Ladies and gentlemen, good afternoon. I am PetroChina’s CFO and Board Secretary, Chai Shouping. I would like to welcome you to our 2021 Annual Results Announcement. First, allow me to introduce the board members and top management present today. Chairman, Mr. Dai Houliang; Executive Director and Senior Vice President, Ren Lixin; Vice President, Tian Jinghui; Vice President and Chief Engineer, Mr. Yang Jigang; Chief HSE Supervisor, Mr. Zhang Minglu. The presentation today includes four parts: first, review and analysis of 2021 financial performance; next, overview of operational performance; then remarks from the Chairman followed by a Q&A session. Now, I will walk you through our financial performance of 2021. Last year, we are driving oil prices, steady recovery of Chinese economy and booming demand for oil and gas that followed through on high-quality development requirements and make coordinated progress on business development going at low-carbon transition, reform and innovation, quality and efficiency, HSE and COVID response. Oil and gas industry maintained stable operation. Operation performance was 7-year high. Realized oil price averaged $55.56 per barrel, up 62.6% year-on-year or up 7.6% versus 2019, with a 2-year average growth of 3.7%; revenue, CNY2.6 trillion, up 35.2% year-on-year, marking a new record high; operating profit, CNY161.15 billion, up 112.2%; net profit attributable to the parent CNY92.17 billion, up 385% year-on-year, up 111.8% versus 2019 with a 2-year average growth of 42%; earnings per share, CNY0.50. We remain committed to prudent, targeted and profitable investments based on oil price changes, operational performance and cash flow. We just did an optimized investment finance structure further enhance investment management to improve returns. 2021 CapEx totaled CNY251.8 billion, up 1.9% year-on-year. The overall scale is reasonable and well controlled. As the foundation of our development, E&P business remains a CapEx priority, which totaled CNY178.26 billion, accounting for over 70%. We steadily improved into growing a low carbon transition, CapEx on new energies, new materials and new business totaled CNY3 billion. In 2022, we plan to invest another CNY10 billion. Last year, we continue to improve quality and efficiency in health control and achieve notable results. Growth of major cost was far smaller than that of income. Leasing cost in China, $13.06 per barrel, around flat year-on-year adjusted for RMB appreciation. Cash per testing cost CNY166.65 per ton despite higher cost of deals and power. The cost was well controlled, up only 1.7% year-on-year. We will work on fund management, financing costs CNY16.22 billion, down 30.7% year-on-year. We made rationale investment decisions enhanced asset management for the optimized asset liability structure, financial profile remains sound.

Debt-to-asset ratio, 33.7%, down 1.4 percentage points; debt-to-capital ratio, 19.5%, down 1.8 percentage points versus end of last year, the lowest since 2011. We value cash flow management and saw large rise in free cash flow. Operating cash flow, CNY341.47 billion, up CNY22.89 billion year-on-year or 7.2%. Free cash flow, CNY79.85 billion, up 13.8% mainly due to increased operating cash flow and stronger CapEx discipline. We will further tighten fund management to ensure appropriate and ample cash flow. Operating profit of E&P CNY58.45 billion, up CNY45.36 billion plus changes of oil and gas products at CNY156.27 billion. Changes in sales cut CNY8.46 billion, more sales of natural gas cut CNY7.43 billion, lower sales of crude cut CNY15.89 billion, mainly due to sales declines overseas. OpEx up by CNY102.45 billion, including purchased services and other costs by CNY42 billion, mainly due to higher cost of crude imports. CD&A grew by CNY24.48 billion. Tax, except income tax, went up by CNY13.157 billion, including CNY4.48 billion from the windfall tax. Operating profit of refining chemicals, CNY49.74 billion, up CNY51.57 billion. Operating profit from refining, CNY37.73 billion, up CNY50.53 billion. Higher refining margin adds to profit by CNY53.45 billion, while crude run at CNY1.54 billion, higher OpEx caused a profit by CNY4.46 billion. For chemicals business, operating profit was CNY12.01 billion, up CNY1.04 billion year-on-year. Price changes added profit by CNY53.64 billion, mainly due to upward chemicals market in China and PetroChina optimized product mix and boosted the development, production and marketing of high-end and high value-added chemicals and raw materials. Changes in sales at CNY2.09 billion, higher OpEx had profit by CNY54.69 billion, mainly due to increased purchase service and other costs.

Thank you, Chairman Dai for PetroChina’s annual results announcement part. Now, we will have our Q&A session with consecutive integrating available. And now the floor is open for questions.

The first question is Hong Xiang from 21st Century Business Herald.

