• Chinese state-owned oil companies have halted purchases of Russian seaborne crude following new Western sanctions targeting Rosneft and Lukoil
  • The suspension affects a trade flow representing approximately 20% of China's total crude imports, or about 2 million barrels per day
  • Market volatility has increased as refiners scramble to secure alternative supplies while navigating potential secondary sanctions

Chinese state oil majors have suspended seaborne Russian oil purchases in response to fresh Western sanctions targeting Russian energy giants Rosneft and Lukoil, according to people familiar with the matter. The move creates immediate supply uncertainty for a trade that constitutes up to one-fifth of China's crude imports.

The suspension by companies including China National Petroleum Corp. (CNPC) comes as the U.S., EU, and UK have blacklisted Rosneft and Lukoil, mandating the wind-down of all related transactions by November 21, 2025. The decision reflects growing concerns among Chinese state enterprises about potential secondary sanctions that could cut them off from Western financial systems and global commodities markets.

"The compliance departments at state majors are taking a very cautious approach," said one source, who asked not to be identified discussing sensitive commercial matters. "They're unwilling to risk their international banking relationships for these shipments."

Oil futures spiked following the news as traders assessed the potential disruption to global supply patterns. The suspension threatens to upend a crucial energy relationship that had flourished since Western sanctions began following Russia's invasion of Ukraine in 2022.

China's Foreign Ministry has repeatedly criticized what it calls "illegitimate" unilateral sanctions, but state-owned enterprises appear to be prioritizing business continuity over political solidarity. The suspended purchases specifically affect seaborne shipments, which are more exposed to Western financial and insurance networks than pipeline deliveries to northern China that continue under government-sanctioned contracts.

Private refiners in Shandong province, particularly those with less international exposure, may continue purchasing discounted Russian crude, though they face their own challenges securing shipping and insurance. Similar regulatory dilemmas are playing out in India, another major importer of Russian oil now weighing the risks of secondary sanctions.

Efforts to reach CNPC and other state oil majors for official comment were unsuccessful. Market participants are watching whether the suspension proves temporary while companies assess legal exposure, or marks a more fundamental shift in China-Russia energy trade dynamics.

Correction: An earlier version of this article misstated the percentage of China's crude imports affected. The correct figure is approximately 20%.
