Diaoyu Island is an uninhabited island, but it is located in the Okinawa Trough between China and Japan. 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 owns the Diaoyu Islands, it will not only occupy the islands on the Diaoyu Islands, but let its territory step on the continental shelf of China, and China and Japan will become the continental shelf of confrontation. Major General Luo Yuan, Deputy Secretary-General of the Chinese Academy of Military Sciences, pointed out that according to the international convention on the law of the sea, if Diaoyu Island is occupied by Japan, China and Japan will have to divide the continental shelf according to the median principle. China will not only lose a lot of maritime jurisdiction and seabed resources, but also push the strategic blockade line of the United States and Japan against China from the first island chain to the west of the median line. In recent years, Japan has invested a lot of resources in the investigation of the East China Sea. According to Chikage Ogi, former Minister of Land, Infrastructure, Transport and Tourism of Japan, these sea areas contain minerals and fishery resources such as manganese, cobalt, nickel and natural gas that Japan can consume for 320 years. Obtaining these sea areas will turn Japan from a small resource country into a resource power in East Asia. The oil and gas reserves in the East China Sea are about 7.7 billion tons, which is enough for Japan to use for nearly a hundred years. Diaoyutai Islands and its adjacent waters are not only rich in oil resources, but also rich in other aspects.

The great economic value of the topographic map of Diaoyu Island. This is a fishing ground in the East China Sea. The Kuroshio in the Pacific Ocean flows through here, bringing a lot of fish, so fishermen from Zhejiang, Fujian and Taiwan Province provinces often go fishing in this area. There is a "Snake Island Strait" with a width of 1000 meters between Diaoyu Island and the southeast, north and south islands, which is calm and has become a natural shelter for fishermen. In this strait harbor, there are also abundant flying fish, and fishermen in Keelung and Suao of Taiwan Province Province often rely on this fishing area for survival. Diaoyu Island is the largest of the eight small islands, covering an area of about 4.3 square kilometers. Diaoyu Island and its affiliated islands have exposed bedrock with spikes, thin soil foundation and lack of fresh water. Camellia, palm and purslane can be seen everywhere, and cactus can be seen everywhere. Obviously, in order to adapt to the natural environment of strong winds at sea, these plants grow short and stout, and many of them are precious medicinal materials. There is a kind of seaweed called Hibiscus, which grows in the crevices of coastal rocks and is a good medicine to prevent rheumatism and hypertension. Many ancestors of herb gatherers along the coast of China collected herbs in Diaoyutai Islands. 195 1 The San Francisco Peace Treaty entrusted Diaoyu Island to the United States1951On September 8, Japan and the United States signed a one-sided San Francisco Peace Treaty (officially known as the Japan-US Security Treaty, also known as the Japan-US Security Treaty) and handed over Diaoyu Island to the United States together with Okinawa, Japan. In this regard, Premier Zhou Enlai and Foreign Minister solemnly declared on behalf of the Japanese government that the San Francisco Peace Treaty is a separate peace treaty without the participation of the people of China, not only not a comprehensive peace treaty, but also not a real peace treaty. In the late 1960s, a United Nations committee announced that there might be a lot of oil and gas near the island.

Immediately after the Diaoyu Islands, Japan took unilateral action. First, several oil companies went to explore, and then the patrol boat left. Without authorization, the original signs indicating that these islands belong to China were destroyed and replaced with boundary markers indicating that these islands belong to Okinawa Prefecture, Japan, and eight islands in the Diaoyu Islands were given Japan's own names.

Diaoyu Island is sweet potato-shaped, about 3.5 kilometers long from east to west, about 1.5 kilometers wide from north to south, and covers an area of about 4.3 square kilometers. The terrain is high in the north and steep in the south, and the central mountains cross the east and west; The highest peak is 362 meters above sea level, located in the middle; Other peaks are 320 meters, 258 meters and 242 meters above sea level, and there are four major rivers. Located on the continental shelf of the East China Sea. The Ryukyu Islands in Okinawa, Japan are volcanic islands outside the continental shelf, and the Ryukyu Islands are located on the continental shelf of the East China Sea.
