Context: Faced with growing separatism, Gorbachev sought to restructure the Soviet Union into a less centralized state. On August 20, 1991, the Russian SFSR was scheduled to sign a New Union Treaty that would have converted the Soviet Union into a federation of independent republics with a common president, foreign policy and military. It was strongly supported by the Central Asian republics, which needed the economic advantages of a common market to prosper. However, it would have meant some degree of continued Communist Party control over economic and social life.
