Collective Security Treaty Organization

  • CSTO 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
  • This is also referred to as the “Tashkent Pact” or “Tashkent 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 CSTO as a military alliance.
