Russia is ready to resume peace negotiations with Ukraine in Istanbul, Russian state news agency TASS cited a foreign ministry official as saying.
No face-to-face talks have taken place between the two sides since they met in the Turkish city on 23 July.
TASS quoted the official, Alexei Polishchuk, as saying that Turkish officials had repeatedly urged a resumption of the peace negotiations.
"The Russian team is ready for this, the ball is in the Ukrainian court," he said.
Ukraine rejects Russia's assertions that it is to blame for the stalled peace process, as the war nears the end of its fourth year.
At the July meeting, which lasted just 40 minutes, the Ukrainian side proposed a meeting in August between President Volodymyr Zelensky and Russian President Vladimir Putin.
The Kremlin subsequently said Mr Putin was willing to meet Mr Zelensky, but only in Moscow - a condition rejected by Ukraine.
