Conclusion

Foreword

Diaoyu Dao and its affiliated islands are an inseparable part of the Chinese territory. Diaoyu Dao is China's inherent territory in all historical, geographical and legal terms, and China enjoys indisputable sovereignty over Diaoyu Dao.

Japan's occupation of Diaoyu Dao during the Sino-Japanese War in 1895 is illegal and invalid. After World War II, Diaoyu Dao was returned to China in accordance with such international legal documents as the Cairo Declaration and the Potsdam Proclamation. No matter what unilateral step Japan takes over Diaoyu Dao, it will not change the fact that Diaoyu Dao belongs to China. For quite some time, Japan has repeatedly stirred up troubles on the issue of Diaoyu Dao. On September 10, 2012, the Japanese government announced the "purchase" of Diaoyu Dao and its affiliated Nanxiao Dao and Beixiao Dao and the implementation of the so-called "nationalization". This is a move that grossly violates China's territorial sovereignty and seriously tramples on historical facts and international jurisprudence.

China is firmly opposed to Japan's violation of China's sovereignty over Diaoyu Dao in whatever form and has taken resolute measures to curb any such act. China's position on the issue of Diaoyu Dao is clear-cut and consistent. China's will to defend national sovereignty and territorial integrity is firm and its resolve to uphold the outcomes of the World Anti-Fascist War will not be shaken by any force.

I.

Diaoyu Dao is China's Inherent Territory

Diaoyu Dao and its affiliated islands, which consist of Diaoyu Dao, Huangwei Yu, Chiwei Yu, Nanxiao Dao, Beixiao Dao, Nan Yu, Bei Yu, Fei Yu and other islands and reefs, are located to the northeast of China's Taiwan Island, in the waters between 123o20'-124o40'E (East Longitude) and 25o40'-26o00'N (North Latitude), and are affiliated to the Taiwan Island. The total landmass of these islands is approximately 5.69 square kilometers.

Diaoyu Dao, situated in the western tip of the area, covers a landmass of about 3.91 square kilometers and is the largest island in the area. The highest peak on the island stands 362 meters above the sea level. Huangwei Yu, which is located about 27 kilometers to the northeast of Diaoyu Dao, is the second largest island in the area, with a total landmass of about 0.91 square kilometers and a highest elevation of 117 meters. Chiwei Yu, situated about 110 kilometers to the northeast of Diaoyu Dao, is the easternmost island in the area. It covers a landmass of approximately 0.065 square kilometers and stands 75 meters above the sea level at its peak.

1. Diaoyu Dao was first discovered, named and exploited by China

Ancient ancestors in China first discovered and named Diaoyu Dao through their production and fishery activities on the sea. In China's historical literatures, Diaoyu Dao is also called Diaoyu Yu or Diaoyu Tai. The earliest historical record of the names of Diaoyu Dao, Chiwei Yu and other places can be found in the book Voyage with a Tail Wind (Shun Feng Xiang Song) published in 1403 (the first year of the reign of Emperor Yongle of the Ming Dynasty). It shows that China had already discovered and named Diaoyu Dao by the 14th and 15th centuries.

In 1372 (the fifth year of the reign of Emperor Hongwu of the Ming Dynasty), the King of Ryukyu started paying tribute to the imperial court of the Ming Dynasty. In return, Emperor Hongwu (the first emperor of the Ming Dynasty) sent imperial envoys to Ryukyu. In the following five centuries until 1866 (the fifth year of the reign of Emperor Tongzhi of the Qing Dynasty), the imperial courts of the Ming and Qing Dynasties sent imperial envoys to Ryukyu 24 times to confer titles on the Ryukyu King, and Diaoyu Dao was exactly located on their route to Ryukyu. Ample volume of records about Diaoyu Dao could be found in the reports written by Chinese imperial envoys at the time. For example, the Records of the Imperial Title-conferring Envoys to Ryukyu (Shi Liu Qiu Lu) written in 1534 by Chen Kan, an imperial title-conferring envoy from the Ming court, clearly stated that "the ship has passed Diaoyu Dao, Huangmao Yu, Chi Yu... Then Gumi Mountain comes into sight, that is where the land of Ryukyu begins." The Shi Liu Qiu Lu of another imperial envoy of the Ming Dynasty, Guo Rulin, in 1562 also stated that "Chi Yu is the mountain that marks the boundary of Ryukyu". In 1719, Xu Baoguang, a deputy title-conferring envoy to Ryukyu in the Qing Dynasty, clearly recorded in his book Records of Messages from Chong-shan (Zhong Shan Chuan Xin Lu) that the voyage from Fujian to Ryukyu passed Huaping Yu, Pengjia Yu, Diaoyu Dao, Huangwei Yu, Chiwei Yu and reached Naba (Naha) port of Ryukyu via Gumi Mountain (the mountain guarding the southwest border of Ryukyu) and Machi Island.

