Diaoyu Island, the full name of Diaoyutai Islands, is called Senkaku Islands by the Japanese. Diaoyu Island consists of Diaoyu Island, Huangwei Island, chiwei yu, South Island, North Island, Danan Island, Dabei Island and Feisai Island, with a total area of about 7 square kilometers.
Geographical location: east longitude 123- 124 34', north latitude 25 40'-26'
Relative location: due east of Fujian, northeast of Taiwan Province. It is 0/02 nautical mile from Keelung/KLOC-and 230 nautical miles from Naha.
Geological features: Its sea area is a Neogene sedimentary basin rich in oil. According to 1982, it is estimated to be 73.7-157.4 billion barrels.
Geographical Features: Located on the continental shelf, it is attached to Taiwan Province Island and separated from Ryukyu Islands by a trench. This archipelago consists of seven small islands.
/kloc-Before the Sino-Japanese War of 1894-1895 broke out at the end of 0/9, Japan did not raise any objection to China's sovereignty over Diaoyu Islands. 1884, Koga, a resident of Naha, Japan, landed on Diaoyu Island for the first time to collect feathers and catch the surrounding seafood. His subsequent petition to develop the Diaoyu Islands was also rejected by the Governor of Okinawa Prefecture. After 1885, the governor of Okinawa wrote to the Japanese government many times, demanding that Diaoyu Island, Huangwei Island and chiwei yu be placed under his jurisdiction. Japanese officials have given consideration to the sovereignty claims of the Qing government in China on these islands, and made no reply. However, after 1894- 1895 Sino-Japanese War of 1895, Japan seized Taiwan Province Province and its affiliated islands by forcing the Qing government to sign the treaty of shimonoseki. After the Japanese defeat in World War II, Taiwan Province Province was returned to China, but Diaoyu Island, an affiliated island of Taiwan Province Province, was privately entrusted to the United States.
In the late 1960s, after a United Nations committee announced that there might be a large amount of oil and gas near the island, Japan immediately took unilateral action. First, several oil companies went to explore, and then the patrol boat was robbed. Without authorization, the signs originally indicating that these islands belong to China were destroyed and replaced with boundary markers indicating that these islands belong to Okinawa Prefecture, Japan, and the eight islands on the Diaoyu Islands were given Japanese names.
197 1 year, when the United States and Japan signed the agreement to return Okinawa, they gave it to each other privately, and included the Diaoyu Islands and other islands in the scope of return. This transaction was strongly protested by the government of China. In the negotiations on the resumption of diplomatic relations between China and Japan in 1972, the two sides, proceeding from the overall situation of Sino-Japanese friendship, agreed to temporarily shelve the issue of the ownership of the Diaoyu Islands until the future conditions are ripe. However, when China and Japan negotiated and signed the Sino-Japanese Treaty of Peace and Friendship in 1978, some Japanese parliamentarians who were hostile to China asked China to recognize Japan's sovereignty over the Diaoyu Islands. At the request of the Rightists, the Japanese government dispatched patrol boats and planes to monitor my fishermen working on the Diaoyu Islands. In May of the following year, the Japanese government used patrol boats to transport personnel and equipment to the Diaoyu Islands, built a heliport there, and sent investigation teams and investigation boats there.
Since the 1990s, with the changes in the world situation and the balance of power among countries, Japan has once again extended its hand to the Diaoyu Islands. 1990 10 with the permission of the government, some Japanese right-wingers built a lighthouse on an island on the Diaoyu Islands. Taiwan Province Province also dispatched 12 boat and two helicopters to prevent Japanese fishing boats from approaching Diaoyu Island. 1July, 1996 14, Japanese right-wingers set up a lighthouse on the north island of Diaoyu Island in an attempt to put the lighthouse on the chart and let the international community recognize Diaoyu Island as Japanese territory. On August 18, Japanese right-wingers erected a wooden sign painted with the words "Sun Flag" on the Diaoyu Islands to commemorate the victims. It is worth noting that these activities carried out by Japanese right-wingers on the Diaoyu Islands have been connived and supported by the Japanese government, and government officials have cooperated with them, saying that the Diaoyu Islands are Japanese territory and demanding that the Japan Coast Guard be prepared to use force to eliminate "interference" at any time.
