Vladimir Putin and Steve Witkoff met for the fourth time on Friday in the Russian capital Moscow.
It was a three-hour long conversation that was constructive and very useful, says Putin's foreign policy adviser Yuri Ushakov according to AFP.
It was a discussion about the possibility of resuming direct negotiations between representatives of Russia and Ukraine.
Talks between Russia and Ukraine have so far mainly taken place at a lower official level. They have, among other things, concerned prisoner exchanges and Ukrainian grain exports, an agreement that Russia later withdrew from.
In an interview with American CBS, Sergey Lavrov says that Moscow wants to "fine-tune" the US proposal for an agreement regarding the war against Ukraine.
We are ready to reach an agreement, but there are still some specific elements of this agreement that need to be fine-tuned. We are engaged in just that process, says Lavrov in the interview.
Lavrov did not want to go into details about what Russia wants to "fine-tune".
