China Petroleum and Chemical Corporation, commonly known as Sinopec Group, is a major Chinese oil and gas company based in Beijing’s Chaoyang District. It operates under the supervision of the State-owned Assets Supervision and Administration Commission (SASAC) of the State Council and has a publicly listed subsidiary traded on both the Hong Kong and Shanghai stock markets. Sinopec stands as the largest oil refining entity worldwide, is a state-owned enterprise, and ranks second globally in revenue, following Walmart.
Domestic
During the mid-1990s, Sinopec was designated for transformation into a state holding company to facilitate partial public offerings of its subsidiaries' assets. In February 2000, Sinopec Limited was formed under the China Petrochemical Corporation Group, subsequently launching initial public offerings in October 2000 on the Hong Kong, New York, and London exchanges, raising $3.5 billion; it later debuted on the Shanghai stock exchange in June 2001.
The company’s foundation traces back to assets transferred from China’s Ministry of Petroleum Industry and Ministry of Chemical Industry. Traditionally more focused on downstream operations compared to PetroChina, Sinopec expanded its upstream activities from the late 1990s onward through asset exchanges with CNPC.
Following China’s accession to the WTO in 2001, domestic oil companies faced increased efficiency demands. Sinopec responded by reducing its workforce by over 200,000 employees prior to its public listing.
In collaboration with BP, Sinopec developed SECCO, an ethylene derivatives facility located within Shanghai Chemical Industry Park. This project began with an initial investment of $2.7 billion and produces over three million tons annually. In 2017, Sinopec acquired BP’s stake in SECCO for $1.68 billion; subsequently, Ineos purchased half of Sinopec’s share as part of a broader agreement.
Sinopec manages the Jiujang Petrochemical Complex, established in the 1970s, which processes eight million tonnes of crude oil each year. Additionally, Zhejiang Oil Products Company—its top-selling refinery—focuses heavily on large-scale production of non-fuel chemicals and attracted Saudi Aramco’s investment with a 10% equity stake acquired in 2023.
In fiscal year 2006, Sinopec recorded an operating margin near 6.8%, limited by government-imposed price controls on downstream products and windfall taxes targeting upstream profits; government subsidies partly mitigated these financial constraints.
Since the mid-2000s, strategic alliances with Saudi Aramco and Exxon have significantly increased refining capacity—for example, tripling output at the Fujian refinery to around 240,000 barrels per day—and fostered fuel marketing ventures overseeing hundreds of service stations.
Sinopec invested over $3 billion to boost ethylene production capacity in Tianjin to roughly 1.3 million tons annually by the late 2010s. It also operates the Gulei Industrial Park in Fujian through a $4 billion joint venture with Taiwanese companies that produces one million tonnes of ethylene each year; Saudi Aramco pledged nearly $10 billion for phase two expansions expected by 2030.
A joint venture with South Korea’s SK Group resulted in an ethylene plant in Wuhan completed in 2012 with an annual capacity of 800,000 tons, supporting China’s efforts to reduce import dependence.
In March 2013, Sinopec purchased overseas oil and gas assets from its parent company for $1.5 billion.
The COVID-19 pandemic led to a ¥23 billion loss in early 2020; nevertheless, revenue grew by 22% in 2021 and net profit increased by 25% during Q1 2022 due to higher diesel production.
In 2021, Sinopec collaborated with NIO Inc. to deploy electric vehicle battery swap stations and jointly develop advanced smart EV technologies and materials.
The company expanded liquefied natural gas (LNG) imports from the United States through major agreements with Venture Global LNG while strengthening partnerships with Saudi Aramco to enhance downstream business operations.
In 2023, Sinopec’s Hainan subsidiary inaugurated a styrene-butadiene copolymer plant with an annual capacity of one million tonnes, establishing it as the world’s largest SBC producer; that same year marked the completion of Asia’s deepest oil well exceeding 9,400 meters in Xinjiang.
