A "tremendous amount of progress" has been achieved in talks to finalise a US-proposed peace plan to end the Russia-Ukraine war, Secretary of State Marco Rubio has said.
But "there's still some work to be done", Rubio said after meeting Ukrainian and European negotiators in Geneva, Switzerland.
Ukrainian President Volodymyr Zelensky said there were "signals that President [Donald] Trump's team is hearing us".
Ukraine and its European allies had expressed concern over the leaked proposals, seen as favouring Russia and welcomed by Vladimir Putin as "the basis" for settlement. Zelensky had said Ukraine "might face a very difficult choice: either losing dignity, or risk losing a key partner".
Speaking to reporters late on Sunday, Rubio said the negotiating teams in Geneva had had a "very good day".