Congratulations on the stellar results of PetroChina in the year 2021. I’ve got two questions. First question is concerning the press conference out by the Ministry of Foreign Affairs and some journalists asked about the three oil companies in China potential purchasing of Russian assets, and I’m wondering about what is the impact of the Russian and Ukraine situation on the international oil and gas market and also on PetroChina’s International Corporation. The second question is concerning your green and low-carbon transition. In the year 2021 through our arduous efforts to stabilize crude production and increase natural gas production, PetroChina has managed to cut CO2 emission by 260 million tons, which is remarkable. Could you please give us more color on the new progress in your green and low carbon transition strategies?

I invite our Chairman, Mr. Dai Houliang, to take these two questions.

Hi. Thank you, my friend from the Twenty First Business Herald for your questions. And these are two quite big questions, and I can only give you very brief answers. The Russia and the Ukraine situation has profound impact globally and especially on the international energy market, impacted by multiple factors. The international crude price went up by 50% to 70%. And currently, it is still fluctuating at a very high level. Global energy, especially natural gas and crude oil, is now facing risks in supply. PetroChina has been following closely the changes in the energy market and as a public company will bear ESG in mind, actively fulfill our social and environmental responsibilities. We have taken several measures to our utmost to ensure the supply in the natural gas and crude oil market. And currently speaking, the supply is right on track, but the cost inflation is also significant. For many intake, the following three aspects of measures to guarantee the supply: first, we are working on the international exploration and production to try to increase the effective supply of natural gas and crude oil in the Chinese market, including increasing our CapEx, optimizing operation plans, increase in reserve and production. Second, we are intensifying trade activities. For many years, PetroChina has maintained sound partnership with many natural gas and crude oil producers, and there’s multiple long-term contracts being executed right now. And currently speaking, our business is normal. And third, we are focusing more on long-term and green and low carbon transition, we intensified to our investment in new energy sector including wind power, solar power, geothermal, hydrogen, etcetera. And our new energy investment in this year is expected to grow by more than 2x, and we wish to increase the effective supply of our total energies in order to ensure to meet the energy demand for our social and economic development. And I’ll take your second question. The green and low carbon is one of our five development strategies, green and low carbon transition and development is a requirement for PetroChina to adapt to the growth energy transition, but also an intrinsic requirement for us to achieve high-quality and sustainable development. Hydro China has actively responded to the government’s requirement to achieve carbon neutral and carbon peak targets and we aim to achieve peak carbon by around 2025 and near zero emissions by around 2050, but working to intensify and deepen the implementation of our green and low-carbon development strategies. We have set the time line and road map for us to achieve peak carbon, and we have launched a three-step scheme of clean alternatives, strategic replacement and green development. We’re working on the planning of green industries in order to forge a low-carbon energy ecosphere with integrated development of fossil fuels and new energies. We’re also working on building a new situation of many different energies reinforcing each other and build PetroChina into an integrated energy company that provides oil, gas, heat, power and hydrogen. In the past year, we are implementing our 14th 5-year plan and working on our initiative to stabilize oil production and increase natural gas production. Our domestic natural gas output took about 51.6% of our total oil and gas output in China. And for the whole year, we sold natural gas 194.6 BCM in China, which is equivalent to replacing 259 million tons of standard coal for a reduction of 260 million tons of CO2. We have been working hard on the integrated development of geothermal, wind power, solar power and gas-fired power and we are working on the full value chain development of hydrogen, including its production, transportation, storage and utilization. And in this past Winter Olympic Games, PetroChina provided hydrogen for vehicles with very high purity that’s hydrogen vehicles and also green hydrogen for the main torch of the Winter Olympic Games, which has our own intellectual property rights. Efforts have also been made in the planning of CCS and CCUS industry and the new energies industry. We have carried out a series of new energy projects, including 39 projects put into production. And we added the development and utilization capacity of new energies, which is equivalent to 3.5 million tons of standard coal per year, we realized a fast start of the new energy business. PetroChina is aware that in our efforts to achieve peak carbon and carbon neutral targets, also energy, especially natural gas and crude oil will remain to be very important. So we have intensified our efforts in domestic E&P to ensure supply, and we will fully harness our advantage in natural gas resources to focus on the natural gas business development. And we hope we can see fairly rapid growth of natural gas production in China, and our target is to increase our natural gas percentage in our total output to 55% by 2025. In the development of clean energy PetroChina will fully utilize our resources of wind, solar and geothermal in the areas where we have the mineral rights and the surrounding areas. We focus on new energy business and our target is to increase the development and utilization volume of new energies equivalent to 23.5 million tons of standard coal by 2025 or 7% of our total production capacity. Few energy, oil and gas are expected to take one-third, respectively, in our portfolio by 2035, and new energy production capacity is estimated to increase to half our total portfolio by 2050. Thank you.

