On December 8, the leaders of Russia, Ukraine, and Belarus secretly met in Belavezhskaya Pushcha, in western Belarus, and signed the Belavezha Accords, which proclaimed the Soviet Union had ceased to exist and announced formation of the Commonwealth of Independent States (CIS) as a looser association to take its place. They also invited other republics to join the CIS. Gorbachev called it an unconstitutional coup. However, by this time there was no longer any reasonable doubt that, as the preamble of the Accords put it, "the USSR, as a subject of international law and a geopolitical reality, is ceasing its existence."

Answer this question, if possible (if impossible, reply "unanswerable"): What was formed to replace the Soviet Union?
the Commonwealth of Independent States
