Russia, the U.S. and France, the co-chairs of the OSCE Minsk Group that deals with the settlement of the Nagorno-Karabakh conflict, have expressed deep regret at the fact that the parties were not able to find a solution of the problem in the course of negotiations, RIA Novosti reported.
"We express our deep regret at the fact that during the negotiation process, the parties continued to seek unilateral advantages rather than trying to find a solution based on mutual interests," the presidents of the three countries Vladimir Putin, Barack Obama and Francois Hollande said in a joint statement adopted on the Nagorno-Karabakh conflict.
"We are confident that further delay in reaching a balanced framework agreement leading to a comprehensive peace settlement is unacceptable and urge the leaders of Armenia and Azerbaijan to focus on the issues that are still open with renewed energy," the document says.
