在世界反法西斯战争和中国抗日战争后期,苏联对华政策发生改变,逐渐偏离前期的国际主义和爱国主义一致的原则,在对日宣战的问题上向中国索取利益。这种政策的演变主要是苏联对华政策的出发点具有明显的二重性,随着反法西斯战争局势的好转,苏联大国主义和满足其民族主义私利的一面就暴露无遗。同时美国的纵容和国民党政府的妥协对苏联对华政策的转变也起到了推波助澜的作用。 During the world’s anti-fascist war and the post-war period of Chinese anti-Japanese war, the Soviet Union’s China policy changed and gradually deviated from the principle of unification of internationalism and patriotism. As a result, the Soviet Union claimed interest from China on the issue of declaring war on Japan. The evolution of this policy is mainly due to the obvious duality of the starting point of the Soviet Union’s China policy. With the improvement of the anti-fascist war, the Soviet Union’s big power and the satisfaction of its nationalist self-interest have been exposed. At the same time, the connivance of the United States and the compromise of the Kuomintang government have played a role in fueling the transformation of the Soviet Union’s China policy.
