UK becomes first country to sanction all 10 of Russia's largest oil producers

The British government announced the latest measures on November 12, as Prime Minister Andy Burnham attended the European Political Community summit in Dublin.

The new sanctions include Russian oil company Slavneft, completing Britain's sanctions coverage of the country's 10 largest oil producers.

The package also targets vessels in Russia's shadow fleet used to transport oil and liquefied natural gas, major coal companies, and Vostok Oil, Rosneft's flagship Arctic oil and gas project.

According to the British government, the measures are designed to target nearly every stage of Russia's energy revenue chain, from oil and gas production to trading networks, supply chains and shipping.

The announcement comes after two days of US-mediated negotiations between Ukraine and Russia in Abu Dhabi, which ended without a breakthrough toward ending the war.

"Peace talks on Ukraine have progressed but now is not the time for complacency — we must continue to ramp up pressure on Russia to agree a full and immediate ceasefire," Burnham said.

"That is why the UK has announced a sweep of stinging new sanctions to turn the screws on Russia's oil revenues and drive forward an end to the Kremlin's needless war."

At the Dublin summit, Burnham was expected to co-chair a meeting on Ukraine with President Volodymyr Zelenskyy and urge European leaders to maintain pressure on Moscow.

The British government said it would continue pushing for European participation in peace negotiations, legally binding security guarantees for Ukraine, and a full and immediate ceasefire.

The announcement did not specify how much Russian energy revenue the new sanctions were expected to restrict.
