In Georgia, Russian mercenaries, allegedly bolstered by Russian military support, fought alongside separatist forces from Georgia's Abkhazian Autonomous Republic, who finally defeated Georgian forces in September 1993. In October Georgia was forced to end its strong opposition to membership in the CIS by becoming a full member and signing a series of security cooperation agreements. That step prompted Russia to send military peacekeepers to support government forces, which saved Georgia's president Eduard Shevardnadze from large-scale insurrection and further fragmentation of the country. The terms of the so-called rescue included a Georgian-Russian friendship treaty calling for the establishment of Russian military bases in Georgia. In June 1994, Abkhazia and Georgia agreed to the interpositioning of Russian peacekeepers between Abkhazia and the rest of Georgia to enforce a cease-fire. In September 1995, a Russian-Georgian treaty established twenty-year Russian leases of three bases. The Russian forces continued to share cease-fire enforcement in Georgia's breakaway South Ossetian Autonomous Oblast, where they had been since 1992, because no treaty had ended that conflict. The UN military observer group deployed in Abkhazia reported cooperative relations with the Russian peacekeepers.
