The White House said that talks in Switzerland on a proposal to end the Ukraine war marked a "significant step forward," and reaffirmed that any eventual deal would "fully uphold" Ukraine's sovereignty.
A joint US-Ukraine statement released minutes later by the US said: "As a result of the discussions, the parties drafted an updated and refined peace framework."
Secretary of State Marco Rubio led a US delegation that met with Ukrainian and European officials in Geneva yesterday to try to thrash out a plan for ending the conflict, which began in February 2022 with Russia's invasion of Ukraine.
US President Donald Trump had given Ukraine until 27 November to approve his plan to end nearly four years of fighting.
But Ukraine has sought changes to a draft that accepted a range of Russia's hardline demands, with the 28-point plan requiring the invaded country to cede territory, cut its army and pledge never to join NATO.
The statement's announcement of a new draft appeared to indicate that changes were indeed made.
"The talks were constructive, focused, and respectful, underscoring the shared commitment to achieving a just and lasting peace," the joint statement said.
"The discussions showed meaningful progress toward aligning positions and identifying clear next steps. They reaffirmed that any future agreement must fully uphold Ukraine's sovereignty and deliver a sustainable and just peace," it added.
Both sides pledged to keep working on joint proposals "in the coming days."
The White House's readout said that Mr Rubio and his team had reaffirmed the United States commitment to "ensuring that Ukraine's sovereignty, security, and future prosperity remain central to the ongoing diplomatic process."
Meanwhile, a Russian drone strike on the major Ukrainian city of Kharkiv killed four people and wounded 17 yesterday, its mayor said.
"At this moment, 17 people are known to have been wounded. Four people have died," mayor Igor Terekhov said, reporting the evening strike in a message on Telegram.

"The circumstances are truly horrible when, despite the negotiations, Russian troops are attacking civilian objects, civilian infrastructure, residential buildings, when people are dying," Mr Terekhov said.
Oleg Synegubov, head of the Kharkiv regional military administration, described the attack as "massive".
The emergency services said the drone strike on two districts of Kharkiv had caused fires and the destruction of buildings.
"Three residential buildings and an infrastructure facility were on fire," it said.
