US Secretary of State Marco Rubio says talks with Ukraine over a deal to end the Russia-Ukraine war were productive, but there's "more work to be done".
The talks, held in Florida, were attended by a Ukrainian delegation led by national security council secretary Rustem Umerov, Ukraine's new chief negotiator.
Also at the meeting were President Donald Trump's envoy Steve Witkoff and Trump's son-in-law, Jared Kushner. Witkoff is due to visit Moscow for talks next week.
Umerov was brought in to replace the Ukrainian president's top negotiator, Andriy Yermak, after he quit following an anti-corruption raid on his home.
Sunday's meeting is the latest step in two weeks of intense diplomatic activity.
