Diaoyu Dao and its affiliated islands are an inalienable part of China's territory, and this is an irrefutable historical and legal fact. No matter which ancient book you look through, this fact is clear and unambiguous. From a historical point of view, Diaoyu Dao has been China's territory since ancient times.
In ancient times, Chinese fishermen often fished here, and fishermen from Taiwan, Fujian and other places also often came here
Shelter from the wind, do business, fish, and engage in fishery production activities. The Diaoyu Islands have always been under the effective jurisdiction of Chinese fishermen and are an inalienable part of China. From a historical, geographical, and legal point of view, Diaoyu Dao is China's inherent territory, over which China has indisputable sovereignty. Therefore, any attempt to change this fact is illegal and null and void.
The Chinese people are unswervingly determined to defend state sovereignty and territorial integrity, and will never allow anyone or any force to encroach upon and split the sacred territory of the motherland. The historical and legal facts about Diaoyu Dao and its affiliated islands have been clearly stated. Diaoyu Dao has been China's territory since ancient times, and this is clear from both historical documents and legal perspectives.
In the First Sino-Japanese War, Japan, as the victorious power, seized Taiwan and Penghu and other islands from the Qing Dynasty, but the Diaoyu Islands were not included in its territorial scope. On the contrary, after World War II, according to international legal documents such as the Cairo Declaration and the Potsdam Proclamation, Japan had to return to China all the territory it had plundered during the Sino-Japanese War and beyond. As a result, these islands, including the Diaoyu Islands, naturally returned to China and became an integral part of China.
Scholars such as Kiyoshi Inoue and Tadashi Murata share the same view on this point. They held that Japan's occupation of the Diaoyu Islands was an illegal act carried out under the pretext of the victory in the First Sino-Japanese War, and that it was by no means an act of upright possession. At the same time, since the Ming Dynasty, various Chinese maps and documents have marked Diaoyu Dao, Huangwei Yu, and Chiwei Yu on China's territory, which further proves that Diaoyu Dao has been Chinese territory since ancient times.
Therefore, it is an irrefutable historical and legal fact that Diaoyu Dao and its affiliated islands are an inalienable part of China. Any attempt to change this fact is illegal and null and void. The Chinese people are unswervingly determined to defend state sovereignty and territorial integrity, and will never allow anyone or any force to encroach upon and split the sacred territory of the motherland.
