Over 20 nations supporting Ukraine have pledged to isolate Russian oil and gas markets globally as an additional step toward exerting pressure on Moscow. This announcement was made at a “Coalition of the Willing” summit hosted by UK Prime Minister Keir Starmer and Ukrainian President Volodymyr Zelenskyy in London on October 24, 2025, attended by Ukrainian President Volodymyr Zelenskyy and UK Prime Minister Keir Starmer respectively, to “choke off funding for Russia’s war machine” while intensify sanctions against Moscow (The Guardian).
Coordinated Sanctions by Western Allies

This pledge follows recent sanctions imposed by the United States, United Kingdom and European Union. The US sanctioned Russia’s two largest oil companies — Rosneft and Lukoil — with U.S. assets being frozen off and significant transactions banned; whilst EU introduced their 19th sanctions package which includes a phased ban on Russian LNG imports with all imports ceasing by January 2027.
Prime Minister Starmer stated that the coalition’s actions are intended to “choke off funding for Russia’s war machine”, signaling an effort by all members to weaken Russia’s economy in support of its military activities.
The Independent Ukraine Perspective and Strategic Objectives.

President Zelenskyy highlighted Russia’s attack on Ukraine’s energy infrastructure as being intended to create “winter cold”, forcing civilians into poverty and pressuring Ukraine into submission. He stressed the necessity for increased sanctions on Russian oil as well as increased domestic air defense production and long-range missile purchases as well as using frozen Russian assets to fund defense and reparations funds in Ukraine.

Global Repercussions and Energy Market Dynamics

Coordinated sanctions have already had an impactful ripple effect across global energy markets. China and India, who formerly consumed most of Russia’s oil exports, have significantly reduced imports following U.S. sanctions, leading to rising oil prices as well as prompting concerns over energy supply security in Asia.

Political and Diplomatic Aspects

These sanctions have won widespread support among Western allies, but have caused diplomatic tension within the European Union. Countries like Slovakia and Hungary have raised concerns regarding energy security and economic impact of Russia gas import ban. As a result, these nations are seeking alternative energy sources or compensatory mechanisms to ease any effects caused by sanctions.

Prognosis and Future Steps taken.

The coalition’s decision to remove Russian oil and gas from global markets marks an intensification of economic confrontation with Russia. As this situation develops, additional sanctions and diplomatic efforts may continue shaping geopolitics; their success depends on sustained international cooperation as well as managing any challenges caused by sanctions.
