I think you mean the People's Republic of China. And yes, the USSR could reform. Avoid the 1991 coup, and let Gorbachev carry out the rest of his reforms. Russia becomes a (mostly) democratic nation, and a member of the Union of Sovereign States. It would be extremely hard, if not down right impossible to keep the Baltics or the Caucasus, though. Without the breakup of the USSR, no Chechen War, for one. The Mujahideen might also attack Russia, the larger, closer and more recent enemy, rather than the USA, thereby avoiding 9/11, at least in New York.
