Agreement on Basic Principles and elaboration of Karabakh conflict peace resolution acceptable for the three sides [Armenia, Russia, Azerbaijan] is still a prior issue, OSCE Chairperson-in-Office, Lithuanian FM Audronius Azubalis told at an interview with Azerbaijani Trend agency.

OSCE is ready to support the trilateral negotiation format between Armenian, Russian and Azerbaijani presidents.

“Though the sides have not accepted any basic principles in Kazan, I am inspired that they are ready to regulate the conflict through negotiations,” Azubalis added.

According to him, Armenia and Azerbaijan should take measures on lessening intensity, finishing the exchange of captives and investigate cases on the contact line.
