Commonwealth
The Commonwealth of Independent States (CIS) is a loose alliance or confederation consisting of 10 of the 15 former Soviet Republics, the exceptions being Turkmenistan (a CIS associate member), Lithuania, Latvia, Estonia, Ukraine, and Georgia. Georgia left the CIS in August 2008 after a clash with Russia over South Ossetia. Its creation signalled the dissolution of the Soviet Union, its purpose being to "allow a civilised divorce" between the Soviet Republics. The CIS has developed as a forum by which the member-states can co-operate in economics, defence, and foreign policy.
