US President Donald Trump on Thursday called on Ukraine to move "quickly" on a deal to end the war with Russia. Trump's warning comes ahead of fresh talks expected in Miami, Florida on the weekend.

President Donald Trump on Monday described an end to the war in Ukraine as closer than ever, with American officials earlier in the day suggesting beefed-up security guarantees for Kyiv had advanced the peace talks — but that the US offer would not be on the table forever.

KYIV, Ukraine -- KYIV, Ukraine (AP) — President Donald Trump on Sunday claimed Ukrainian President Volodymyr Zelenskyy “hasn’t read” a U.S-authored peace proposal aimed at ending the Russia-Ukraine war.

Even as Ukraine’s Zelenskyy has accepted a modified version of US-brokered peace proposal to end the war, there are signs that the almost four-year war might not be nearing its end. Russia’s Putin has reportedly rejected the proposal Europe and Ukraine agreed on in Berlin recently.

The president said he had exchanged “pretty strong words” with European leaders, while Russia signaled it saw itself as increasingly on the same page as the U.S.

Russian President Vladimir Putin gave a clear indication Wednesday that he will not compromise on his demands for Ukraine to cede territory despite US President Donald Trump’s intensifying push for peace.

The comments from Trump's oldest son are a sign of growing frustration over the failure of the Ukraine peace efforts to end the war
