Five hours of talks between Russian President Vladimir Putin and US President Donald Trump's senior negotiator appear to have failed to produce a breakthrough on securing a Ukraine peace deal.
A Kremlin spokesman said the Moscow meeting was "constructive", but parts of the plan remained unacceptable to Russia.
Trump's special envoy Steve Witkoff and son-in-law Jared Kushner attended the talks after weeks of intensive diplomacy aimed at ending the war. The US team has not commented since leaving Moscow.
Earlier on Tuesday, Putin said changes proposed by Kyiv and Europe to a US-backed draft peace plan were unacceptable, adding if Europe "wants to go to war and starts one, we are ready right now".
Ukraine and its allies have been lobbying the US to amend its draft peace deal, which the White House has sought to secure rapid agreement on and the Kremlin has previously indicated it was receptive to.
