A trilateral contact group consisting of representatives of Ukraine, Russia and the OSCE should resume its work before July 5 in order to reach agreement on establishing the regime of a bilateral ceasefire in eastern Ukraine.
German Foreign Minister Frank-Walter Steinmeier said this at a press conference after a meeting with his counterparts from France, Russia and Ukraine in Berlin on Wednesday, a Ukrinform correspondent in Germany reported.
"We have reached a common understanding that the trilateral contact group should resume its work before July 5 to hold negotiations with those responsible for the establishment of a bilateral ceasefire," he said.
He said that the foreign ministers of Germany, France, Russia and Ukraine on Wednesday adopted a joint declaration in which all sides recognize the importance of establishing a truce between the parties to the conflict in eastern Ukraine, outline key measures that are necessary for its achievement, and promise to make every effort to influence the conflicting parties.
Steinmeier noted that if the agreement on a bilateral ceasefire is reached, its observance by both sides should be controlled by OSCE observers.
In a joint statement, the ministers stressed the need to improve control over the Ukrainian-Russian border and welcomed in this regard Moscow's readiness to allow Ukrainian border guards and OSCE monitors to the territory of two Russian checkpoints.
The negotiators also emphasized the importance of providing security guarantees for reporters working in the conflict zone.
