A contentious meeting between President Trump and President Volodymyr Zelensky of Ukraine produced no obvious progress toward a cease-fire.

President Donald Trump says it's possible that Ukraine can defeat Russia, but he’s doubtful that it will happen.

But Russian Foreign Minister Sergei Lavrov on Tuesday dismissed the idea of halting the conflict at the current contact line. Moscow was only interested in "long-term, sustainable peace", Lavrov said, implying that freezing the front line would only amount to a temporary ceasefire.

The president suggested Ukraine would need to cede territory in the Donbas region as part of his proposed ceasefire deal with Russia.

President Donald Trump told reporters on Sunday thatthe Donbas region of Ukraine should be “cut up," leaving most of it in Russian hands, to end the war.

Ukrainian President Volodymyr Zelensky said U.S. President Donald Trump reneged on the possibility of sending the long-range missiles to Ukraine, which would have been a major boost for Kyiv.
