尖閣諸島問題
The Senkaku Islands dispute, or Diaoyu Islands dispute, is a territorial dispute over a group of uninhabited islands known as the Senkaku Islands in Japan, the Diaoyu Islands in the People's Republic of China (PRC), and Tiaoyutai Islands in the Republic of China (ROC or Taiwan). Aside from a 1945 to 1972 period of administration by the United States as part of the Ryukyu Islands, the archipelago has been controlled by Japan since 1895. According to Lee Seokwoo, the People's Republic of China (PRC) started taking up the question of sovereignty over the islands in the latter half of 1970 when evidence relating to the existence of oil reserves surfaced. Taiwan (the Republic of China; ROC) also claims the islands. The territory is close to key shipping lanes and rich fishing grounds, and there may be oil reserves in the area.