The next question is from Credit Suisse. Please go ahead.

Congratulations on your last year’s excellent performance. I’ve got two questions. First one is concerning your input in natural gas losses, which were better than expectation in 2021 and especially in Q4, the loss even went down quarter-on-quarter. So my question is, how do you look at the import gas losses in the year 2022, especially against the high oil price environment. What measures will the company take to pass through your import costs. And second question is about the company’s dividend. And in last year, your dividend payout ratio has been returned to the basic 45% sales ratio and we will see improving cash flow in the year 2022. So I’m wondering about the outlook on the dividend policy in the year ‘22 and beyond.

Our CFO, Ren Lixin, will take your question.

First on imported the natural gas loss. Last year, PetroChina sold imported gas of about ADBCM with a loss of RMB7.21 billion, which is a reduction of RMB6.59 billion. For the reduction of import gas losses we may have four reasons. The first is our efforts development of high-end markets, including the direct sales and the development of end user market. And second, we have pressed ahead with the natural gas prices to be more market-oriented. We set up a negotiation system for the natural gas purchase and sales contracts and enhanced the trading of online resources, especially extra contract resources and intensified the free choice of both sellers and buyers. And the third reason is the Chinese government has issued new tax refund policies for imported natural gas. And the tax refund is increased, especially for those long-term contracts signed before the year 2014, which have contributed an additional RMB5 billion. And the last reason is the reduction of import costs because the import gas prices is linked with crude prices and have a 9-month lag. The imported gas cost is impacted by multiple factors, including the international crude prices foreign exchange rates and the market situation. And in the year 2022, we will arrange our import scale based on the market situation and our resource balance. Thank you. And on the dividend policy, since the company got listed, we have maintained very stable payout ratio of 45%. In recent years, we have witnessed to very low crude oil prices and in those years the company has issued special dividends on the back of the 45% payout ratio. Last year, PetroChina has seen stellar results in our operations, and yesterday we hold the Board meeting and the Board are suggest the general shareholder meeting to decide on a 45% payout ratio for last year. Therefore, for the annual dividend, the amount is RMB0.22 per share with a total number of RMB41.5 billion, in total dividend. And the final dividend was RMB0.96. As you just mentioned, in 2021, our cash flow is quite redundant, and free cash flow was RMB79.5 billion. And as decided on our Board meeting yesterday, our cash flow in addition to dividend will be used in the following three areas. The first is the cash flow will go to green and low carbon transition for high-quality development of the company. And second, it will go to the domestic on gas exploration and development, especially the development of natural gas to ensure stable supply in the market. And third, the money will be – will go to managing down our leverage and to maintain a prudent financial position of PetroChina. Thank you.

The next question is . Please go ahead.

My first question is about your new energies and new materials business. And last year, we have seen quite great achievements in these three regards, and we have seen your establishment of two research institutions and one – and some geothermal projects were put into production. And also, you have made new efforts in the new energies development. I am wondering about your new plans for new energies and new materials in the years ahead. And second question is about the company’s earnings. Last year, your earnings has improved quite a lot. And some say it’s because of the increasing of the crude oil prices, and we can also tell from your annual report that the crude oil price went up by 7.9%, but your earnings improved by 101%. So, I am wondering about the real reasons behind your performance improvement.

I invite Mr. Yang Jigang, Vice President and Chief Engineer of the company, to take your questions.

I will take your question for the new energies and new materials, which has attracted a lot of attention. And these two areas did require a lot of investment as well. PetroChina is an integrated energy company having both the upstream, midstream and downstream of the oil and gas value chain. And for the chemicals materials, we have our advantages in terms of knowledge, technology experience and our market share. And we have maintained – we have made quite a lot of efforts in developing new energies and new materials. The Chairman of PetroChina now chairs our leading group on the development of new energies and new materials. We have prepared a strategic development plan for the new energy business development and also organized the business management systems. As you mentioned, we have set up a Shenzhen New Energy Research Institute and a Shanghai New Material Research Institute. And in our E&P company and its oil field companies, they all set up a new energy business division and the oil refining chemicals company and our integrated refining and chemical companies in different localities in China, they set up a new materials business division. Our Chairman has made it quite clear about our energy transition initiatives. And it is frankly – frankly speaking PetroChina focused quite a lot on the new power generation of hydrogen and new energies. And we are working on the integrated development of solar power, wind power and gas-fired power plants and storages. And we are working on the western part of China to participate in the government-led initiative of developing wind, solar, power basis, which is surrounding the treatment of . In terms of development of new materials by focusing on synthetic rubber and performance, synthetic resins and also the new materials used in electronic separation, Medicare and the storage of wind and solar power, in transportation, in aviation and airspace sectors. In the year ahead we will recommence the plants in new energies and new businesses and also the annual plans in the 14th 5-year plan period, we will try to achieve sizable development of multiple new energies, including geothermal, wind power, solar power and gas fired power. And we are working on new energies and new materials on CCS and the new energy supporting and service sectors and we are trying to develop series of new energy development and new materials development technologies. The focus is to press ahead with the development of the six spaces and try to achieve the organizational management, technological support and the industrial systems for new energy, new material and new business. We expect the development and utilization volume of new energies will be equivalent to 23.5 million tons of standard coal by the year 2025, and the capacity will reach 7% of the company’s total and we also expect the percentage of new materials in our total chemicals materials to be above 15% to further enhance our ability to meet the market demand. Thank you.

