Suppliers shipping oil to China: what you need to know
China's crude oil demand is met by a highly diversified global supplier base, anchored by Russia, Saudi Arabia, Mexico, Brazil, Angola, and other producers across the Middle East, Africa, and the Americas. In 2025, these six countries alone accounted for roughly 62% of China's recorded crude imports, with Russia and Saudi Arabia together representing more than one third of total volume.
Top crude oil exporters to China
China's accession to the world's largest oil importer status has reshaped global trade flows, and today its top suppliers are a mix of traditional Gulf exporters and newer players benefiting from price discounts and flexible swaps. By 2025, the five largest formal suppliers-Russia, Saudi Arabia, Mexico, Brazil, and Angola-delivered 358.2 million metric tons of crude, equaling about 62% of China's total imports.
- Russia - Leading supplier in 2025, with roughly 17.4% of China's crude imports by volume, up from 14% in 2023.
- Saudi Arabia - Second-largest official supplier, providing about 14% of China's crude in 2025.
- Mexico - Emerged as a core supplier, contributing roughly 9-10% of total imports in 2025.
- Brazil - Exports to China grew by nearly 28% year-on-year, reaching over 800,000 barrels per day by mid-2025.
- Angola - Long-standing African partner, supplying about 4-5% of China's crude on an annualized basis.
Behind them, United Arab Emirates, Oman, Kuwait, and Canada round out the top-10 list, with each typically contributing 3-5% of China's annual crude volumes.
Share and volume by key supplier (2025 illustrative)
Even though precise custom figures vary by source, the relative ranking of major suppliers is well established. The table below synthesizes recent trade data into a representative snapshot for 2025, suitable for commercial reference and pipeline-planning models.
| Supplier | Approx. share of China's crude imports (2025) | Illustrative volume (million b/d) |
|---|---|---|
| Russia | ~17.4% | 1.9-2.1 |
| Saudi Arabia | ~14.0% | 1.5-1.7 |
| Mexico | ~10.0% | 1.1-1.3 |
| Brazil | ~8.0% | 0.8-0.9 |
| Angola | ~4.5% | 0.5-0.6 |
| UAE | ~4.0% | 0.4-0.5 |
| Oman | ~3.5% | 0.4 |
This distribution reflects Beijing's strategy of "multi-sourcing" via a mix of long-term contracts, spot purchases, and complex swap arrangements with state oil companies and private traders.
Behind the scenes: Sanctioned and indirect flows
Official customs data capture only part of the picture; analysts tracking tanker movements estimate that a significant share of China's crude comes indirectly via third-country intermediaries and "shadow" flows. For example, one major trade-flow tracker calculated that in 2025, China imported roughly 2.6 million barrels per day of sanctioned or off-book crude, amounting to about 22% of total recorded imports.
Within that shadow segment, Iran and Venezuela are widely believed to be the largest contributors, often routed through intermediaries such as Malaysia or other Asian trading hubs. At the height of tension in mid-2024, Iran's shipments to China via these routes briefly exceeded 1.9 million barrels per day, temporarily surpassing Saudi Arabia's recorded volumes.
- Iranian crude - Market-flow estimates suggest Iran supplied 1.3-1.4 million barrels per day to China in 2025, usually under opaque ownership or origin labels.
- Venezuelan crude - Independent data show Venezuela exporting about 350-570 thousand barrels per day to China, primarily via third-party blending and re-flagging.
- Blended streams - A growing share of "Malaysian" and "Singaporean" crude entering China is suspected to contain re-labelled Iranian or Venezuelan barrels, complicating sanctions enforcement.
These indirect channels allow Chinese refiners to tap heavily discounted crude while maintaining a degree of formal distance from sanctioned producers, and they have become a key feature of China's energy security calculus.
Geopolitical and commercial drivers
China's supplier mix has shifted noticeably since 2020, driven by sanctions, war-risk premia, and Beijing's push for "energy security" with non-Western partners. Before Russia's full-scale invasion of Ukraine, Saudi Arabia and other Gulf states dominated China's crude basket; in 2023, Persia-Gulf supplies plus Russia already accounted for nearly three-quarters of imported volumes.
By 2025, Russia had overtaken Saudi Arabia as the top supplier in some months, trading on steep discounts while Indian and Chinese buyers bid aggressively for discounted Urals-type and ESPO grades. At the same time, China's appetite for heavier sour crude from Iran and light, high-yield Brazilian and West African blends has made its refining system uniquely flexible compared to other major importers.
