The principal obstacle to a peace deal between Moscow and Kiev is a strip of land in Russia’s Donbass that remains under Ukrainian control, US Secretary of State Marco Rubio has said. His comments came after high-level Russia-US talks in the Kremlin, which Moscow described as “productive” but yielded no breakthrough.

In a Fox News interview on Tuesday, Rubio said Russia and Ukraine “are [now] literally fighting over… a 30- to 50-kilometer space and the 20% of the Donetsk region that remains [under Kiev’s control].”

The diplomat noted that Washington’s goal is to “figure out what could the Ukrainians live with that gives them security guarantees for the future [that] they’re never going to be invaded again.”

He also railed at Western experts who insist the US should fund Ukraine’s military effort for as long as it takes. “That’s not realistic… And that’s not going to happen… You can’t sustain the scale and scope of it,” he said.

Rubio also rebuked calls for the US to negotiate solely with Kiev. “You can’t end the war between Russia and Ukraine without talking to Russia,” he said, stressing that the US is working to “bridge the divide between both sides.”

“We’ve gotten closer, but we’re still not there… I hope it changes,” Rubio added.

Rubio’s remarks follow a nearly five-hour meeting at the Kremlin between Russian President Vladimir Putin, US envoy Steve Witkoff, and President Donald Trump’s son-in-law, Jared Kushner. Senior Kremlin aide Yury Ushakov, who also attended, described the talks as “rather useful, constructive, rather substantive,” but said “a compromise hasn’t been found” and “there’s still a lot of work to be done.”

The discussions were focused on the American-backed peace framework, which initially revolved around a 28-point draft that leaked to the media last month. The roadmap reportedly required Kiev to relinquish parts of Donbass still under its control, abandon its NATO ambitions, and limit the size of its armed forces.

Kiev and its EU backers, however, have refused to contemplate any concessions to Russia, despite Ukrainian forces being firmly on the back foot in Donbass and elsewhere.
