库页岛自古以来就是中国领土不可分割的一部分,但从19世纪起,鉴于库页岛重要战略地位和丰富自然资源,逐渐成为日俄争夺的对象。日俄对库页岛的争夺可以分为三个阶段,而这三个阶段的争夺都是伴随俄国东方政策与日本大陆政策矛盾冲突,以及西方帝国主义在东北亚的角逐而展开的。 Since ancient times, Sakhalin Island has been an inalienable part of Chinese territory. However, since the 19th century, given the important strategic position of Sakhalin Island and the abundant natural resources, Sakhalin Island has gradually become the object of the rivalry between Japan and Russia. The battle between Japan and Russia on Sakhalin Island can be divided into three stages. The competitions in these three stages are accompanied by the contradictions and conflicts between the Russian Oriental Policy and Japan’s mainland policy and the Western imperialist rivalry in Northeast Asia.
