Ukraine has significantly amended the US “peace plan” to end the conflict, removing some of Russia’s maximalist demands, people familiar with the negotiations said, as European leaders warned on Monday that no deal could be reached quickly.

Volodymyr Zelenskyy may meet Donald Trump in the White House later this week, sources indicated, amid a flurry of calls between Kyiv and Washington. Ukraine is pressing for Europe to be involved in the talks.

They say there can be no recognition of land seized by Russia militarily, and that Kyiv should make its own decisions on whether to join the EU and Nato – something the Kremlin wants to veto or impose conditions on. Ukraine’s first deputy foreign minister, Sergiy Kyslytsya, told the Financial Times such issues had been “placed in brackets” for Trump and Zelenskyy to decide upon later.
