The CSTO summit, an informal meeting of the CIS leaders and, probably, the EurAsEC summit will be held in St. Petersburg on December 6, reports RIA Novosti with reference to the press secretary of the Russian President Dmitry Peskov.

“Both the CSTO and, most likely, the EurAsEC, and the informal CIS leaders’ summit,” Peskov told reporters in response to a clarifying question about which events are scheduled for December 6 in St. Petersburg.

Earlier, Russia invited Uzbekistan to join the supervisory board of the CSTO Parliamentary Assembly.

The Collective Security Treaty Organization was established in May 1992 after the signing of the relevant document in Tashkent. Currently, the organization includes Armenia, Belarus, Kazakhstan, Kyrgyzstan, Russia and Tajikistan. Uzbekistan suspended membership in the CSTO twice - from 1999 to 2006, and then from summer 2012 to the present.

The main goal of the organization is the military support of any of the member states in the event of aggression against it.