A senior analyst at an international trade-flow firm recently noted that, "China's crude sourcing is less about geopolitics per se and more about price-volume optimization, with the government comfortable using multiple channels to secure the cheapest barrels." That "price-volume optimization" has led to long-term contracts with Russian and Saudi producers, short-term swaps with African and Latin American exporters, and opportunistic spot purchases during global price dips.
These arrangements are typically governed by flexible pricing formulas linked to Platts Dated Brent, MARS, or Dubai-Oman benchmarks, giving Chinese buyers exposure to both Western and Asian price signals. In parallel, state-owned trading platforms such as China's Oil & Gas Pipeline Network Corp (PipeChina) and the Shanghai International Energy Exchange are increasingly used to hedge and price barrels, reinforcing China's role as a central node in the global oil-trading infrastructure.
This "blended-hub" model allows Chinese refiners to obtain barrels at spreads well below official benchmarks while still complying with customs and regulatory constraints. As a result, private trading desks and regional hubs have become de facto intermediaries in China's energy-security architecture, even as official statistics emphasize only the top-listed suppliers.
At the same time, regulatory scrutiny and potential new sanctions on Russian and Iranian flows could push China farther into "gray-trade" channels via blending hubs, legal swaps, and complex ownership structures. For global traders and investing firms, understanding this evolving web of formal suppliers and indirect channels is essential to forecasting China's price behavior and logistics demand over the next five years.
Everything you need to know about Oil Exporters That Move Product To China Find Partners Now
Who are the largest oil suppliers to China in 2025?
The largest official suppliers of crude oil to China in 2025 are Russia, Saudi Arabia, Mexico, Brazil, and Angola, with these five countries together accounting for about 62% of recorded imports. Additional significant contributors include the United Arab Emirates, Oman, Kuwait, and Canada, each typically supplying 3-5% of China's annual crude volumes.
Does China still buy oil from Russia and Iran?
Yes, China continues to receive substantial volumes of crude from both Russia and Iran, but the channels differ sharply. Direct Russian exports to China have surged, with Russia supplying roughly 1.9-2.1 million barrels per day in 2025 under official trade data. Iranian crude, by contrast, is largely channeled through third-country intermediaries and re-branded cargoes, so it does not appear under "Iran" in Chinese customs reports, even though market-flow estimates put Iranian-origin barrels at around 1.3-1.4 million barrels per day flowing to Chinese refineries in 2025.
What share of China's oil imports comes from the Middle East?
Collectively, Middle Eastern suppliers account for roughly 40-50% of China's documented crude imports, depending on the year and data source. In 2023, Gulf Cooperation Council (GCC) countries plus Iraq and Iran supplied more than half of China's imports, with GCC members alone delivering about 36% of total volumes. By 2025, that share stabilized in the mid-forties range as China diversified further into Russia, Latin America, and Africa.
How diversified is China's crude supply base?
China's crude supply base is notably diversified, with no single country consistently exceeding 20% of total imports in recent years. In 2025, Russia's share peaked at about 17.4%, while Saudi Arabia hovered around 14%, and the remaining 10-15 largest suppliers each contributed 3-10% of annual volumes. This structure allows Chinese refiners to pivot quickly between grades and pricing benchmarks, making China one of the most agile buyers in the global oil market ecosystem.
How do Chinese refiners contract with foreign oil companies?
Chinese refiners work with foreign oil companies through a layered mix of long-term contracts, term agreements, and spot trades, often coordinated by national trading houses and state-owned marketing arms. Major Chinese groups such as Sinopec, PetroChina, and CNOOC sign multi-year crude supply deals with producers like Rosneft, Saudi Aramco, and Brazil's Petrobras, while also running dedicated trading desks that compete aggressively for discounted cargoes in the Atlantic and Indian Ocean basins.
What role do private traders and blending hubs play?
Private traders and offshore blending hubs are critical enablers of China's multi-sourced oil strategy, especially for sanctioned or discounted barrels. Companies based in Singapore, Malaysia, and the UAE routinely purchase crude from Iran, Venezuela, and deep-discount Russian grades, then re-blending or re-labeling it before shipping to China under generic trade labels.
How might China's oil-supplier mix change in the next five years?
Analysts expect China's supplier mix to remain broad but with deeper structural dependence on Russia, Brazil, and select Gulf partners, while African and Latin American volumes fluctuate around 15-20% of total imports. The completion of additional Russian pipeline and rail infrastructure, coupled with expanding Brazilian offshore output and Gulf investments in light-sour crude projects, is likely to lock in long-term contracts that favor China's refining configuration.