Why are these seven uninhabited islands coveted by the Japanese government? The problem is oil. According to the exploration results of the United Nations Economic Commission for Asia and the Far East, there may be a lot of oil in the vast continental shelf near Diaoyutai. Japan is in urgent need of oil, but it doesn't produce a drop of oil at home, and it relies entirely on imports from abroad, especially in the Middle East. So now, when I hear that there are so many oil reserves in the Liyu area of Diaoyutai near Japanese territory, I will certainly try my best to keep them for myself. Their ambition is obvious.
The Bohai Sea and the Yellow Sea in China are shallow seas on the continental shelf. The southern part of the Yellow Sea is connected with the continental shelf of the East China Sea, and there is a deep-sea trough in the eastern part of the East China Sea, called the Okinawa Trough. The length from north to south is 1000 km, the width from east to west is 150 km, and the deepest part is more than 2,700 meters. The continental slope of the East China Sea is a big slope from the continental shelf of the East China Sea to the Okinawa Trough, with a height difference of 2500 meters.
It turns out that the continental shelf of the East China Sea is also a huge basin with a depth of 4,000m m.. The edge of the basin is a series of submarine mountains. This undersea mountain range stopped the sediments brought by the rivers in Chinese mainland, and filled the 4000m-deep basin into shallow sea. On the seaward side of the mountain is the Okinawa Trough, and the seabed is cracking. Volcanic materials are ejected from deep underground, and the trough splits and expands, evolving towards the ocean.
There is enough evidence in history to prove that Diaoyu Island and other islands on the edge of the continental shelf in the East China Sea have been China's territory since ancient times. Geologically, it is an extension of the mountains in the east of Taiwan Province Province. This series of submarine mountains intercepted sediments and organic nutrients brought by rivers such as the Yangtze River and the Yellow River, and formed a 4000m thick accumulation layer (including oil and natural gas). The East China Sea, like the Okinawa Trough, is a sea basin full of seawater. Without the supply of sediments from the Chinese mainland River, the depth can reach several thousand meters. Therefore, from the natural evolution of the seabed, the continental shelf and continental slope of the East China Sea are natural extensions of the land and mountains in eastern China. It is formed by the material cultivation of land in China. Okinawa Trough is a natural dividing line, which separates the continental shelf and continental slope along the coast of China from the waters of Ryukyu Islands, and divides it into two distinct marine areas. \
Many historical facts prove that the Diaoyu Islands and other islands have always belonged to China from the Ming Dynasty to the Qing Dynasty. As long as you give one or two examples, you can clarify the facts.
1534, jiajing 13, the Ming dynasty awarded the Ryukyu kingdom, which made Chen Kan write "Ryukyu" and recorded the voyage. "On the day of 10, the south wind blew fast, and the ship flew like a fly, but it didn't go downstream. It crossed Pingjiashan, Diaoyu Island, Huangmaoyu and chiwei yu, and it was very busy. This is a three-day trip. It's too small to sail.
The "Diaoyu Island, Huangmaoyu Island and chiwei yu" mentioned in this paper, that is, the current Diaoyu Island, Huangweiyu Island, chiwei yu and Chen Kan set off from Fuzhou, passed through Diaoyu Island, Huangweiyu Island and chiwei yu as navigation marks, and then entered the Ryukyu Sea. Its sign is that they saw the ancient Ami Mountain, also known as Gumi Mountain, and now it is a Ami Mountain for a long time. This article clearly shows that the messenger Chen Kan and the Ryukyu people are in the same boat.
