Major Oil Exporters To China: The Real Winners
China's biggest oil exporters
China's biggest oil exporters are Russia, Saudi Arabia, Malaysia, Iraq, and Brazil, which together supplied about 62% of China's crude imports in 2025 and delivered roughly 358.2 million metric tons of oil. China's import mix is unusually diversified, though, and no single supplier accounted for more than 20% of total imports in 2025.
Why this matters now
The ranking matters because China is the world's largest crude importer, so shifts in its supplier base affect oil prices, tanker routes, sanctions exposure, and geopolitical leverage. In 2025, Russia remained China's largest supplier by volume, while Saudi Arabia held second place and the gap between several major exporters stayed relatively narrow.
China's crude import map is broad, but its center of gravity still sits with Russia, the Gulf states, and a few fast-growing Atlantic suppliers.
Top suppliers in 2025
The latest 2025 data shows that China imported crude from nearly 50 countries, with the largest flows coming from Russia, Saudi Arabia, Malaysia, Iraq, and Brazil. Those five countries accounted for the largest share of China's crude basket, while Angola and Kuwait rounded out the broader top tier.
| Rank | Exporter | 2025 share of China imports | Notes |
|---|---|---|---|
| 1 | Russia | 17.4% | Largest single supplier; more than 100 million tonnes. |
| 2 | Saudi Arabia | 14.0% | Second-largest supplier; over 78 million tonnes. |
| 3 | Malaysia | About 11% | Ranked above Iraq in some 2025 datasets. |
| 4 | Iraq | About 11% | Closely tracks Malaysia in total volume. |
| 5 | Brazil | Top five | Part of China's growing Atlantic Basin supply mix. |
| 6-10 | UAE, Oman, Angola, Kuwait, Canada | Top ten | These countries remain important secondary suppliers. |
How the ranking is changing
The most important change is that China's crude sourcing is becoming more geographically varied even as Russia and Saudi Arabia stay dominant. Reuters noted in March 2026 that neither of China's two largest suppliers contributed more than 20% individually, which underscores how spread out China's import risk has become.
Another major shift is the rise of Malaysia as a major source in recent years, even though it is not a traditional heavyweight exporter on the scale of Russia or Saudi Arabia. The broader supplier list also now includes a wider set of Latin American, African, and North American barrels, reflecting China's push to avoid overdependence on any one route or region.
What the numbers show
According to one 2025 compilation, China bought 578 million tonnes of crude oil from nearly 50 countries, and the top 11 suppliers each shipped more than 10 million tonnes. That same source says those 11 countries together covered about 88% of China's crude imports, which means the market is diversified in absolute terms but still concentrated among a limited group of exporters.
Statista's 2026 chart based on customs data found that the top five suppliers delivered 358.2 million metric tons in 2025, equal to 62% of total imports. That concentration is high enough to matter strategically, yet low enough to give Beijing room to maneuver when prices, sanctions, or shipping disruptions change.
Supplier profiles
- Russia: China's largest supplier in 2025, benefiting from pipeline links, sea-borne cargoes, and discounted barrels.
- Saudi Arabia: Still one of China's most important long-term partners, especially for medium and heavy crude.
- Malaysia: A key transit and blending hub in Asia that has become a surprisingly large source in the rankings.
- Iraq: A stable Gulf supplier with a strong position in China's refining system.
- Brazil: A growing Atlantic supplier that helps diversify China's import geography.
Historical context
The leadership position has changed over time: Saudi Arabia led China's oil supply in several earlier years, while Russia overtook it in 2020 and remained highly competitive afterward. By 2023 and 2024, Russia and Saudi Arabia were still the two core suppliers, but their relative positions shifted as price discounts, freight economics, and refinery demand changed.
In 2024, one trade analysis found the top five exporters were Russia, Malaysia, Saudi Arabia, Iraq, and the United Arab Emirates, together accounting for just over half of China's crude imports. That shows how fast the mix can move from year to year, even if the same core names keep appearing at the top.
Geopolitical implications
China's supplier diversity is a deliberate strategic advantage because it reduces exposure to sanctions, chokepoints, and bilateral pressure from any one country. At the same time, China still depends heavily on several politically sensitive producers, including sanctioned or high-risk exporters in some recent monthly datasets, which means energy security remains tied to geopolitics.
For markets, the key takeaway is that China can shift incremental demand across Russia, the Gulf, Latin America, and Southeast Asia more easily than many importers can. For exporters, that means access to the Chinese market remains enormous, but competition for market share is intense and pricing power is limited.
Key takeaways
- China's biggest oil exporters are Russia, Saudi Arabia, Malaysia, Iraq, and Brazil.
- No single exporter controls more than 20% of China's crude imports.
- The top five suppliers still provide the majority of barrels, so concentration remains meaningful.
- Malaysia, Brazil, and other non-traditional suppliers are gaining importance in China's mix.
- Geopolitics, shipping routes, and refinery economics are driving the latest changes.
Frequently asked questions
Bottom line for readers
China's oil import story is no longer just about the Gulf: it is a multi-region network led by Russia and Saudi Arabia, with Malaysia, Iraq, Brazil, and other suppliers shaping the balance. The result is a market that is large, strategically sensitive, and constantly rebalanced as Beijing manages cost, security, and diplomacy.
What are the most common questions about Major Oil Exporters To China The Real Winners?
Who are China's biggest oil exporters?
China's biggest oil exporters are Russia, Saudi Arabia, Malaysia, Iraq, and Brazil, based on 2025 crude-import data.
Which country is China's largest oil supplier?
Russia was China's largest oil supplier in 2025, with a 17.4% share in one dataset and more than 100 million tonnes shipped.
Does China rely too much on one country for oil?
China is heavily dependent on imports, but not on a single supplier: the biggest country provided less than 20% of total imports in 2025, which makes the system diversified by importer standards.
Why is Malaysia such a large oil exporter to China?
Malaysia has become a major node in regional crude flows, and its role as a trading and blending hub helps explain why it appears near the top of China's supplier rankings.
What changed most in recent years?
The biggest change is the persistence of Russia at the top, the stable importance of Saudi Arabia, and the rising presence of non-traditional suppliers such as Malaysia and Brazil in China's import basket.
