It is not an affiliated island of the province, but an affiliated island of the East China Sea of China.

Diaoyu Island, also known as Diaoyutai Island, Fishing Island and Fishing Mountain, is the main island of Diaoyu Island and its affiliated islands in the East China Sea of China, and has been the inherent territory of China since ancient times. It is located at 25 44.6' north latitude and123 28.4' east longitude, about 358km away from Wenzhou, Zhejiang, 385km away from Fuzhou, Fujian, 0/90km away from Keelung, Taiwan Province, and the surrounding sea area is about174,000 square kilometers.

China patrol law enforcement vessels insist on law enforcement in the Diaoyu Islands waters, while fishery law enforcement vessels conduct regular law enforcement cruises and fishing protection in the Diaoyu Islands waters to maintain the normal fishery production order in the waters. China also manages the Diaoyu Islands and its adjacent waters by issuing weather and ocean observations and forecasts.

Strategic value

Diaoyu Island is an uninhabited island, located in the Ryukyu Trough between China and Ryukyu. In terms of continental shelf division, China and Japan are opposite continental shelves, separated by Okinawa Trough, but Diaoyu Island is located on the west side of Okinawa Trough. Once Japan has administrative jurisdiction over the Diaoyu Islands, it will not only occupy the Diaoyu Islands, but set its territory on the continental shelf of China, and China and Japan will become the continental shelf of confrontation.

Luo Yuan, Deputy Secretary-General and Major General of Chinese Academy of Military Sciences, pointed out that according to the International Convention on the Law of the Sea, if Diaoyu Island is illegally occupied by Japan, China and Japan will have to divide the continental shelf according to the median principle, and China will not only lose a lot of maritime jurisdiction and seabed resources, but also push the strategic blockade of the United States and Japan to China from the first island chain to the west of the median line.

From the perspective of military geography, Diaoyu Island and its affiliated islands have very important but little-known military value. In the ocean direction of Chinese mainland territory, a natural barrier is formed at the outer edge of the mainland. In the middle of this series of islands, just in front of the East China Sea of China, are the Ryukyu Islands and Taiwan Province Island, which together with Kyushu Island separate the East China Sea of China from the Pacific Ocean.