In 1650, the Annals of Chong-shan (Zhong Shan Shi Jian), the first official historical record of the Ryukyu Kingdom drafted under the supervision of Ryukyu's prime minister Xiang Xiangxian (Kozoken), confirmed that Gumi Mountain (also called Gumi Mountain, known as Kume Island today) is part of Ryukyu's territory, while Chi Yu (known as Chiwei Yu today) and the areas to its west are not Ryukyu's territory. In 1708, Cheng Shunze (Tei Junsoku), a noted scholar and the Grand Master with the Purple-Golden Ribbon (Zi Jin Da Fu) of Ryukyu, recorded in his book A General Guide (Zhi Nan Guang Yi) that "Gumi Mountain is the mountain guarding the southwest border of Ryukyu".

These historical accounts clearly demonstrate that Diaoyu Dao and Chiwei Yu belong to China and Kume Island belongs to Ryukyu, and that the separating line lies in Hei Shui Gou (today's Okinawa Trough) between Chiwei Yu and Kume Island. In 1579, Xie Jie, a deputy imperial title-conferring envoy of the Ming Dynasty, recorded in his book, Addendum to Summarized Record of Ryukyu (Liu Qiu Lu Cuo Yao Bu Yi) that he entered Ryukyu from Cang Shui to Hei Shui, and returned to China from Hei Shui to Cang Shui. Xia Ziyang, another imperial envoy of the Ming court, wrote in 1606 that "when the water flows from Hei Shui back to Cang Shui, it enters the Chinese territory." Miscellaneous Records of a Mission to Ryukyu (Shi Liu Qiu Za Lu), a book written in 1683 by Wang Ji, an imperial envoy of the Qing Dynasty, stated that "Hei Shui Gou", situated outside Chi Yu, is the "boundary between China and foreign land". In 1756, Zhou Huang, a deputy imperial envoy of the Qing Dynasty, recorded in his book, the Annals of Ryukyu (Liu Qiu Guo Zhi Lue), that Ryukyu "is separated from the waters of Fujian by Hei Shui Gou to the west".

The waters surrounding Diaoyu Dao are traditionally Chinese fishing ground. Chinese fishermen have, for generations, engaged in fishery activities in these waters. In the past, Diaoyu Dao was used as a navigation marker by the Chinese people living on the southeast coast.

2. Diaoyu Dao had long been under China's jurisdiction

In the early years of the Ming Dynasty, China placed Diaoyu Dao under its coastal defense to guard against the invasion of Japanese pirates along its southeast coast. In 1561 (the 40th year of the reign of Emperor Jiajing of the Ming Dynasty), An Illustrated Compendium on Maritime Security (Chou Hai Tu Bian) compiled by Zheng Ruozeng under the auspices of Hu Zongxian, the supreme commander of the southeast coastal defense of the Ming court, included the Diaoyu Dao Islands on the "Map of Coastal Mountains and Sands" (Yan Hai Shan Sha Tu) and incorporated them into the jurisdiction of the coastal defense of the Ming court. The Complete Map of Unified Maritime Territory for Coastal Defense (Qian Kun Yi Tong Hai Fang Quan Tu), drawn up by Xu Bida and others in 1605 (the 33rd year of the reign of Emperor Wanli of the Ming Dynasty) and the Treatise on Military Preparations. Coastal Defense II. Map of Fujian's Coastal Mountains and Sands (Wu Bei Zhi. Hai Fang Er. Fu Jian Yan Hai Shan Sha Tu), drawn up by Mao Yuanyi in 1621 (the first year of the reign of Emperor Tianqi of the Ming Dynasty), also included the Diaoyu Dao Islands as part of China's maritime territory.

