ii. China has always been resolute in upholding its territorial sovereignty and maritime rights and interests in the South China Sea

23. China's sovereignty over Nanhai Zhudao had never been challenged before the 20th century. When France and Japan invaded and illegally occupied by force some islands and reefs of China's Nansha Qundao in the 1930s and 1940s, the Chinese people rose to fight back strenuously and the Chinese government took a series of measures to defend China's sovereignty over Nansha Qundao.

24. In 1933, France invaded some islands and reefs of Nansha Qundao and declared "occupation" of them in an announcement published in Journal Officiel, creating the "Incident of the Nine Islets". The French aggression triggered strong reactions and large scale protests from all walks of life across China. The Chinese fishermen living on Nansha Qundao also took on-site resistance against the French aggression. Chinese fishermen Fu Hongguang, Ke Jiayu, Zheng Landing and others cut down the posts flying French flags on Taiping Dao, Beizi Dao, Nanwei Dao, Zhongye Dao and others.

25. Shortly after this Incident happened, the Chinese Ministry of Foreign Affairs made clear through its spokesperson, referring to the relevant islands of Nansha Qundao, that "no other people but Chinese fishermen live on the islands and they are recognized internationally as Chinese territory". The Chinese government made strong representations to the French government against its aggression. And in response to the French attempt to trick Chinese fishermen into hanging French flags, the government of Guangdong Province instructed that administrators of all counties should issue public notice forbidding all Chinese fishing vessels operating in Nansha Qundao and relevant waters from hanging foreign flags, and Chinese national flags were distributed to them to be hung on Chinese fishing vessels.

26. China's Committee for the Examination for the Land and Sea Maps, which was composed of representatives of the Ministry of Foreign Affairs, Ministry of the Interior, Ministry of the Navy and other institutions, reviewed and approved the names of individual islands, reefs, banks and shoals of Nanhai Zhudao, compiled and published Zhong Guo Nan Hai Ge Dao Yu Tu (Map of the South China Sea Islands of China) in 1935.

27. Japan invaded and illegally occupied Nanhai Zhudao during its war of aggression against China. The Chinese people fought heroically against the Japanese aggression. With the advance of the World's Anti-Fascist War and the Chinese People's War of Resistance against Japanese Aggression, China, the United States and the United Kingdom solemnly demanded in the Cairo Declaration in December 1943 that all the territories Japan had stolen from the Chinese shall be restored to China. In July 1945, China, the United States and the United Kingdom issued the Potsdam Proclamation. That Proclamation explicitly declares in Article 8: "The terms of the Cairo Declaration shall be carried out."

28. In August 1945, Japan announced its acceptance of the Potsdam Proclamation and its unconditional surrender. In November and December 1946, the Chinese government dispatched Colonel Lin Zun and other senior military and civil officials to Xisha Qundao and Nansha Qundao to resume exercise of authority over these Islands, with commemorative ceremonies held, sovereignty markers re-erected, and troops garrisoned. These officials arrived at these islands on four warships, namely Yongxing, Zhongjian, Taiping and Zhongye. Subsequently, the Chinese government renamed four islands of Xisha Qundao and Nansha Qundao after the names of those four warships.

29. In March 1947, the Chinese government established on Taiping Dao Nansha Qundao Office of Administration and placed it under the jurisdiction of Guangdong Province. China also set up a meteorological station and a radio station on Taiping Dao, which started broadcasting meteorological information in June of that year.

30. On the basis of a new round of geographical survey of Nanhai Zhudao, the Chinese government commissioned in 1947 the compilation of Nan Hai Zhu Dao Di Li Zhi Lüe (A Brief Account of the Geography of the South China Sea Islands), reviewed and approved Nan Hai Zhu Dao Xin Jiu Ming Cheng Dui Zhao Biao (Comparison Table on the Old and New Names of the South China Sea Islands), and drew Nan Hai Zhu Dao Wei Zhi Tu (Location Map of the South China Sea Islands) on which the dotted line is marked. In February 1948, the Chinese government officially published Zhong Hua Min Guo Xing Zheng Qu Yu Tu (Map of the Administrative Districts of the Republic of China) including Nan Hai Zhu Dao Wei Zhi Tu (Location Map of the South China Sea Islands).
