Chinese author Wan Zhen of the Eastern Wu dynasty (222–280 CE) and a work titled Guangzhou Ji (Chronicles of Guangzhou) authored by Pei Yuan of the Jin dynasty (266–420 CE) described some southern islands, mainly Hainan.[7] The local government exercised jurisdiction over Hainan by sending patrolling naval boats.[8]
Naval forces of the Liu Song dynasty (420–479 CE) patrolled the southernmost island of Hainan.[9] In the Tang dynasty (618–907 CE), Hainan was placed under the administration and authority of the Qiongzhou Prefecture (now Hainan Province).[9] The Chinese administration of the South China Sea continued into the Song dynasty (960–1279 CE).[9]
Archaeologists have found Chinese made potteries porcelains and other historical relics from the Southern dynasties (420–589 CE), the Sui dynasty (581–619 CE), the Tang dynasty, the Song dynasty, the Yuan dynasty (1271–1368 CE), the Ming dynasty (1368–1644 CE) and later eras up to modern times on the South China Sea islands, where the material culture of the Austronesians (the Philippines, Indonesia, and so on) can also be found, suggesting that no nation had sovereignty over the high seas at the time but trade among the many polities of the region occurred.[9]
1734 – The Spanish colonial government published the first edition of the Velarde map. According to the Philippines, this map shows the territories of the Philippines including actual sovereignty over the Scarborough Shoal (called Panacot in the map) and the Spratly Islands (referred as Los Bajos de Paragua) and is the earliest map showing sovereignty over the said territories.[10][11]
1792 - The Spanish colonial government of the territory of the Philippines launched the first ever survey of Scarborough Shoal on May 4, 1792. The survey, Plano de la Navigacion, was taken by Alessandro Malaspina aboard the Sta. Lucia, with Filipino comrades.[12]

1883 – When the Spratlys and Paracels were surveyed by Germany in 1883, China issued protests.[20][21]
1884–1885 Sino-French War. In December 1884, alarmed by Japanese ambitions in Korea, Empress Dowager Cixi ordered her ministers to extricate China from the undeclared war with France that had broken out on 23 August. The Chinese agreed to implement the provisions of the May 1884 Tientsin Accord, which recognised France's protectorate over Vietnam. In return, the French dropped their longstanding demand for an indemnity for the Bắc Lệ ambush. After a flurry of negotiations in Paris in the first days of April 1885, peace was made on this basis.[22]
11 May 1884 – The Tientsin Accord or Li–Fournier Convention, concluded on 11 May 1884, was intended to settle an undeclared war between France and China over the sovereignty of Tonkin (northern Vietnam). The convention, negotiated by Li Hongzhang for China and capitaine de vaisseau François-Ernest Fournier for France, provided for a Chinese troop withdrawal from Tonkin in return for a comprehensive treaty that would settle details of trade and commerce between France and China and provide for the demarcation of its disputed border with Vietnam.[23][24]
9 June 1885 – The Treaty of Tientsin, signed on 9 June 1885, officially ended the Sino-French War. The unequal treaty restated in greater detail the main provisions of the Tientsin Accord, signed between France and China on 11 May 1884. As Article 2 required China to recognise the French protectorate over Annam and Tonkin established by the Treaty of Hue in June 1884, implicitly abandoning China's own claims to suzerainty over Vietnam, the treaty formalised France's victory in the Sino-French War.[24]
1885 – China officals declare its rights to the Paracels.[16]
1887 – In the 19th century, Europeans found that Chinese fishermen from Hainan annually visited the Spratly islands for part of the year, while in 1877 it was the British who launched the first modern legal claims to the Spratlys.[25][26]
1887 – The Chinese–Vietnamese Boundary Convention (formally, the Convention Respecting the Delimitation of the Frontier Between China and Tonkin) between France and the Qing Empire set the land boundary between Tonkin and China and sovereignty of a few small islands in the Gulf of Tonkin.[27][28][29] Some scholars, especially Chinese try to argue that The 1887 Convention recognised China claim over Spratly and Paracel islands because France relinquished its claims.[6][30][31] This was disputed[32][33] because the 1887 Convention between France and the Qing Empire set the coastal boundary in the Gulf of Tonkin but did not state that China was the owner of the Spratly and Paracel islands because these islands are not in the Gulf of Tonkin nor were administered by Tonkin, but were associated with the realm of Annam in central Vietnam by France.[34]
1898 – After the Spanish-American War, the Philippine Islands were ceded by Spain to the United States in the Treaty of Paris.[35] The treaty lines drawn were inaccurate, leading to the Spanish to retain sovereign control over the Spratly Islands, Scarborough Shoal, and parts of Tawi-Tawi. According to Filipino officials and commentators, this was later rectified in the 1900 Treaty of Washington where the mentioned territories were formally ceded to the United States as part of the territory of the Philippines.[11][10]
12 April 1898 – France seized Guangzhouwan as a treaty port according to the Treaty of 12 April 1898, on 27 May as Territoire de Kouang-Tchéou-Wan[36] and was effectively placed under the authority of the French Resident Superior in Tonkin (itself under the Governor General of French Indochina, also in Hanoi).[37] The French wanted to develop the port, which they called Fort-Bayard, to serve southern China. They retained control of the region until 1943 when the Japanese occupied the area during World War II. At the end of the war, the region returned briefly under French rule before being formally returned to China in 1946 by French leader Charles de Gaulle.[38] The old spellings "Tsankiang", "Chankiang" and "Tsamkong" were replaced by the pinyin romanisation "Zhanjiang" by the Chinese government in 1958.
1900 - The Treaty of Washington was signed on November 7, 1900, and came into effect on March 23, 1901, when the ratifications were exchanged. Before the treaty was signed, the territories of Scarborough Shoal, the Spratly Islands, and parts of Tawi-Tawi continued to be under Spanish sovereignty due to the 1898 Treaty of Paris. The 1900 Washington Treaty added that "all islands belonging to the Philippine Archipelago, lying outside the lines described in Article III of [the 1898 Treaty of Paris] and particularly to the islands of Cagayan [Mapun], Sulu and Sibutu" to the formal cession by Spain to the United States. According to the Philippines, this included Scarborough Shoal, the Spratly Islands, and the remaining parts of Tawi-Tawi within the country's sovereign territory.[39][10]

