Collective Security Treaty Organization

The Collective Security Treaty (CST) was signed on May 15, 1992 in Tashkent by the Heads of six countries: Armenia, Kazakhstan, Kyrgyzstan, Russia, Tajikistan and Uzbekistan. Subsequently, Azerbaijan, Georgia and Belarus joined it. The treaty came into force on April 20, 1994. In April 1999, the Protocol on prolongation of the Collective Security Treaty was signed by six of them (except for Azerbaijan, Georgia and Uzbekistan).

It was decided to transform the CST into a full-fledged international organization – the Collective Security Treaty Organization (CSTO) at the Moscow session of the Collective Security Treaty on May 14, 2002. On October 7, 2002 the Charter of the Collective Security Treaty Organization and the Agreement on legal status of the CSTO were signed in Kishinev and came into force on September 18, 2003.

On December 2, 2004 the UN General Assembly adopted a resolution granting the Collective Security Treaty Organization (CSTO) an observer status in the UN General Assembly.

The statutory bodies of the Organization are the following: the Collective Security Council (CSC), the Council of Foreign Ministers (COM), the Council of Ministers of Defense (CIO), the Committee of Secretaries of Security Council (CSSC).

The fundamental aim of the Organization is to continue and strengthen close and comprehensive relations in the foreign policy, military, military-technical spheres, coordination and joint efforts in combating international terrorism and other security threats.

The key objectives of the CSTO iclude the provision of national and collective security, intensive military-political cooperation and integration, foreign policy coordination on international and regional security issues, the establishment of multilateral cooperation mechanisms, including a military component, the development of cooperation in the counteraction to modern challenges and security threats, such as international terrorism, drug trafficking, illegal migration, transnational organized crime, information and cyber security, military-technical cooperation.

Belarus actively cooperates with the CSTO, stands for a strong and effective Organization and its' integration into the Eurasian security architecture.

During its' chairmanship in the CSTO in 2017, the main priorities of Belarus were to strengthen the CSTO influence on the international arena, increase the operational readiness of the CSTO collective forces, expand the CSTO economic security agenda, and implement additional measures to counter international terrorism and drug trafficking, ensure stable migration flows in the CSTO collective regions.

During the CSTO CSC session in November 2018 in Astana, it was decided to institutionalize the Organization’s observer and partner status based on the Belarus’ initiative to establish a partnership institution initiated during Belarus’ CSTO chairmanship in 2011-2017. This decision lays the foundation for the development and expansion of the CSTO interaction with other international organizations and third countries.

On November 28, 2019 a session of the Collective Security Council was held in Bishkek. At the session a number of important documents was signed in various areas of the Organization’s activity, including in the field of strengthening military and military-technical cooperation, fight against terrorism and cybercrime.

As part of Russia's chairmanship of the CSTO, on December 2, 2020, a session of the Collective Security Council was held via videoconference, which resulted in the adoption of a Declaration and a Statement on the Formation of a Fair and Sustainable World Order. The heads of state approved the Plan for the Development of Military Cooperation of the CSTO Member States for 2021-2025 and a new Anti-Drug Strategy for 2021-2025.
