Collective Security Treaty Organization (CSTO)


Moscow, Russian Federation

Web site

Short description

The CSTO is a military alliance that promotes the collective defence of any member that comes under external aggression. It also strives for its members to coordinate their efforts against terrorist threats, illicit drug trafficking, and transnational crime.


CSTO members cover the organization’s Secretariat and operational costs. The Russian Federation’s contribution accounts for about 50 per cent of the CSTO’s budget. The remaining costs are evenly distributed among the other member states.

The CSTO, created in 2002, has its origins in the 1992 Collective Security Treaty. Armenia, Kazakhstan, Kyrgyzstan, the Russian Federation, Tajikistan, and Uzbekistan were the first signatories of the Treaty. Azerbaijan, Belarus, and Georgia subsequently signed the treaty in 1993. Azerbaijan, Georgia, and Uzbekistan withdrew in 1999, but Uzbekistan rejoined in 2006. (Thus, Uzbekistan is treated as a founding member, even though it was not a member when the CSTO was formally established. Yet Belarus is not treated as a founding member, even though it was an original signatory to the CSTO Charter.)

PoA-related activities

The CSTO identifies countering ‘challenges and threats to security’, including terrorism, violent forms of extremism, drug trafficking, and organized crime, as one of its main area of activity. Coordination of efforts in the field of countering the illicit circulation of weapons among others is a charter-based mandate of the CSTO (Article 8 of the 2002 CSTO Charter). To this end, the CSTO has developed coordination mechanisms and information exchange procedures, and has supported law enforcement training for its members. (The Russian Federation takes a lead role in training CSTO members in the field of countering narcotics.) CSTO Operation Kanal, a multi-year anti-drug campaign begun in 2003, has netted many illicit weapons. The initiative engages countries beyond the CSTO’s membership and takes place in the territory of CSTO members and some states that ‘observe’ the annual exercise. (There are 25 such states.) Between 2003 and 2011, 17 stages of the operation were implemented with a total of 14,865 firearms and 435,352 munitions removed from illegal circulation.
