OSCE Secretary General Lamberto Zannier has expressed concern over the lack of progress in Narogny Karabakh conflict settlement.

“There is an increasing concern there because the frustration seems to be increasing,” Zannier said on the sidelines of the 2012 OSCE Security Days conference in Vienna on Monday, June 25.

“There have been very robust efforts, political efforts to really try to move things forward. The sides have been very close to agree to a set of common principles on the basis of which they could build a solution… But it’s not moving,” Zannier said.

“It is really one of those issues where you wonder whether it’s about the [OSCE conflict mediation] mechanism or whether the sides are not ready to take steps and make decisions that involve certain compromises,” he said.

“Working with the public opinion and political forces in both countries is “one way of strengthening the ability of leaders to make these difficult decisions,” RIA Novosti quoted OSCE Secretary General as saying.
