The US has held talks with Russia, and separately with Kyiv and European leaders, on various different drafts of a plan for ending the war in Ukraine, but no deal has yet been reached despite Trump’s repeated promises to clinch one.

“If both sides want to solve this, we’re going to get it solved,” Witkoff told an audience at the World Economic Forum in Davos.

“I think we’ve made a lot of progress,” he added.

US President Donald Trump a day earlier told the Davos forum that the leaders of Russia and Ukraine would be “stupid” if they failed to come together and get a deal done.

Witkoff said he was headed to Moscow later in the day.

He spoke in an impromptu appearance a breakfast meeting on the future of Ukraine, with panelists including Nato secretary Mark Rutte and Finnish President Alexander Stubb.

Rutte expressed confidence that Trump was committed to Ukrainian independence and sovereignty. “I have never doubted this,” Rutte said.

“What we need is to keep our eyes on the ball of Ukraine. Let’s not drop that ball”, he added.