Sinopec and BP maintain a long-term joint venture portfolio including more than two thousand gas stations across Zhejiang province as of 2021. At Davos 2024, they signed a strategic cooperation memorandum aiming to establish 5,000 new electric vehicle charging stations by 2025 in alignment with China’s Fourteenth Five-Year Plan environmental objectives.
International
Sinopec, similar to other Chinese state-owned oil enterprises, actively pursues investments in overseas infrastructure projects that often carry significant risks. The company benefits from direct low-interest financing and indirect support through arrangements facilitated by Chinese government-owned banks. Major acquisitions abroad must obtain authorization from China's National Development and Reform Commission and the State Council. Early efforts by Sinopec to secure reserves in Iran (2001) and Kazakhstan (2003) were unsuccessful, prompting a shift toward off-take agreements as a means of entering foreign markets. The global financial crisis of 2008 further redirected Sinopec’s approach towards mergers and acquisitions.
According to the OECD, Sinopec’s international activities are strategic moves aimed at securing China’s oil supply chain. In 2005, Sinopec targeted importing 15 million tons of crude oil for domestic refining, aligning with China’s Go Out policy which promotes overseas resource development and diversification of oil import sources. By 2022, local nationals comprised 74% of Sinopec’s workforce in foreign operations.
Sinopec initiated its collaboration with Iran in 2001, culminating in a $70 billion, three-decade investment agreement for the Yadavaran Field signed in 2004. Despite pressure from U.S. sanctions, production commenced in 2012; however, Sinopec halted Iranian oil purchases in 2019 due to sanction constraints.
In Saudi Arabia, Sinopec deployed its inaugural drilling rig in 2000 and commenced exploration activities by 2004. On the African continent, Unipec secured its initial crude oil purchase contract with Total Gabon in 2002. Although licensing and fee disputes arose with Gabon between 2013 and 2014, negotiations resulted in new lease agreements. In Angola, a $2 billion loan from China’s Export–Import Bank facilitated infrastructure developments favoring Sinopec over competitors such as Shell.
Together with CNPC, Sinopec acquired Ecuadorian petrochemical firm EnCana in 2005 for $1.42 billion, gaining access to substantial crude production and pipeline assets. Despite Ecuador’s oil sector reforms mandating local workforce utilization—which caused many international companies to withdraw—Sinopec continued operations and expanded until environmental activism halted further development in 2019.
As a partner in Sudan’s Petrodar Operating Company Ltd., Sinopec contributed to significant increases in oil output through new pipeline infrastructure. Following South Sudan’s independence—which resulted in most reserves being located there—the pipeline remains crucial for exports but has encountered interruptions due to regional conflicts.
In Russia, Sinopec formed a partnership with Rosneft beginning in 2006, investing in Sakhalin-III projects and acquiring Udmurtneft, thereby accessing over 551 million barrels of reserves with a daily production capacity of 120,000 barrels.
In Ethiopia’s Ogaden region, a 2007 assault by the Ogaden National Liberation Front on a Sinopec drilling site caused casualties but did not deter the company’s commitment to operations there.
Sinopec acquired Syria-based Tanganyika Oil for $2 billion in 2008, obtaining fields with reserves exceeding one billion barrels; nonetheless, the outbreak of the Syrian civil war forced cessation of activities by 2012.
In Australia, Sinopec gained majority control of AED Oil in 2008 through a $594 million acquisition, taking over underperforming Puffin oil fields.
The purchase of Addax Petroleum Corp for $7.24 billion in 2009 represented the largest foreign acquisition by a Chinese firm at that time. Addax's assets were concentrated in West Africa and Kurdistan; however, controversies including a Swiss bribery investigation led to closure of its Geneva office by 2017. Tax disputes with Nigerian authorities were resolved by 2015.
