“They approved it,” Andrei Purgin told journalists, answering a question whether the document was ratified.
According to Purgin, a working group for the implementation of Minsk agreements will be formed later on Saturday. The group will work closely with the Organization for Security and Co-operation in Europe (OSCE), he said.
The measures include a ceasefire between Kiev forces and independence supporters in eastern Ukraine, the creation of a buffer zone between the two sides through the withdrawal of heavy weaponry from the region and an all-for-all prisoner exchange.
The ceasefire comes into force at midnight local time on February 15 (February 14, 22:00 GMT).
