"There are good prospects for the implementation of the Minsk agreements," Hug said adding that OSCE monitors have already held talks with the representatives of forces in the format of the Joint Control Coordination Center.
"The plans on withdrawal of heavy equipment are being elaborated," Hug added.
"By definition, a ceasefire cannot begin immediately, and especially in a vast area such as Ukraine's east," Hug noted.
Last week, the leaders of Russia, Germany, France and Ukraine negotiated a number of steps to facilitate the reconciliation process in southeastern Ukraine. The set of measures agreed in Minsk include a ceasefire from February 15, the withdrawal of heavy artillery from the line of contact and an all-for-all prisoner exchange.
