Donald Trump has said he did not want a "wasted meeting" after a plan to have face-to-face talks with his Russian counterpart Vladimir Putin about the war in Ukraine were put on hold.

Axar.az informs, citing BBC, the US president indicated that a key sticking point remained Moscow's refusal to cease fighting along the current front line, in remarks at the White House on Tuesday.

Earlier, a White House official had said there were "no plans" for a Trump-Putin meeting "in the immediate future", after Trump said on Thursday that the two would hold talks in Budapest within two weeks.

Key differences between US and Russian proposals for peace became increasingly clear this week, appearing to have dashed chances of a summit.

A preparatory meeting between US Secretary of State Marco Rubio and Russian Foreign Minister Sergei Lavrov was due to be held this week - but the White House said the two had had a "productive" call and that a meeting was no longer "necessary".
