The CSTO member States are: the Republic of Armenia, the Republic of Belarus, the Republic of Kazakhstan, the Kyrgyz Republic, the Russian Federation, and the Republic of Tajikistan.
At the current stage in the development of international relations, there is an increasing interdependence on the part of the entities involved, and the political weight of regional and subregional associations of States is growing. This process is particularly evident in such key areas as cooperation in the field of military and political security, and adequate collective efforts to counteract new challenges and threats, which include, first of all, international terrorism and extremism, illegal drug and arms trafficking, and organized transnational crime. In all these areas, there is a close intertwining of the efforts undertaken by the United Nations and intergovernmental associations, including the Collective Security Treaty Organization.
Within the structure of CSTO, which has established contacts with the Counter-Terrorism Committee of the United Nations Security Council, the Anti-Terrorism Centre of the Commonwealth of Independent States as well as corresponding structures of the Organization for Security and Cooperation in Europe, the Collective Rapid-Deployment Forces, set up in 2001, are functioning, and a standing mechanism is being established in the field of peace-making with the possibility of its participation in peace-making operations, including those under the aegis of the United Nations.
The purposes of CSTO, which became a regional international organization when its charter entered into force on 18 September 2003 and which was registered in the United Nations Secretariat on 16 December 2003, are the strengthening of peace and international and regional security and stability, and the protection on a collective basis of the independence, territorial integrity and sovereignty of the member States. In achieving these purposes, member States attach priority to political means in complete conformity with the Charter of the United Nations and the generally recognized norms of international law. CSTO has at its disposal all the necessary mechanisms for actively participating in the efforts of the world community to strengthen peace and international security.
The Collective Security Treaty Organization participates in the sessions and work of the United Nations General Assembly as an observer.
