Who can give me the general process of the development of the Diaoyu Islands issue? It is best to have an overall description of this incident. Thank you! ^O^

Diaoyu Island is the main island of the Diaoyu Islands and an inherent territory of China. It is located in the East China Sea, about 356 kilometers away from Wenzhou City, about 385 kilometers away from Fuzhou City, and about 190 kilometers away from Keelung City, covering an area of ??4.3838 square kilometers. , the surrounding sea area is about 170,000 square kilometers. In 1972, the United States "handed over" its "administrative jurisdiction" together with Ryukyu to Japan. Historically, Ryukyu did not belong to Japan. This resulted in the Sino-Japanese Diaoyu Islands dispute. Since the 1970s, Chinese non-governmental organizations have repeatedly carried out "Diaoyu Islands Protection Movement" to declare sovereignty. Since September 10, 2012, relevant Chinese departments have carried out regular surveillance and monitoring of the Diaoyu Islands and its affiliated islands; on September 11, CCTV broadcast the weather forecast for the Diaoyu Islands for the first time. On September 17, 2012, CCTV reported: Chinese scholars discovered that the Japanese government knew that the Diaoyu Islands belonged to China in 1895.

The earliest document about the Diaoyu Islands in China comes from "Shunfeng Xiangshuo" in the first year of Yongle in the Ming Dynasty (1403), which calls the island "Diaoyu Island" [2]. Later documents and official maps also used the name "Diaoyu Island", such as the "Envoy to Liuqiu" written by Chen Kan, the eleventh envoy in the 13th year of Jiajing's reign in the Ming Dynasty (1534) [3], and the 41st year of Jiajing's reign in the Ming Dynasty. (1562) "Caohai Tubian" compiled by Zhejiang Admiral Hu Zongxian, and "Kunyu Complete Map" commissioned by Emperor Qianlong in the 32nd year of the Qing Dynasty (1767) ("Kunyu Complete Map" is pronounced in Hokkien, Called "Hao-yu-su" [Hao-yu-su], that is, "Diaoyu Island"). Taiwan still uses the name "Diaoyutai" to this day. In modern times, the mainland calls the island "Diaoyu Island", and sometimes also uses the name "Diaoyutai".

On the morning of September 10, 2012, an island purchase contract was signed with the so-called "owners" of the Diaoyu Islands - the Kurihara family, realizing the "nationalization" of the Diaoyu Islands. The Japanese government officially decided to purchase the Diaoyu Islands with the intention of "nationalizing" them. The Japanese government held a cabinet meeting on the morning of September 11, 2012, and decided to allocate 2.05 billion yen (approximately RMB 166 million) from the reserve funds of the 2012 budget to "purchase" the Diaoyu Islands and three affiliated islands. "Nationalize" it.
