The fierce propaganda campaign against the CPSU and other Marxist-Leninist parties developed in the 1960s by the Mao Tse-tung group in China confronted the international communist movement with the fact that a new front in the ideological struggle had come into being.

International relations has long been well known as a subject for research in the disciplines of history, economics, and law. However, little study of it has been done by experts in such extremely important fields of the social sciences as historical materialism and scientific communism.
