Volodymyr Zelenskyy says the US has agreed to offer “strong” security guarantees to Ukraine for 15 years, but acknowledged that the future of the country’s eastern Donbas region was unresolved after his two-hour meeting on Sunday with Donald Trump in Florida.

Speaking on his way back to Europe, Zelenskyy said the US Congress and Ukraine’s parliament would jointly vote on American pledges. These were a key part of a 20-point peace plan discussed with the US president at his Mar-a-Lago residence, he said.

The guarantees are seen by Kyiv as crucial to deter further Russian aggression in the event of a peace deal. Zelenskyy admitted that previous promises – including the US and UK-backed 1994 Budapest memorandum guaranteeing Ukraine’s borders – “did not work”.
