Russian President Vladimir Putin said on Friday that Russia is always open to negotiations, and if Kyiv is ripe for talks, then mediation efforts of those who offer would be required.
He made the remarks at a news conference in the Kazakh capital Astana where he's attending meetings with regional leaders.
Putin said that Ukraine was not prepared for negotiations and thanked Turkish President Tayyip Erdogan for his role in brokering prisoner exchanges.
According to an early report carried by Interfax news agency on Friday, Russia's Deputy Foreign Minister Sergei Ryabkov said there had been no new signals on a potential prisoner exchange with the U.S. yet.
Russia said in August it was ready to discuss a prisoner swap involving Brittney Griner, a U.S. basketball star who was jailed for drug offense in Russia in August, but neither side has reported progress since then.
When asked if he had regrets about Russia's special military operation in Ukraine, Putin told reporters that Russia is doing the right thing, adding that it's not Russia's objective to destroy Ukraine.
