The Japanese government＇s claim of＂nationalization＂ of Diaoyu Island is worsening the tensions in China and Japan＇s economic and trade cooperation, the exchange of personnel and politics and military fields. Approaching the issue from the perspective of the international system evolution can provide us a new way of solving the problem. Because of the unsettlement of the new intemational system, shelving disputes is the most feasible approach.展开更多

Given the fact that these islets are tiny, uninhabited and remote, as well as that no rival claims to them had existed for a fairly long period of time, the actual sovereign functions exercised by China regarding these islands before 1895 established the original title of China to the Diaoyu Islands. Thus Japan could not acquire the title to these islets by occupation.展开更多
