Russian President Vladimir Putin said Monday he is open to the possibility of bilateral talks with Ukraine for the first time in years, as pressure from the United States builds on both sides to agree to a quick peace deal, CNN reported.

U.S., European and Ukrainian officials are set to meet this week in London after Washington warned that it could abandon its efforts to end the conflict if there were no signs of progress.

Speaking to reporters, Putin said it could be possible to discuss the halting of strikes against civilian infrastructure directly with Kyiv.

“We have a positive attitude towards a ceasefire,” Putin also said, referencing Russia’s decision to implement a surprise 30-hour Easter truce, which both sides accused each other of violating.

“That is why we have always said that we take a positive attitude to any peace initiatives,” Putin said. “We hope that the representatives of the Kyiv regime will feel the same way.”