The Qing court not only incorporated the Diaoyu Dao Islands into the scope of China's coastal defense as the Ming court did, but also clearly placed the islands under the jurisdiction of the local government of Taiwan. Official documents of the Qing court, such as A Tour of Duty in the Taiwan Strait (Tai Hai Shi Cha Lu) and Annals of Taiwan Prefecture (Tai Wan Fu Zhi) all gave detailed accounts concerning China's administration over Diaoyu Dao. Volume 86 of Recompiled General Annals of Fujian (Chong Zuan Fu Jian Tong Zhi), a book compiled by Chen Shouqi and others in 1871 (the tenth year of the reign of Emperor Tongzhi of the Qing Dynasty), included Diaoyu Dao as a strategic location for coastal defense and placed the islands under the jurisdiction of Gamalan, Taiwan (known as Yilan County today).

3. Chinese and foreign maps show that Diaoyu Dao belongs to China

The Roadmap to Ryukyu (Liu Qiu Guo Hai Tu) in the Shi Liu Qiu Lu written by imperial title-conferring envoy Xiao Chongye in 1579 (the seventh year of the reign of Emperor Wanli of the Ming Dynasty), the Record of the Interpreters of August Ming (Huang Ming Xiang Xu Lu) written by Mao Ruizheng in 1629 (the second year of the reign of Emperor Chongzhen of the Ming Dynasty), the Great Universal Geographic Map (Kun Yu Quan Tu) created in 1767 (the 32nd year of the reign of Emperor Qianlong of the Qing Dynasty), and the Atlas of the Great Qing Dynasty (Huang Chao Zhong Wai Yi Tong Yu Tu) published in 1863 (the second year of the reign of Emperor Tongzhi of the Qing Dynasty) all marked Diaoyu Dao as China's territory.

The book Illustrated Outline of the Three Countries written by Hayashi Shihei in 1785 was the earliest Japanese literature to mention Diaoyu Dao. The Map of the Three Provinces and 36 Islands of Ryukyu in the book put Diaoyu Dao as being apart from the 36 islands of Ryukyu and colored it the same as the mainland of China, indicating that Diaoyu Dao was part of China's territory.

The Map of East China Sea Littoral States created by the French cartographer Pierre Lapie and others in 1809 colored Diaoyu Dao, Huangwei Yu, Chiwei Yu and the Taiwan Island as the same. Maps such as A New Map of China from the Latest Authorities published in Britain in 1811, Colton's China published in the United States in 1859, and A Map of China's East Coast: Hongkong to Gulf of Liao-Tung compiled by the British Navy in 1877 all marked Diaoyu Dao as part of China's territory.

II.

Japan Grabbed Diaoyu Dao from China

Japan accelerated its invasion and external expansion after the Meiji Restoration. Japan seized Ryukyu in 1879 and changed its name to Okinawa Prefecture. Soon after that, Japan began to act covertly to invade and occupy Diaoyu Dao and secretly "included" Diaoyu Dao in its territory at the end of the Sino-Japanese War of 1894-1895. Japan then forced China to sign the unequal Treaty of Shimonoseki and cede to Japan the island of Formosa (Taiwan), together with Diaoyu Dao and all other islands appertaining or belonging to the said island of Formosa.

1. Japan's covert moves to seize Diaoyu Dao

In 1884, a Japanese man claimed that he first landed on Diaoyu Dao and found the island to be uninhabited. The Japanese government then dispatched secret facts-finding missions to Diaoyu Dao and attempted to invade and occupy the island. The above-mentioned plots by Japan triggered China's alert. On September 6, 1885 (the 28th day of the 7th month in the 11th year of the reign of Emperor Guangxu of the Qing Dynasty), the Chinese newspaper Shen-pao (Shanghai News) reported: "Recently, Japanese flags have been seen on the islands northeast to Taiwan, revealing Japan's intention to occupy these islands." But the Japanese government did not dare to take any further action for fear of reaction from China.

