UK sanctions Slavneft and Rosneft’s Vostok Oil project, saying all ten of Russia’s top oil producers are now targeted

The United Kingdom announced a new package of sanctions on Russia on 12 November 2026, adding the oil producer Slavneft to its list and saying this makes Britain the first country to have sanctioned all ten of Russia’s major oil producers. The UK government made the announcement as Prime Minister Andy Burnham arrived at the European Political Community summit in Dublin.

According to the Prime Minister’s Office, the package also covers shadow fleet vessels involved in transporting Russian oil and liquefied natural gas, major coal companies, and Rosneft’s flagship Arctic oil and gas project, LLC Vostok Oil. London says the measures target nearly every part of the energy revenue chain, from producers and trading networks to supply chains and ships, with the aim of limiting Russia’s ability to earn money to finance what the UK government calls an illegal war.

Pressure while talks continue

The sanctions were presented as a response to the situation after this week’s peace talks in Abu Dhabi, which Geopolitiki has reported in Abu Dhabi: trilateral talks end with agreement on a large prisoner exchange – Umerov: “significant differences remain”. In the UK statement, Burnham said that talks on Ukraine had progressed but that “now is not the time for complacency”, and that partners must keep raising pressure on Russia to agree a full and immediate ceasefire.

The Prime Minister is expected to ask leaders from around 50 countries at the summit to keep up the pressure on President Vladimir Putin so that Moscow approaches negotiations seriously.

According to the UK government, Burnham is due to co-chair a small group meeting on Ukraine with President Volodymyr Zelensky, and will stress the need for robust and legally binding security guarantees for Ukraine as part of any peace process, continued negotiations with European delegations, and support for Zelensky’s call for a full and immediate ceasefire.

Drone boats and a defence roundtable

The same announcement said the Ukrainian drone firm UForce is creating hundreds of skilled jobs and 60 apprenticeships in the UK as it sets up new factories. The UK government said it was announced on board HMS Prince of Wales on the morning of 12 November, and that more than 70% of the content of each UK-built drone boat will come from British suppliers.

At the summit Burnham is also expected to co-chair a defence and security roundtable with Danish Prime Minister Mette Frederiksen. According to the UK statement, leaders are due to discuss Europe’s response to an increasingly difficult threat picture, particularly hybrid threats, and to seek a coordinated approach.

All claims about the purpose and effect of the sanctions are those of the UK government; the statement does not list the individual vessels or companies, and no Russian response was available in the material reviewed.
