2022, CNPC Finance has total assets of<br>RMB528,334 million and achieved a revenue of RMB13,302 million and a net profit of RMB6,312 million, which is in a leading position among domestic counterparts. In 2013, CNPC Finance (HK) Limited, a wholly-owned subsidiary of CNPC<br>Finance, obtained the sovereign rating assigned by an international rating agency. This is currently the highest credit rating obtained by domestic financial institutions.
---	---

For the reasons set out above, the Company considers that the currency derivatives transactions under the 2023 Derivatives Framework Agreement are beneficial to the on-going development of the Group.

The Board (including the independent non-executive Directors) considers that the currency derivatives transactions under the 2023 Derivatives Framework Agreement are in the ordinary and usual course of business of the Group, are on normal commercial terms or on terms no less favourable than those of Third Party Financial Institutions, and that the terms and 2023 Annual Cap are fair and reasonable and in the interests of the Company and all Shareholders as a whole.

Listing Rules Implications

As at the date of this announcement, CNPC is the controlling shareholder of the Company and CNPC Finance is a subsidiary of CNPC, and therefore CNPC Finance constitutes a connected person of the Company under Chapter 14A of the Listing Rules. Therefore, the transactions contemplated under the 2023 Derivatives Framework Agreement constitute continuing connected transactions of the Company under the Listing Rules.

Since the highest of the applicable percentage ratios in respect of the 2023 Annual Cap calculated in accordance with the Listing Rules is more than 0.1% but less than 5%, the transactions contemplated under the 2023 Derivatives Framework Agreement are subject to the reporting, announcement and annual review requirements under Chapter 14A of the Listing Rules but are exempted from the circular and independent Shareholders’ approval requirements.