Sinopec acquired ConocoPhillips' 9% stake in Canadian Syncrude for $4.65 billion in 2010 and purchased Daylight Energy for C$2.2 billion in 2011 (rebranded as Sinopec Daylight Energy Ltd). These moves aimed to develop expertise in oil sands extraction to enhance domestic production capabilities.
In Brazil, Sinopec invested $7.1 billion into Repsol Brazil (2010) and $5.2 billion for a stake in Galp Energia's Brazilian division (2011), securing rights to major offshore reserves along with deepwater drilling expertise.
Starting from 2011, Sinopec partnered with Chevron Corporation to acquire an 18% interest ($680 million) in Indonesia's Kutai Basin deepwater project which holds substantial crude and gas reserves—supporting China's strategy to increase natural gas consumption.
Unipec entered Ghana via a $3 billion six-year loan linked to oil supply contracts and infrastructure projects carried out by Chinese firms; however, delays in funding slowed project implementation.
In Cameroon, Sinopec Addax purchased Shell’s majority stake in Pecten offshore exploration assets during 2011.
Beginning in 2015, Sinopec expanded joint ventures with BP focusing on bunker fuel supply projects that delivered fuel across Singapore, China, and Europe by 2020.
Addax invested $1.5 billion into North Sea drilling operations in 2012; after settling disputes involving Repsol for $2.1 billion by 2023, the investment was rebranded accordingly.
In Myanmar, Sinopec divested an oil block stake to Taiwan's CPC Corp (2013) while acquiring a $3.1 billion interest in Apache Corporation's Egyptian assets the same year.
In Angola, Sinopec purchased Marathon Oil’s offshore fields for $1.52 billion (2013) and retains minority stakes through joint ventures such as Sonangol Sinopec International. Additionally, it co-owns POLY-GCL Petroleum which is developing a $4 billion Ethiopian LNG project connected to Djibouti export facilities—reflecting China's commitment to importing African LNG supplies.
In November 2021, Sinopec signed China’s largest long-term LNG contract—a twenty-year agreement with U.S.-based Venture Global LNG—and offered up to 45 LNG cargoes for sale during 2022 to capitalize on elevated Asian spot prices.
Despite international sanctions following Russia's invasion of Ukraine (2022), Sinopec continued operations in Russia via subsidiaries like Unipec acting as intermediaries for restricted Russian oil; however, reports indicate that purchases were suspended starting March 2025 due to sanction risks.
Sinopec became the first Asian participant in QatarEnergy's North Field East LNG expansion project (2023), acquiring a 5% equity stake valued at nearly $29 billion along with a record-setting 27-year purchase agreement.
By mid-2023, Sinopec established Overseas Investment Holding as an entity focused on refinery investments abroad—including stakes at Saudi Arabia's Yasref refinery (400,000 barrels daily) and Russia's $10 billion Amur Gas Chemical Complex—and procured over thirty LNG cargoes via tender ahead of winter demand peaks.
In October 2023, an equity partnership was finalized with KazMunayGas JSC for a $7.7 billion polyethylene plant project in Kazakhstan scheduled to commence construction later that year.
Furthermore, Sinopec secured approval for a $4.5 billion refinery investment at Sri Lanka's Hambantota International Port (2023), broadening its global refining portfolio.
Governance
Sinopec is classified as a "core" central state-owned enterprise managed by SASAC. The chairman, similar to leaders of other Chinese National Oil Companies, holds a vice ministerial rank—a political role appointed by the Ministry of Personnel, typically granted to senior Communist Party officials as recognition for their contributions to the industry. This elevated leadership status enables Sinopec to exert significant influence over governmental policies related to financing, international agreements, and pricing strategies. Although state-owned, Sinopec did not distribute dividends to the government until 2008 and maintains representation within the Central Committee of the Chinese Communist Party. Certain investments made by Sinopec, particularly in countries such as Iran and Sudan, were viewed as politically sensitive, leading to regulatory reforms that impose personal liability on executives for financial setbacks.
