China and Japan coast guards have been conducting joint patrols in the disputed waters of the East China Sea. The patrols are aimed at asserting each country's claims over the region, which has long been a source of tension between the two nations.
The East China Sea is home to a group of uninhabited islands known as the Senkaku Islands in Japan and the Diaoyu Islands in China. Both countries claim sovereignty over the islands, leading to frequent disputes and confrontations in the area.
