The parties expressed serious concern over the absence of progress in the fulfillment of the security provisions of the Minsk agreements by Russia.
Absolute priorities are consolidation of the sustainable and comprehensive cease-fire along with Russian occupation troops' withdrawal from Ukraine.
The interlocutors emphasized that Moscow must finally demonstrate political will for a peaceful settlement and agree to deploy the U.N. peacekeeping mission in the occupied Donbas, including the uncontrolled part of the Ukraine-Russia state border.
Poroshenko and Volker welcomed the liberation of the Ukrainian hostages late last year and the importance of this process completion.
They drew attention to the adoption of the Law of Ukraine on reintegration of the occupied territories as an element of the common strategy on the restoration of sovereignty and territorial integrity of Ukraine.
The parties stressed the priority of peaceful, political and diplomatic settlement of the situation in the Donbas.

The parties are going to discuss the conflict in Ukraine's east, the prospects for the peacekeeping mission deployment and its possible format.
