Armenia–CSTO relations

Armenia

Collective Security Treaty Organization

Bilateral relations between Armenia and the Collective Security Treaty Organization (CSTO) were formalized when Armenia became a full member of the CSTO in 1994. Since February 2024, Armenia has frozen their CSTO membership, and has taken steps towards formally withdrawing. Following the suspension of its CSTO membership, the Armenian government decided to deepen and strengthen its relations with the European Union and the United States.
