The CPY/LCYugoslavia, the CPChina, All-Union Communist Party(B)/CPSU in the international communist movement (1945-1957)

Introduction. The Communist Party of China and the Communist Party of Yugoslavia (since 1952, the League of Communists of Yugoslavia) are parties that came to power in the PRC and the FPRY respectively as a result of World War II, national liberation and social revolutions (1945-1949 and 1945, respectively. The history of the relationship between these two actors of the international communist movement developed in a very complex and contradictory way. This article examines the dynamics of inter-state and inter-party relations between the PRC and Yugoslavia. The scale and nature of interaction between these two parties and states was in close interrelation with their relations with the All-Union Communist Party of Bolsheviks (since 1952 - the CPSU) and the USSR. 
Materials and methods. The article analyses official party documents of the CPC, CPSU/UKY and CPSU, transcripts of meetings of leaders of these parties and states, minutes of meetings and reports of the Cominfom, party newspapers and magazines, personal notes of party leaders, as well as literature on the problems of relations between the CPC/ PRC, UKY/Yugoslavia and the CPSU/USSR. The authors used the following methods in their research: narrative, reconstruction, historical-genetic, comparative-historical and historicaltypological methods. 
Analysis. The International Communist Movement (hereinafter - ICM) unites communist parties, organizations and movements all over the world, striving to build a society based on socialist principles and, ultimately, to transition to communism. The communist movement was formed on the basis of the teachings of Karl Marx, Friedrich Engels and Vladimir Lenin, and later developed with the influence of leaders and, over time, becoming theorists such as Joseph Stalin, Mao Zedong and Josip Broz Tito. After the October Revolution, in 1919 the Comintern, an organization uniting the communist parties of various countries, was established in Russia and existed until 1943.
It was succeeded by Cominform (Information Bureau of Communist and Workers' Parties), which operated from 1943- 1956 and united the most influential communist parties in Europe. CominformincludedtheAll-UnionCommunistPartyofBolsheviks, as well as the Communist Parties of Bulgaria, Hungary, Poland, Romania, Czechoslovakia, Yugoslavia, France and Italy. The central printed organ of the organisation was the newspaper ‘For lasting peace, for people's democracy!’, initially published in Belgrade, and after the beginning of the conflict between the USSR and Yugoslavia in 1948, in Bucharest. One of the main tasks of the Cominform was to combat ideological deviations within the communist movement. The decision to dissolve Cominform was taken on 17 April 1956. The official reason was the desire of the USSR and its allies to strengthen international communist cooperation on a bilateral basis rather than through a centralized structure. However, the real reason was the gradual decentralization of the ICD, which began after the 20th Congress of the CPSU in 1956. After the abolition of the Cominform, the ICD functioned at the level of meetings of communist and workers' parties - world, pan-European and socialist countries. 
Results. Based on the results of the study, the authors concluded that in 1945-1957 the relations between the ruling communist parties underwent a complex evolution.
