日本发动侵略中国东北的“九·一八”事变，打破了帝国主义在远东和太平洋地区的均势，但是制定和维护远东“国际秩序”的主要国家——英国、美国、法国分别采取了所谓的“不干涉主义”、“不承认主义”和“好人主义”的政策，而与中国东北接壤的社会主义国家——苏联实行了“两面主义”的政策。欧美大国对“九·一八”事变的政策都是为了维护本国利益，起到了纵容日本侵略的作用，对中国人民抗日斗争是一个重大打击。 Japan launched the “September 18th” incident that invaded northeast China and broke the balance of imperialism in the Far East and the Pacific. However, the major countries that formulated and maintained the “international order” in the Far East - Britain, the United States and France respectively adopted the so-called “Non-interventionism,” “non-recognitionism,” and “goodmanism.” The socialist policy of the Soviet Union, which is bordering on the northeast of China, has implemented a “two-sided” policy. The policies adopted by the major powers in Europe and the United States on the September 18 Incident were aimed at safeguarding their own interests and playing a conniving role in Japan’s aggression and were a major blow to the Chinese people’s anti-Japanese struggle.
