Foreign ministers of Ukraine, Russia, Germany and France, who recently met in Normandy format in Berlin, have agreed that Trilateral Contact Group (Russia, the OSCE, the Kyiv authorities and representatives of Ukraine's south-eastern regions) must hold a meeting to implement Minsk Agreements that in turn would be a pledge of the further presidential meeting in Astana, spokesman of the Ukrainian Foreign Ministry Yevhen Perebyinis said.

"The ministers called a Trilateral Contact Group to meet in coming days to reach a progress in a full implementation of the Minsk agreements, including designation of the conditions for efficient ceasefire, achievement of the agreements on the conditions on humanitarian aid supply and continuation of the liberation of hostages," Perebyinis quotes a joint statement made for press on the outcome of the Berlin meeting.

According to the document, a probability of the presidential meeting in Astana depends on how fruitful a meeting of the Trilateral Contact Group would be.

"It would be a contribution on the way to successful high level meeting in Astana. The ministers agreed that a further work must be done to reach this goal," the ministry's spokesman quotes the statement.

The document said that foreign chiefs had a vivid discussion over the search for political ways of resolving a situation in Ukraine and a probability of the meeting between the leaders of the states in Astana.

The ministers confirmed a firm support for a swift and overwhelming peaceful solution of today's crisis, including constant political process. "The ministers agreed that Minsk Agreements are that very way for resolving the conflict so that they should be fulfilled by all parties in a full scale. They [foreign chiefs] also agreed that a silence regime must be maintained in full," he said.
