Volodymyr Zelensky has said Ukrainian and US officials will meet for peace talks in Saudi Arabia next Monday, after the Kremlin confirmed US-Russia talks there the same day.
Ukraine's leader said Russian President Vladimir Putin "must stop making unnecessary demands that only prolong the war". Moscow's demands include a complete end to military assistance for Ukraine.
Zelensky also warned that taking Nato membership for Ukraine off the table - something Putin has said was non-negotiable for peace - would be a "big gift to Russia".
He also rebuffed claims by the White House that he discussed ceding ownership of Ukraine's nuclear power plants to the US during a call with President Donald Trump.
