The 20th National Congress of the Communist Party of the Soviet Union has had huge repercussions at home and abroad. The Central Committee of the Communist Party of China sent a delegation to participate in the 20th National Congress of the Communist Party of the Soviet Union. China believes that the 20th National Congress of the Communist Party of the Soviet Union is of positive significance in breaking down Stalin's cult of personality and exposing the seriousness of his mistakes.
