Three Worlds Theory
In the later decades the most significant use of the phrase has been in the Maoist critique of the Soviet Union. Mao Zedong argued that the Soviet Union had itself become an imperialist power while maintaining a socialist façade. Albanian leader and Chinese ally Enver Hoxha agreed with Mao in this analysis, before later using the expression to also condemn Mao's Three Worlds Theory amid the Sino-Albanian split.
