"Petro Poroshenko and Francois Hollande have agreed to continue consultations in Minsk at the level of diplomatic advisers to the Heads of State within the Normandy Four format. After this, the leaders of Ukraine, France and Germany will take part in a telephone conference next week," the press service said.

What is more, the presidents of Ukraine and France agreed that the security component, which has not been fulfilled by Russia yet, is of paramount importance and must be a priority part of the road map for the implementation of the Minsk agreements.
