The Fourth Eurasian Communist International (COMINTERN), colloquially known as the Eurasian Axis, was a political international, later turned into a treaty alliance, between the Moscow Pact (MTO), the South European Pact (SEUROP) and the Greater East Asian Co-Prosperity Sphere (GEACPS). Its foundations were laid in 1937 with the admission of the Social Strength and Unity Party (the main proponent of Social Imperialism in The State of Japan), into the Communist International (also known as the Third International). In December of 1941 this political body was used to organise the triple coalition between all three alliances, following the Pearl Harbour Attack and the subsequent signing of the Vladivostok Treaty (formalising the Soviet-Japanese alliance).
However, by late 1945, the situation had changed drastically. The Balkans were weary of Moscow's war, and the Japanese Empire had been wholly occupied by the Allies. The Fourth Eurasian Communist International was formally dissolved on the 9th of April 1946, although multiple of its institutions were kept as-is to form the Council of Mutual Economic Assistance (COMECON). By the late 1960s, the political and military purposes of the long defunct COMINTERN were replicated by the Canton Protocol Alliance Treaty (CPAT).
