CSTO

Last updated: May 29, 2026

The Collective Security Treaty Organization is a Russian-led military alliance formed in 1992 among several post-Soviet states, including Armenia. For decades it served as the formal backbone of Armenia’s security architecture, providing the legal basis for basing Russian troops in the country and for collective defense commitments. Armenia’s membership was long treated as the price of Russia’s security umbrella in a volatile region.

The relationship fractured after the 44-Day War of 2020, when Russia brokered the ceasefire but CSTO troops were never deployed to defend Armenia. The September 2023 Azerbaijani offensive against Nagorno Karabakh (Artsakh) — which resulted in the ethnic cleansing of the entire Armenian population — exposed the alliance’s unwillingness to act on Armenia’s behalf. In 2024, Armenia formally suspended its participation in CSTO activities, effectively freezing its membership without a formal withdrawal.

Groong has covered the deterioration of Armenia’s relationship with the CSTO extensively: from the initial 2020 disillusionment through repeated CSTO summits where Armenia was isolated, the failed mediation attempts, and the domestic and foreign-policy implications of Armenia’s pivot away from the Russian security orbit toward Western security partnerships with France, the EU, and India .
