The United Kingdom's push to broker peace in the Russia-Ukraine conflict suffered a major blow this week as the United States abruptly pulled high-level participation from a planned summit in London, downgrading the talks and dimming hopes for a diplomatic breakthrough.

The meeting, originally scheduled for Wednesday and expected to convene foreign ministers from the UK, France, Germany, Ukraine, and U.S. Secretary of State Marco Rubio alongside Special Envoy Steve Witkoff, was reduced to a technical discussion among lower-level officials after the U.S. delegation withdrew hours before the event. The UK Foreign Office confirmed the ministerial-level talks were canceled, with the revised meeting closed to the media.

UK Foreign Secretary David Lammy met separately with Ukrainian counterpart Andrii Sybiha, reaffirming Britain's commitment to diplomacy. However, the U.S. absence and its description of the talks as mere "technical meetings" underscored a setback for London's ambitions to lead progress in the stalled peace process.

Rubio contacted Lammy Tuesday night, expressing optimism about the discussions and signaling plans to visit the UK soon. In a statement on X, Rubio called the meetings "substantive" and said he looked forward to following up. Meanwhile, Rubio and Witkoff shifted focus to upcoming talks in Moscow, where Witkoff is set to meet Russian President Vladimir Putin for the fourth time. U.S. envoy Keith Kellogg represented Washington in London.

The downgrade follows U.S. President Donald Trump's warning that Washington could abandon the talks if they fail to produce results by April's end. Ukrainian advisor Andriy Yermak, speaking in London, emphasized Kyiv’s commitment to peace, noting Wednesday’s agenda would focus on an unconditional ceasefire while deferring long-term post-conflict issues.

The London talks follow a similar summit in Paris last week, where U.S. and European officials discussed concessions needed from both Kyiv and Moscow, according to Reuters. European leaders remain steadfast on territorial disputes, with French Foreign Minister Jean-Noel Barrot insisting Tuesday that Russia’s claim to Crimea is unacceptable and the territory must return to Ukraine.

As the U.S. sends mixed signals and diplomatic efforts continue, prospects for a swift resolution grow increasingly uncertain. (ILKHA)
