"The Russian Federation regrets Yerevan's participation in the NATO summit held in Washington,” Mikhail Galuzin, Deputy Minister of Foreign Affairs of Russia, told RIA Novosti, Paralel.Az reports.

He said that instead of a constructive approach to discuss Armenia's concerns, they unfortunately chose another way.

The Deputy Minister of Foreign Affairs noted that by deepening cooperation with NATO, Yerevan risks harming its own security by seriously disrupting the situation in the South Caucasus with its own hands.
