Diplomats have been focused on revisions to a proposed plan developed in negotiations between Washington and Moscow.

Helping Ukraine defeat Russia is a cheaper prospect for Europe than giving into the Kremlin’s concessions, according to a new study titled “Europe’s Choice” out of Norway.

The team of Ukrainian negotiators began meeting Sunday morning with Rubio, Special Envoy Steve Witkoff and Jared Kushner, President Trump's son-in-law.

Russian President Vladimir Putin said the outlines of a draft peace plan agreed by the U.S. and Ukraine could become the basis of a deal to end the war.

Russia will make no big concessions on a peace plan for Ukraine, a senior Russian diplomat said on Wednesday, after a leaked recording of a call involving U.S. envoy Steve Witkoff showed he had advised Moscow on how to pitch to Donald Trump.

US secretary of state Marco Rubio said talks with Ukrainian officials in Florida on a White House peace plan were productive but there is more work to be done.
