Volodymyr Zelensky has thanked the “American people” and leadership and held out hope for “strong relations”, the day after an astonishing clash with Donald Trump left many uncertain where the once staunch allies stood.

Ukraine had walked into a meeting at the White House on Friday prepared to sign a mineral deal with the US, hoping it would be a step towards a just ceasefire, but left empty-handed.

In a series of posts on X on Saturday, the Ukrainian president said his people are “very grateful to the United States for all the support”, and specifically thanked Mr Trump and Congress alongside the “American people”.

“We want only strong relations with America and I really hope we will have them.”

The shouting match that unfolded in the final minutes of the meeting between the two leaders at the Oval Office on Friday seemed to dash, at least for now, Ukrainian hopes that the US could be confirmed as a reliable partner in helping to fend off, and conclude, Russia’s three-year onslaught.

The exchange saw the frustrated Ukrainian president lectured by Mr Trump and vice president JD Vance over what they saw as his lack of gratitude for previous US support.

“You’re gambling with millions of people … You’re gambling with World War Three,” Mr Trump told Mr Zelensky of his attempts to resist the Russian invasion.

It delighted officials in Moscow who saw it as a final breakdown in relations between Washington and the Ukrainian leader.

The meeting on Sunday will include leaders from France, Germany, Denmark, Italy, the Netherlands, Norway, Poland, Spain, Turkey, Finland, Sweden, the Czech Republic and Romania, as well as the Nato secretary-general and the presidents of the European Commission and the European Council.

French President Emmanuel Macron told Portugal’s RTP news channel: “If anyone is gambling with World War Three, his name is Vladimir Putin.

“My hope is that the United States of America will continue to stand by its history and its principles. Whenever we have had major conflicts, the United States of America has been on the right side of history and freedom.”
