The disputes are all over the map. But the long-standing row between Beijing and Tokyo over the Diaoyu Islands is not simply a question of geography and national pride, but a battle for resources, economic benefits and strategic interests.
The Diaoyu Islands are a group of uninhabited islands located roughly due east of mainland China, northeast of Taiwan, west of Okinawa Island, and north of the southwestern end of the Ryukyu Islands. They are currently controlled by Japan, which calls them Senkaku Islands. Both China and Taiwan claim sovereignty over the islands.