The governance structure consists of a Board of Directors whose members are proposed by a nominating committee that includes the chairman. The company highlights its commitment to diversity, reporting that women constitute 10% of board members and 31% of its workforce. Nevertheless, its audits lack the independent supervision commonly found in publicly listed Chinese companies.
Chen Tonghai, who previously chaired the board, was convicted of corruption and sentenced to death in 2009 after his removal in 2007. He was replaced by Su Shulin, formerly the head of CNPC. In response to this scandal, Sinopec undertook efforts to reform its corporate culture and dissociate itself from the period under Chen's leadership.
Environmental and safety record
In 2004, Sinopec’s oil exploration activities within the 1,550 km² area of Loango National Park in Gabon attracted criticism due to environmentally harmful practices. Conservation experts including Christophe Boesch from the Wildlife Conservation Society condemned the use of explosives and heavy equipment, which posed risks of displacing gorillas into unprotected zones. While Gabonese legislation permits oil extraction within national parks under conditions requiring environmental restoration, Sinopec was urged to implement less disruptive methods such as horizontal drilling. In 2006, the Gabonese national parks authority suspended Sinopec’s operations. After revising its environmental impact assessment in cooperation with both local and international conservation organizations in 2007, Sinopec resumed production employing enhanced environmental safeguards.
On 21 December 2006, a gas leak occurred during drilling operations conducted by Sinopec’s Southern Prospecting and Development Branch in Quingxi, necessitating the evacuation of 12,380 residents. The leak persisted for two weeks and required three attempts before being successfully contained.
In 2007, China’s State Environmental Protection Administration (SEPA) mandated a suspension of activities at an oil field operated by Sinopec’s Zhongyuan Oilfields Petrochemical Company due to persistent river pollution and inadequate wastewater treatment compliance, resulting in imposed fines. Subsequently, in February 2008, the Guangdong Provincial Environment Bureau issued a red alert to 19 companies including Sinopec Guangzhou for excessive emissions and significant pollution violations.
An explosion on an oil pipeline on 22 November 2013 in Qingdao, Shandong province, led to at least 62 fatalities and wounded 136 individuals after leaked oil ignited.
Sinopec’s total greenhouse gas emissions amounted to 172.56 million tonnes of CO2 equivalent in 2021. By 2023, this figure slightly decreased to 169 million tonnes CO2 equivalent, preserving its status as the second-largest emitter among global oil corporations.
Renewable energy
By 2021, Sinopec had become the foremost provider of geothermal energy within China, with plans to broaden its role in promoting "smog-free urban areas."
The company has implemented a large-scale carbon capture, utilization, and storage (CCUS) initiative in China, featuring the Sinopec Qilu carbon capture project alongside CO2 capture and storage efforts at the Shengli Oil Field, both operational since January 2022. Collaborations with industry leaders such as Baosteel, Shell, and BASF support Sinopec’s ongoing CCUS research and innovation.
Sinopec led China’s production of grey hydrogen—hydrogen generated through petrochemical processes without carbon capture—as of 2021. In 2023, it inaugurated its inaugural solar-powered green hydrogen plant in Xinjiang, aiming for an annual output of 20,000 tonnes to supply its Tahe refinery. The Demonstration Project for Hydrogen Transmission Pipeline from Ulanqab to the Beijing-Tianjin-Hebei area seeks to integrate grey, blue, and green hydrogen initiatives via a pipeline system stretching from Inner Mongolia to Beijing. The company highlights transportation infrastructure as a significant challenge to broader hydrogen adoption. In line with this, a 20,000-tonne-per-year green hydrogen wind farm was established near Ordos City in 2023.
Research Institutions
Sinopec manages multiple research centers, notably the Research Institute for Petroleum Processing (RIPP), founded in 1956 and active prior to the company’s public listing. RIPP continues to generate patents that bolster Sinopec’s technological and operational strengths.
