In addition to the United States, Britain and the Soviet Union, China and many other countries in the world have also made great contributions to the establishment of the international anti-fascist alliance. China not only opened up the first large-scale anti-fascist battlefield in the world, but also dealt a powerful blow to the arrogance of Japanese fascist aggression, supported the anti-fascist struggle of people in other countries with practical actions, and actively advocated the establishment of an international anti-fascist alliance. As early as the second day after the German invasion of the Soviet Union, the China Producers' Party focused on the overall strategic situation of the world and issued the instruction of "Anti-Fascist International United Front", clearly pointing out that "at present, the task of the world producers is to mobilize people from all countries to organize an international United front against fascism". After the outbreak of the Pacific War, the two parties in China immediately responded, advocating the establishment of a United front for all anti-Japanese people in the Pacific region, establishing a formal alliance, and insisting on War of Resistance against Japanese Aggression's complete victory. 19411On February 9th, the leaders of China also called the heads of the United States, Britain and the Soviet Union and suggested that a joint military conference be held in Chongqing to coordinate the actions of all countries. Undoubtedly, these measures have effectively promoted the establishment of the international anti-fascist alliance. Therefore, China, together with the United States, Britain and the Soviet Union, took the lead in signing the United Nations Declaration, which not only reflected China's important position and role in the Second World War, but also affirmed China's contribution to the establishment of the international anti-fascist alliance.