Thank you, Mr. Yang, and I will take the second question. I am CFO, Chai Shouping. In the year 2022, PetroChina’s performance has improved very significantly. Our net income attributable to the parent reached RMB92.17 billion, an increase of 385%. And as stated by our Chairman someday that due to our efforts made by all the employees and also by grasping the good opportunities. First, we have witnessed a very significant increase of crude prices and China’s economy recovered steadily and the demand recovered as well. And second, we have been working on a special program to enhance the quality and efficiency of the company’s development. In terms of our domestic crude oil and marketable natural gas output, the numbers went up by 1.3% and 5.7% respectively. And our domestic refined oil products sales volume, the chemicals commodity volume and domestic natural gas sales volume went up by 6.2%, 6.7% and 12.7% respectively. And third, efforts have been made to implement our low-cost development strategy, we have continuously strengthened cost and fee control and management and the growth of our revenue far outweighs the growth of our costs and fees, especially our weighted average interest rate decreased by 30.7%. Efforts made in quality and efficiency improvement has contributed an earning of RMB10.5 billion, before business segments of the company have all witnessed profits. Thank you.

Time is running short, one final question.

The last question is Securities. Please go ahead.

Since the year 2018, the company has been working actively to respond to the government’s call to ensure China’s energy security and the company has made quite considerable and stable CapEx in the upstream sector over the years with a lot of breakthroughs and achievements made in this sector. And in the year 2021, I am wondering about what significant discoveries have you made in your exploration activities in China. And as you know, reserve is the most important core competitiveness of an oil company and last year, PetroChina’s reserve replacement ratio amounted to 2.21, which is really seen in international oil companies, so how do you manage to achieve that. and for the second question is about the oil prices, and in this year 2022, the crude oil supply and demand is quite tight, which has brought up the crude oil prices. So, based on the current pricing mechanism, I am wondering about the impact on your refining chemicals and marketing businesses when crude oil prices stands at $80 to $130 and above $130?

I invite Mr. Ren Lixin, Senior Vice President, to take your first question.

In the last year, our domestic E&P business has sticked to innovation-driven approach. We have enhanced our efforts in oil and gas exploration and development in China and especially on effective exploration and reserve, and production ramp-up. Last year, we have made five significant, strategic breakthroughs in Junggar basin, Erdos basin, Sichuan basin and Tianan basin. We have discovered multiple reserve zones with sizable reserves and our reserve replacement ratio went up significantly. According to the appraisal of E&M, the independent third-party reserve appraisal agency, in the past year, PetroChina’s domestic oil and gas reserve replacement ratio by SEC standards was 147%, around which crude oil 221%, which is a record high since the company got listed. Thank you. Our Chairman would like to add several information.

I want to add that E&P efforts is a long-term process. Since the year 2018, PetroChina has echoed the government’s call to intensify our domestic E&P efforts and we have been working on that continuously. And in the year 2020, we see very low crude prices, but we have maintained our investment in risk-taking exploration. So, many years of efforts will bring benefits in the end. So, these many years of CapEx allocated in our upstream sector has brought up very good output for us to see last year and with improving reserve replacement ratio and more solid foundation in our regional space. Thank you.

I am CFO, Chai Shouping. I am taking the second question. The national – the NDRC issued a regulation on crude prices, which prescribes that when the international crude price rise above $80 per barrel, the gross refining margin will start to reduce and until – based on zero profit of processing profit to calculate the crude – the refined oil product prices. When the international crude price goes up above $130 per barrel, and of course, could price above $130 per barrel may not be sustainable. And if that happens, the diesel and gasoline prices in principle will not increase, we will only see very modest increase. From the perspective of PetroChina, we will strictly comply with the national micro regulation policies and on the other hand, also advocating with government authorities to set prices based on market terms in order to ensure stable supply of oil and gas. Thank you.

Ladies and gentlemen, that’s the end of today’s result announcement. Thank you for your participation.
