Ukrainian President Petro Poroshenko has said he will meet his Russian counterpart, Vladimir Putin, next week to discuss the conflict in eastern Ukraine.
Speaking in the eastern city of Kharkiv, Poroshenko said the talks would take place in Milan, where a Europe-Asia Meeting summit will be held on October 16-17.
He added that German Chancellor Angela Merkel, Italian Premier Matteo Renzi, and British Prime Minister David Cameron will attend the meeting.
"You know, I don't expect that these will be easy negotiations," Poroshenko said. "But I'm an optimist."
Putin and Poroshenko last met in August for talks that led to a September 5 truce accord between Kyiv and the pro-Russian separatists.
The six-month conflict has killed more than 3,300 people. More than 300 people have died since the cease-fire was declared.
