The Collective Security Treaty Organization (CSTO) acted strictly in accordance with its statutory documents in the situation surrounding Nagorno-Karabakh, stated Valentina Matvienko, Speaker of the Federation Council of the Russian Federal Assembly.

According to her, Yerevan is unreasonably resentful of the CSTO for this position and is attempting to shift responsibility onto others.

"Unfounded resentment of the CSTO during the war between Armenia and Azerbaijan is, in my opinion, an attempt to shift responsibility for Karabakh onto Russia, the CSTO. Under those conditions, the CSTO acted strictly in accordance with its statutory documents," Matvienko told reporters.
