PARIS, January 26. /TASS/. Wednesday’s Normandy Format talks were not smooth, but frank, Deputy Chief of Staff of the Presidential Executive Office Dmitry Kozak said after the meeting of political advisers to the leaders of the Normandy group (Russia, Germany, France and Ukraine).

"We had a tough conversation, but maybe, the first straightforward conversation, in order to take inventory of all the problems connected to the implementation of the Minsk agreements," he said.

According to Kozak, the next round of talks of the Normandy Format political advisers will take place in Berlin in two weeks.

"As for the other issues, we took inventory of those discrepancies, various interpretations of the Minsk accords. It is not a secret they exist. And we [agreed] to hold additional internal consultations both in Ukraine and by other representatives of the Normandy Format in order to meet in Berlin in two weeks and to attempt to find solutions to all those problems, which, regrettably, have not been resolved for a very long time - for seven years," he said.
