The Sino-Japanese dispute over the Diaoyu/Senkaku Islands is not single or simple as it itself may indicate. Instead, it is a multifaceted and complicated issue. The complexity of the dispute lies not only in its multiple and interrelated foci such as its ownership, its return, and the demarcation of Sino-Japanese maritime boundary, but also in its entanglement with other problems in bilateral relations, both China and Japan’s domestic politics, and their respective broad foreign relations as well. 

Since the disagreements between China and Japan over the islands are too complex to be reduced to a single cause and both sides prefer to attach great significance to their claims to the disputed islands due to their security, economic, and political implications, the claimants find great difficulties in coping with this issue. Although the dispute has not led to direct military conflict between the parties involved, neither side can afford to relax its vigilance. The governments have been at pains to downplay the issue, keep the dispute as low-key as possible, and prevent the trouble from deteriorating bilateral relations. But they are at the mercy of domestic and international political factors beyond their immediate control.”
