The European Union has proposed new measures to crack down on sanctions evaders to try limit Russian trade profits from funding the war in Ukraine.

EU Commission President Ursula von der Leyen said the proposals would have a “major deterring effect” as she laid out plans for the eighth package of sanctions against Russia. The measures include preparing the legal groundwork for an oil price cap.

The EU will introduce a seaborne Russian crude oil import ban from 5 December and for oil products two months later under existing agreed plans.
