 All presidents of post-Soviet Russia were members of the Communist Party of the Soviet Union (Boris Yeltsin before 1990, Vladimir Putin and Dmitry Medvedev before 1991).Azerbaijan is an authoritarian dominant-party state and North Korea is a totalitarian one-party state led by the heirs of their Eastern Bloc leaders, yet both have officially eliminated mentions of communism from their constitutions.In addition, the term "New Eastern Bloc" recently applies to countries allied with China and Russia such as Venezuela, Syria, Iran, Serbia and many other countries.
