US envoy Steve Witkoff led a team of representatives in talks in Florida on Saturday with Kremlin envoy Kirill Dmitriev and described the discussions as “productive and constructive”.

The US has been spearheading diplomatic efforts to end the war, launched nearly four years ago by the Kremlin’s invasion of its smaller neighbour.

Witkoff has singled out the question of territory as the key to making progress in the negotiations, with Kyiv rejecting Moscow’s demand that it cede all of the Donbas region, including areas its army has not captured.

Kremlin foreign policy aide Yuri Ushakov said this week that land was not the sole key issue under discussion but did not identify other unresolved issues.