1932 - France occupied the Paracels for the French Union. China sent a Note Verbale to France stating that the Paracels were the "southernmost" territory of China.[46][47][48]
1933 - France claimed six islands in the Spratly for the French Union. China did not protest the claim as it considered the Paracels as its southernmost territory through a 1932 Note Verbale sent by China to France.[46][47][48][49][44]
1935 - The Philippines adopted the 1935 Philippine Constitution, which reiterates the territory of the Philippines as per the 1898 Treaty of Paris, the 1900 Treaty of Washington, and the 1930 US-UK Treaty to include Scarborough Shoal and the Spratly Islands.[50]
June 1937 – China sends Huang Qiang, the chief of Chinese military region no. 9 on a secret tour in four islands in the Amphitrite Group of the Paracels. His boat was loaded with 30 backdated sovereignty markers. Because the mission was confidential Huang Qiang carried no markers dated 1937.

Nanjing then declared both archipelagoes to be part of Guangdong Province.[56][57]
1946 – The ROC established garrisons on both Woody (now Yongxing / 永兴) Island in the Paracels and Taiping Island in the Spratlys. France protested. It tried but failed to dislodge Chinese nationalist troops from Yongxing Island/Woody Island (the only habitable island in the Paracels), but were able to establish a small camp on Pattle (now Shanhu / 珊瑚) Island in the southwestern part of the archipelago.[57][58][59] The Republic of China drew up The Southern China Sea Islands Location Map, marking the sea with 11 lines in 1947.[40] The Americans discouraged the Philippines in its claim to the Spratlys to avoid tensions with China. The Spratly was outside the treaty lines made in the 1898 Treaty of Paris,[58] However, the supplemental 1900 Treaty of Washington modified that to include to any and all islands belonging to the Philippine Archipelago lying outside those lines, and former Philippine Supreme Court justice Antonio Carpio has asserted that this includes the Spratlys.[60]

Nothing was said explicitly about offshore archipelagos. Arguably it was understood that the Republic of Vietnam (South Vietnam) inherited of all French Indochina's Vietnamese territories below the 17th Parallel.[65][66]
1956 – North Vietnam Communist government formally accepted that the Paracel and Spratly islands were historically Chinese. The PLA reestablished a Chinese garrison on Yongxing Island in the Paracels, while the Republic of China (Taipei) put troops back on Taiping Island in the Spratlys.
