China's Oil Suppliers: The Power Shift People Missed
Top Oil Exporters to China
China's crude basket has become increasingly concentrated in recent years, with roughly two dozen countries supplying the lion's share of its imports. Among the leading crude oil suppliers, Russia surged past Saudi Arabia in 2023 and has since maintained the top position, delivering an estimated 17-18 percent of China's total crude volume in 2025.
- Russia - Accounts for roughly 17-18 percent of China's crude imports in 2025, up from about 16 percent in 2023.
- Saudi Arabia - Holds the second-largest share, supplying about 14 percent of China's crude in 2025.
- Malaysia - Emerged as a key Asian hub, contributing around 10-11 percent of China's imports by 2024-2025.
- Iraq - Provides roughly 7-8 percent of China's crude, with strong pipeline and terminal infrastructure in place.
- Brazil - Has doubled its presence since 2020, now accounting for about 4-5 percent of China's imports.
Shifts in China's Oil Geography
For decades, China's oil import pattern was dominated by Middle Eastern producers, with Saudi Arabia and Iraq as anchors. By 2025, however, Russia's share exceeds that of any single Gulf producer, reflecting a strategic pivot toward long-term, discounted Russian crude and expanded pipeline and rail capacity.
The rise of Middle Eastern Gulf states as a group-Saudi Arabia, Iraq, the UAE, Kuwait, and Oman-still matters: together they supply roughly 35-40 percent of China's crude, though Russia's share is now similarly large on its own. At the same time, non-OPEC suppliers such as Brazil, the United States, and Canada have gained ground, especially as Chinese refiners seek diverse grades and flexible pricing.
Sample supplier table (2025, illustrative)
| Supplier | Share of China's crude imports (%) | Approx. daily volume (mn bpd) |
|---|---|---|
| Russia | 17.4 | 2.1 |
| Saudi Arabia | 14.0 | 1.7 |
| Malaysia | 10.5 | 1.3 |
| Iraq | 7.6 | 0.9 |
| Brazil | 4.8 | 0.6 |
Data in this table are stylized to match recent trade studies and customs-backed estimates, but they should be treated as a conceptual snapshot rather than a statutory dataset.
Key non-Gulf suppliers
Beyond the Middle East, several non-Gulf exporters have become material to China's energy security. Brazil, for example, increased its crude deliveries to China by roughly 28 percent year-on-year in 2024-2025, reaching about 200,000-210,000 barrels per day. The United States, once a minor supplier, has also grown from under 1 percent to around 3-4 percent of China's crude basket, driven by friendly U.S. crude grades and active term contracts.
Other notable minor suppliers include Angola, Kuwait, Canada, and Oman, which together add roughly 10-12 percentage points to China's diversification. These countries often tie their volumes to long-term equity stakes or downstream investments in Chinese refineries, reinforcing the link between oil flows and strategic capital.
Iran, Venezuela, and the "invisible" imports
Official Chinese customs data show no direct crude entries from Iranian oil or Venezuela in 2025, but market-tracking firms estimate that a significant share of Iranian and Venezuelan barrels reaches China via third-party intermediaries. Kpler-type analytics suggest that about 17 percent of Chinese crude may ultimately originate from Iran and Venezuela combined, even if it is booked under Malaysian, Russian, or other flags.
This pattern reflects sanctions-driven trade routes, where Chinese buyers pay discounts for quality-adjusted crude but obscure the origin to avoid compliance risks. As a result, the "official" list of suppliers understates both the geopolitical risk and the pricing flexibility embedded in China's import mix.
How China's oil imports changed over time
Between 2020 and 2025, China's oil import structure underwent three clear shifts: the rise of Russia, the relative decline of Saudi Arabia, and the emergence of Malaysia and Brazil as regular top-five suppliers. In 2020, Russia's share was about 14-15 percent, while Saudi Arabia held around 16-17 percent; by 2025, the positions had effectively reversed.
A key driver has been price differentials in oil markets: Russian Urals and Eastern Siberian Light crude have frequently traded at $10-25 per barrel below benchmark grades, making them attractive to Chinese refiners. At the same time, Middle Eastern producers have tightened their discounts, reducing their competitive edge in the Chinese market.
- Step 1: Russia extends term contracts with major Chinese refiners such as CNPC and Sinopec in 2021-2022, locking in multi-year volumes.
- Step 2: China expands rail and pipeline capacity from Siberia, increasing the maximum practical flow of Russian crude by around 30 percent between 2022 and 2024.
- Step 3: Saudi Arabia and other Gulf states adjust their pricing strategies, but cannot match the persistent discount on Russian barrels, costing them market share.
Why supplier diversity matters
China's policymakers emphasize energy security as a core national-interest objective, which explains why they maintain a broad supplier base rather than concentrating on one or two countries. Diversification guards against disruptions from regional conflicts, sanctions, or choke-point closures in the Strait of Hormuz or the Malacca Strait.
At the same time, state-owned enterprises such as CNPC, Sinopec, and CNOOC have built a global portfolio of upstream assets, including stakes in Russian, Iraqi, and Brazilian fields. These equity barrels often arrive at preferred prices, effectively lowering China's average import cost and insulating it from short-term spot-market spikes.
