Abstract: The Diaoyu Island question is the historical question between China and Japan's territorial sovereignty ownership. Diaoyu Island is the Chinese territory since the ancient times. The Japanese real occupation to Diaoyu Island, as well as the Japanese side of the strong standpoint which holds in the Diaoyu Island question, causes the Diaoyu Island question more complicated day by day, and has become one of the most sensitive questions in the Sino-Japanese relations. So it not only relates to the development of Sino-Japanese relations, but moreover involves the Asian and Pacific area strategy of the general pattern development in the situation. China and Japan must embark the Diaoyu Island question from the 21st century's relations between the two countries' development general situation, properly process the difference properly, and peacefully settle the disputes.
