Sri Lanka, Dec. 29 -- The US has offered Ukraine security guarantees for 15 years, Volodymyr Zelensky has said, during talks on a revised peace plan with Donald Trump in Florida on Sunday.

The US president said an agreement on this point was "close to 95%" done, but Ukraine's leader has since said he would like guarantees for up to 50 years.

President Zelensky outlined territorial issues and the Russian-occupied Zaporizhzhia nuclear plant as the last unresolved matters, with little said on the future of Ukraine's contested Donbas region.

Russia has previously rejected key parts of the plan, but a Kremlin spokesman agreed on Monday with Trump's assessment that peace is closer, Russian-owned news agency Tass reported.
