The United States and Ukraine have announced a revised framework for ending the Russia-Ukraine war after an earlier proposal by Washington drew criticism for being too favourable to Moscow.

US and Ukrainian officials said on Sunday that they agreed that any deal to end Russia’s war should “fully uphold” Ukraine’s sovereignty as they unveiled an “updated and refined peace framework” that was scant on details.

“Both sides agreed the consultations were highly productive. The discussions showed meaningful progress toward aligning positions and identifying clear next steps,” officials said in a joint statement following talks in Geneva, adding that the sides agreed on the need for a “sustainable and just peace”.

Washington and Kyiv also reiterated their readiness to keep working together to “secure a peace that ensures Ukraine’s security, stability, and reconstruction”, the joint statement said.

US Secretary of State Marco Rubio earlier on Sunday said the sides had made “tremendous” progress during the talks, though their joint statement offered no specifics for resolving the many thorny points of contention between Moscow and Kyiv.

Rubio said negotiators had made some changes to US President Donald Trump’s 28-point peace plan, including around the role of NATO, to narrow the differences between the sides.

“I can tell you that the items that remain open are not insurmountable. We just need more time than what we have today. I honestly believe we’ll get there,” Rubio told reporters at the US mission in Geneva.

Rubio declined to go into specifics about the amendments to the draft proposal, including whether Kyiv had agreed to compromise on key Russian demands, such as territorial concessions.

“But I can tell you, I guess, that I feel very optimistic that we can get something done here because we made a tremendous amount of progress today,” Rubio said.

Rubio’s cautiously optimistic remarks came after Trump, who has given Ukraine until Thursday to accept his 28-point plan, had earlier accused Kyiv of being insufficiently grateful for his administration’s assistance.

“UKRAINE ‘LEADERSHIP’ HAS EXPRESSED ZERO GRATITUDE FOR OUR EFFORTS, AND EUROPE CONTINUES TO BUY OIL FROM RUSSIA,” Trump posted on his social media site, Truth Social.

Shortly after Trump’s comments, Ukrainian President Volodymyr Zelenskyy said on X that he was grateful to the US and “personally to President Trump” for Washington’s assistance in repelling Moscow’s invasion.

Trump’s leaked blueprint for ending the war has caused consternation in Kyiv and European capitals due to its alignment with many of Moscow’s hardline demands, including that Ukraine limit the size of its military and give up Crimea, Luhansk and Donetsk.

Zelenskyy said in a sombre national address last week that the plan put Ukraine in the position of having to choose between “losing dignity” or “losing a key partner”.

European Commission chief Ursula von der Leyen said on Sunday that any peace plan needed to respect Ukraine’s freedom to “choose its own destiny,” including to join the bloc.

“It starts with the country’s reconstruction, its integration into our Single Market and our defence industrial base, and ultimately, joining our Union,” von der Leyen said in a statement.

Asked whether a deal could be reached by Trump’s Thursday deadline, Rubio said “we want to get this done as soon as possible”.

“Obviously, we would love it to be Thursday,” he said.

Rubio said the peace plan was a “living, breathing document” and would continue to change.

The top US diplomat also said the deal would need to be presented to Moscow for its approval.

“Obviously, the Russians get a vote here,” he said.
