The next round of talks aimed at ending the war between Russia and Ukraine will take place next week in Abu Dhabi.
US special envoy Steve Witkoff said on Monday that Washington will mediate "working-level negotiations" between Kyiv and Moscow with the aim of "advancing President [Donald] Trump's mission to end the war".
"Discussions will focus on post-war security arrangements, de-escalation, humanitarian efforts, and next steps toward peace," he said in a post on X.
Mr Trump has assigned Mr Witkoff to mediate in the conflict. US negotiators will also meet this week in Brussels with representatives from France, Germany, the UK, the EU and Nato to discuss "security guarantees for Ukraine, Europe’s post-war security architecture and economic opportunities to support Ukraine’s reconstruction", the special envoy added.
"We look forward to building on the progress made in Kyiv, Oslo and St Petersburg toward a comprehensive, durable peace agreement that delivers lasting security for generations to come," Mr Witkoff said.
The talks come amid a complicated moment in US relations with both Ukraine and Russia.
Mr Trump campaigned on a promise to quickly end the war, now approaching its fifth year. The US President has met both Ukrainian President Volodymyr Zelenskyy and Russian President Vladimir Putin. Mr Putin travelled for a summit with Mr Trump in Alaska in August last year.
The talks come after Mr Trump ordered a sanctions waiver for Russian diesel amid a worsening global energy crisis.
He had, only weeks before, signed into law a sanctions regime that raised duties on Russian goods imported into the US by up to 500 per cent, and a separate requirement to place tariffs of up to 100 per cent on China, India and other top buyers of Russian energy.
Mr Witkoff met Mr Putin late last month and described him as a "humanitarian".
US relations with Kyiv, meanwhile, are strained, as Mr Trump has urged Ukrainian leaders to stop attacks on Russian oil depots.
“I think it’s time for Ukraine to get a new president,” Mr Trump told reporters at the White House a few weeks ago.
But Mr Trump did say he would be willing to invite Mr Zelenskyy to the next Group of 20 summit in Florida next month.
