Russia regrets Armenia's participation in NATO summit

Russia "deeply regrets" Armenia's participation in the NATO summit in Washington, Russian Deputy Foreign Minister Mikhail Galuzin said on Thursday.

"Speaking about the security sphere, I would like to emphasize that Armenia remains a member of the CSTO and is a party to numerous bilateral agreements in the military and military-technical spheres," he told RIA Novosti.

"Instead of a constructive approach to discussing Yerevan's concerns, they have unfortunately taken a different path," the Russian official added.
