中美英反法西斯盟国在《开罗宣言》中对处置日本海外领地进行了原则规定，盟国的立场和态度充分体现在“三个所有”的规定上。处置日本海外领土中，琉球群岛的地位和定性非常关键，直接关系到战后处置日本本土问题。西方国家对琉球群岛的立场是清晰的，即琉球群岛不是日本固有领土。《波茨坦公告》是《开罗宣言》处置日本的原则规定的逻辑发展，其对战后日本领土主权作出明确规定，即战后日本领土主权仅限于其本土四岛及盟国决定的临近小岛礁。将日本所有武装力量及附属民事机构从北纬30°线以南地区驱逐出去是《开罗宣言》、《波茨坦公告》的法律文件的实施要求，也是日本战败的必然，由此北纬30°线成为战后中日海上岛屿领土的分界线。

In Cairo Communiquéthe three great Allies declared that Japan should be stripped of all the islands in the Pacific which it seized or occupied since the beginning of World War I in 1914,and that all the territories Japan has stolen from China,such as Manchuria,Formosa,and the Pescadores,should be restored to the Republic of China,Japan would also be expelled from all other territories which she has taken by violence and greed.The western countries are familiar with the history of Liuchiu islands and know Liuchiu islands are not Japan's inherent territories.Japan's sovereignty in the post World War Ⅱ is limited to four native islands and its adjacent minor off-lying islands north of 30 degrees north latitude line Potsdam Declaration stipulates that all Japanese armed forces personnel and their civilian auxiliaries shall be evacua-ted from all land and water areas south of 30 degrees north latitude.It is not only requirements but also im-plementation results of Cairo Communique and Potsdam Proclamation.As a result,30 degrees north latitude line became the dividing line of islands territory between China and Japan.
