At least four Chinese supertankers are delivering Russian Urals crude oil to China after the European Union and G7 countries imposed a price ceiling on energy from Russia, Reuters reports. According to the agency, another vessel was heading to India.

According to Reuters’ sources, all five shipments were scheduled for the period from December 22 to January. Despite Western sanctions, China and India continue to buy Russian oil at a discount, the agency writes.

The price restrictions, which came into effect in December, allow non-EU countries to import oil from Russia, but prohibit the provision of insurance, ships and any services for the transportation of sea shipments of Russian crude unless the contracts for its sale include a $60-a-barrel price cap clause.

“Given that Urals crude prices are well below the price cap, Urals trade is essentially legal,” said a senior executive of a Chinese firm involved in the shipments.
