Soviet leader Nikita Khrushchev made his "secret speech" On the Cult of Personality and Its Consequences to the 20th Congress of the Communist Party of the Soviet Union. The speech was a major cause of the Sino-Soviet split in which China (under Chairman Mao Zedong) and Albania (under First Secretary Enver Hoxha) condemned Khrushchev as a revisionist. In response, they formed the anti-revisionist movement, criticizing the post-Stalin leadership of the Communist Party of the Soviet Union for allegedly deviating from the path of Lenin and Stalin. Khrushchev also announced a policy of Peaceful coexistence between the Soviet-allied socialist states and the capitalist bloc in contrast to the earlier Soviet policy of world revolution.