1722, on June 1st, Kangxi, Xu Baoguang, assistant minister of the Qing Dynasty who awarded the title of Ryukyu, also wrote the biography of Zhongshan, which also pointed out that "Ryukyu is in the sea, and the terrain of Zhejiang and Fujian is in the east and west", indicating that JiuMi Shan is the town mountain on the southwest border of Ryukyu, that is to say, the border between China and Ryukyu is between chiwei yu and JiuMi Shan.
Geographical environment as proof
"Ditch" or "Blackwater" are often mentioned in the records of Ryukyu Envoys, such as Xia Ziyang's Making Ryukyu, Wang Ji's Miscellaneous Notes on Making Ryukyu in the 34th year of Wanli in Ming Dynasty, Xu Baoguang's Biography of Ryukyu Kingdom in Zhongshan in the 22nd year of Kangxi in Qing Dynasty and Qi in the 21st year of Qianlong in Qing Dynasty.
The Ryukyu Trench is 2000 meters deep, located between the Ryukyu Islands and Diaoyu Islands. Its northeast end is connected with the Japanese Trench, and its southwest end is connected with the Mariana Islands, which geographically separates the Ryukyu Islands from the continental shelf of China, while Diaoyu Islands, Huangwei Island and chiwei yu, together with Taiwan Province Island, are all located on the continental shelf with a water depth of only 200 meters. From the continental shelf to the Ryukyu Trench, a broad ebb tide, the Kuroshio, is formed on the sea surface, just like an imperial envoy.
It is worth noting that Wang Ming called this ditch "the boundary between China and foreign countries" in Miscellaneous Notes on Ryukyu, and Huang Zhou also confirmed the "black ditch" as "the boundary with Fujian Sea". Obviously, at least in the early Qing Dynasty, China had taken the Ryukyu Trench as the dividing line between Fujian Sea and China and foreign Ryukyu, which was a matter of course.
The Japanese historical map also claims that Diaoyu Island belongs to China.
1785, the Japanese published an Overview of the Three Kingdoms written by the famous scholar Lin Xiaoping. * * There are five maps, one for North Korea, one for Ryukyu, two for Xiayi, one for Hokkaido today and one for Ogasawara Island. In the preface of the book, the author explains the purpose of cartography in this way: "The Survey of the Three Kingdoms says that it is not a teenager who dares to talk about economy, nor is it a teenager who plays with geography.
These maps are well-made, and the areas are divided by color, just like modern cartography. In the whole map of Ryukyu Kingdom, the territory of Ryukyu is orange, the Japanese part adjacent to Ryukyu is light green, and the part adjacent to China is pink, so the boundaries between countries can be clearly seen through colors. On this map, the locations of Fishing, Huangweiyu and chiwei yu are also indicated. Their colors are pink like those of Fujian and Zhejiang in China.
However, Mi Shan is as orange as Ryukyu. It is particularly important to note that the Survey of the Three Kingdoms is not an ordinary map material in Japan. The library collected in the Cabinet, the libraries of Tokyo University, Kyoto University, Waseda University, and some famous libraries. When I was studying in Japan, I went to the Ponzo Library in Nagoya many times and personally consulted the original map materials.
Among them, The Complete Map of Ryukyu Kingdom is not only quoted by many scholars, but also displayed to visitors as important historical materials every time an exhibition about the history and culture of Ryukyu and Okinawa is held. Anyone who has seen this map is obvious, and I don't know why the Japanese government turned a blind eye.
Records of missions to Ryukyu in Ming and Qing Dynasties and historical maps of Japan clearly show that Diaoyu Island, Diaoyu Island and chiwei yu belong to China. The Japanese government must respect historical facts, fulfill the provisions of the Cairo Declaration after the war, dismantle the lighthouse set up by Japanese right-wing groups on Diaoyu Island, and return the islands belonging to China to China.
It's us, China, for what!