After the secret facts-finding missions to Diaoyu Dao, the governor of Okinawa Prefecture sent a report in secrecy to the Minister of Internal Affairs Yamagata Aritomo on September 22, 1885, saying that these uninhabited islands were, in fact, the same Diaoyu Tai, Huangwei Yu and Chiwe Yu that were recorded in the Records of Messages from Chong-shan (Zhong Shan Chuan Xin Lu) and known well to imperial title-conferring envoys of the Qing court on their voyages to Ryukyu, and that he had doubts as to whether or not sovereignty markers should be set up and therefore asked for instruction. The Minister of Internal Affairs Yamagata Aritomo solicited opinion from the Foreign Minister Inoue Kaoru on October 9. Inoue Kaoru replied in a letter to Yamagata Aritomo on October 21, "At present, any open moves such as placing sovereignty markers are bound to alert the Qing imperial court. Therefore, it is advisable not to go beyond field surveys and detailed reports on the shapes of the bays, land and other resources for future development. In the meantime, we will wait for a better time to engage in such activities as putting up sovereignty markers and embarking on development on the islands." Inoue Kaoru also made a special emphasis that "it is inappropriate to publicize the missions on official gazette or newspapers." As a result, the Japanese government did not approve of the request of Okinawa Prefecture to set up sovereignty markers.

The governor of Okinawa Prefecture submitted the matter for approval to the Minister of Internal Affairs once again on January 13, 1890, saying that Diaoyu Dao and other "above-mentioned uninhabited islands have remained under no specific jurisdiction", and that he "intends to place them under the jurisdiction of the Office of Yaeyama Islands." On November 2, 1893, the governor of Okinawa Prefecture applied once again for setting up sovereignty markers to incorporate the islands into Japan's territory. The Japanese government did not respond. On May 12, 1894, two months before the Sino-Japanese War, the secret facts-finding missions to Diaoyu Dao by Okinawa Prefecture came to a final conclusion, "Ever since the prefecture police surveyed the island in 1885 (the 18th year of the Meiji period), there have been no subsequent investigations. As a result, it is difficult to provide any specific reports on it... In addition, there exist no old records related to the said island or folklore and legends demonstrating that the island belongs to our country."

Japan's attempts to occupy Diaoyu Dao were clearly recorded in Japan Diplomatic Documents compiled by the Japanese Foreign Ministry. Relevant documents evidently show that the Japanese government intended to occupy Diaoyu Dao, but refrained from acting impetuously as it was fully aware of China's sovereignty over these islands.

Japan waged the Sino-Japanese War in July 1894. Towards the end of November 1894, Japanese forces seized the Chinese port of Lushun (then known as Port Arthur), virtually securing defeat of the Qing court. Against such backdrop, the Japanese Minister of Internal Affairs Yasushi Nomura wrote to Foreign Minister Mutsu Munemitsu on December 27 that the "circumstances have now changed", and called for a decision by the cabinet on the issue of setting up sovereignty markers in Diaoyu Dao and incorporating the island into Japan's territory. Mutsu Munemitsu expressed his support for the proposal in his reply to Yasushi Nomura on January 11, 1895. The Japanese cabinet secretly passed a resolution on January 14 to "place" Diaoyu Dao under the jurisdiction of Okinawa Prefecture.

Japan's official documents show that from the time of the facts-finding missions to Diaoyu Dao in 1885 to the occupation of the islands in 1895, Japan had consistently acted in secrecy without making its moves public. This further proves that Japan's claim of sovereignty over Diaoyu Dao does not have legal effect under international law.

2. Diaoyu Dao was ceded to Japan together with the Taiwan Island

On April 17, 1895, the Qing court was defeated in the Sino-Japanese War and forced to sign the unequal Treaty of Shimonoseki and cede to Japan "the island of Formosa (Taiwan), together with all islands appertaining or belonging to the said island of Formosa". The Diaoyu Dao Islands were ceded to Japan as "islands appertaining or belonging to the said island of Formosa". In 1900, Japan changed the name of Diaoyu Dao to "Senkaku Islands".
