"It was agreed that all actors will undertake all necessary measures aimed at achieving … the speedy de-escalation of ongoing hostilities in the conflict zone, in particular in the vicinity of the towns of Debaltseve and Mariupol, which have seen the heaviest fighting in recent days," the statement read.
The Trilateral Contact Group will carry out consultations on a regular basis with Donbas representatives aiming at the full implementation of the Minsk Agreements, it was said in the statement.
The parties stressed the necessity of full respect of the ceasefire, which is due to come into force at midnight local time on February 15 (February 14, 10:00 p.m. GMT).
The ceasefire was one out of the measures agreed on during the last reconciliation talks on Ukraine in the Belarus capital of Minsk.
The leaders of Ukraine, France, Germany, and Russia held a 16-hour summit in Minsk on Wednesday and early Thursday. The talks resulted in a new political deal aimed at stopping the deadly conflict in eastern Ukraine.
The deal was signed by the Contact Group on Ukraine, including envoys from Moscow, Kiev, the self-proclaimed people's republics of Donetsk and Luhansk and the OSCE.
Despite a similar ceasefire agreement signed by the parties in last September, clashes in eastern Ukraine intensified in the first weeks of 2015.
