context_page_description: The Collective Security Treaty Organization is an intergovernmental military alliance that was signed on 15 May 1992. In 1992, six post-Soviet states belonging to the Commonwealth of Independent States—Russia, Armenia, Kazakhstan, Kyrgyzstan, Tajikistan, and Uzbekistan—signed the Collective Security Treaty. Three other post-Soviet states—Azerbaijan, Belarus, and Georgia—signed the next year and the treaty took effect in 1994. Five years later, six of the nine—all but Azerbaijan, Georgia, and Uzbekistan—agreed to renew the treaty for five more years, and in 2002 those six agreed to create the Collective Security Treaty Organization as a military alliance.
  Nikolai Bordyuzha was appointed secretary general of the new organization. On 23 June 2006, Uzbekistan became a full participant in the CSTO; and its membership was ratified by the Uzbek parliament on 28 March 2008. It suspended its membership in 2012. The CSTO is an observer organization at the United Nations General Assembly.
  The CSTO charter reaffirmed the desire of all participating states to abstain from the use or threat of force.

  On 6 October 2007, CSTO members agreed to a major expansion of the organization that would create a CSTO peacekeeping force that could deploy under a U.N. mandate or without one in its member states. The expansion would also allow all members to purchase Russian weapons at the same price as Russia.
  On 29 August 2008, Russia announced it would seek CSTO recognition of the independence of Abkhazia and South Ossetia. Three days earlier, on 26 August, Russia recognized the independence of Georgia's breakaway regions of Abkhazia and South Ossetia.
  On 5 September 2008, Armenia assumed the rotating CSTO presidency during a CSTO meeting in Moscow, Russia.
  In 2009, Belarus boycotted the CSTO summit due to their Milk War with Russia.
  On 10 December 2010, the member states approved a declaration establishing a CSTO peacekeeping force and a declaration of the CSTO member states, in addition to signing a package of joint documents.
  Since 21 December 2011, the Treaty parties can veto the establishment of new foreign military bases in the member states of the Collective Security Treaty Organization (CSTO). Additionally, Kazakhstan took over the rotating presidency of the CSTO from Belarus.
  In August 2014, 3,000 soldiers from the members of Armenia, Belarus, Kazakhstan, Kyrgyzstan, Russia and Tajikistan participated in psychological and cyber warfare exercises in Kazakhstan under war games managed by CSTO.
  On March 19, 2015, the CSTO Secretary General Nikolai Bordyuzha offered to send a peacekeeping mission to Donbass, Ukraine. "The CSTO has a peacekeeping capacity. Our peacekeepers continuously undergo corresponding training. If such a decision is taken by the United Nations, we stand ready to provide peacekeeping units.”
