China Federation for Defending the Diaoyu Islands

China Federation for Defending the Diaoyu Islands is a non-governmental organization which maintains that the Senkaku/Diaoyu/Tiaoyutai Islands are a part of Chinese territory in the Senkaku Islands dispute. The territorial rights to the islands are disputed between the China, the Taiwan, and Japan, which currently has control over the islands.

In the early morning of March 24, 2004, seven activists from the group landed on the islands, planning to stay for several days. That afternoon, they were detained by the Japanese coast guard. The incident gave the territorial dispute renewed media attention and worsened Sino-Japanese relations.
