Ukraine's President Volodymyr Zelensky returned to the White House on Monday to meet US President Donald Trump for fresh talks aimed at ending the war in Ukraine.

Several European leaders also upended their plans to attend the meeting, days after Trump met Russia's President Putin in Alaska for a summit that failed to yield a ceasefire.

Here are the key takeaways from the talks in Washington.

Given his acrimonious last visit to the Oval Office in February, the Ukrainian president went to considerable lengths to be collegial and charm his American hosts - including a flurry of six "thank yous" within the first few minutes of the meeting.

The last time he was at the White House, Zelensky was scolded by Vice-President JD Vance for a perceived lack of gratitude for US support for Ukraine during the war.
