尖閣諸島問題
Action Committee for Defending the Diaoyu Islands () is a Hong Kong-based activist organisation that asserts Chinese sovereignty over the Diaoyu Islands, called Senkaku Islands in Japan, in the Senkaku Islands dispute. The territorial right to the islands is disputed between the People's Republic of China, the Republic of China, and Japan, who currently controls them. The group regularly sends expeditions to the islands and would make landing on them to assert Chinese sovereignty.
