Former Ukrainian President, currently Ukraine's envoy to the Trilateral Contact Group on Ukraine Leonid Kuchma has met with U.S. special envoy Kurt Volker to discuss the situation in Donbas and the prospects of further contacts.

"The meeting participants discussed the settlement of the situation in Donbas. Leonid Kuchma noted the role and active position of the U.S. in the settlement of the Donbas situation and thanked him for the principled position and support of Ukraine's territorial integrity and sovereignty," Darka Olifer, press officer for Kuchma, said on Facebook on Monday, attaching a relevant photo.

The meeting participants stressed that a steady lasting ceasefire and the solution of the entire range of security issues is a key thing "without which there can be no progress in the settlement of humanitarian, political and social issues."

"The parties agreed to maintain further contacts on a permanent basis," Olifer said.

U.S. Secretary of State Rex Tillerson appointed former U.S. envoy to NATO Kurt Volker special representative on Ukraine on July 7.
