Timeline of the South China Sea dispute

It has been claimed by the People's Republic of China that since 200 BCE Chinese fishermen have used the Spratly islands. == 3rd–13th centuries ==

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. The local government exercised jurisdiction over Hainan by sending patrolling naval boats. Naval forces of the Liu Song dynasty (420–479 CE) patrolled the southernmost island of Hainan. In the Tang dynasty (618–907 CE), Hainan was placed under the administration and authority of the Qiongzhou Prefecture (now Hainan Province). The Chinese administration of the South China Sea continued into the Song dynasty (960–1279 CE). The archaeological record of the South China Sea islands indicates occupation by a variety of cultures over the past 1500 years, suggesting that no nation had consistent sovereignty over the high seas at these times and that trade among the many polities of the region occurred. Evidence includes Chinese-made pottery, porcelain 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), along with Austronesian materials, including by peoples from the Philippines, Indonesia, and others of the region. == 18th century ==

• 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. • 1792 - The Spanish colonial government of the territory of the Philippines launched the first ever survey of Scarborough Shoal on 4 May 1792. The survey, Plano de la Navigacion, was taken by Alessandro Malaspina aboard the Sta. Lucia, with other Filipinos. == 19th century ==

• 1802 – Annamese emperor Gia Long creates the "Dio Hoang Sa" (Company of the Paracels). • 1816 – Gia Long orders a mapping survey of the Paracel Islands. The Annamese emperor never claimed any islands aside from the Paracels, where the Annamese flag was planted on Pattle Island. • 1830 – The first maps are published by the Annamese kingdom under Emperor Minh Mạng that include "Thruong Sa" (Spratly) Islands as part of its territory. • 1836 – Annam erects ten 5-metre steles with inscriptions claiming the Paracels. • 1876 – Guo Song Tao, China's ambassador to Europe, makes an unofficial claim to "Bailasu Dao" (the phonetic translation of the Paracel Island). • 1883 – During a Gemran survey of the Spratlys and Paracels, China issues protests. • 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. • 1885 – Chinese officials declare its rights to the Paracels. • 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. Some scholars, especially Chinese ones, try to argue that the 1887 convention recognised a Chinese claim over the Spratly and Paracel islands, because France relinquished its claims. This was disputed due to the fact that the 1887 convention set the coastal boundary in the Gulf of Tonkin, but did not state that China was the owner of the Spratly and Paracel islands, as these islands are not in the Gulf of Tonkin, but were associated with the realm of Annam in central Vietnam by France. • 1898 – After the Spanish-American War, the Philippines were ceded by Spain to the United States in the Treaty of Paris. • 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 the 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" were to be part of the formal cession by Spain to the United States. According to the Philippines, this included the Scarborough Shoal, the Spratly Islands, and the remaining parts of Tawi-Tawi within the country's sovereign territory. == 1901–1937 ==

• 1902 – China sends naval forces on inspection tours of the Paracel Islands to preempt French claims.

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. • 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. • June 1937 – China sends Huang Qiang, the chief of Chinese military region No. 9 on a secret tour to 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 to 1937. The team buried a total of 12 backdated sovereignty markers, including some actual old markers dating from the Qing dynasty, bearing the date 1902, which were gathered in the city of Guangdong. • 1938 - Secretary Cordell Hull of the US State Department issued a Memorandum on 27 July 1938 to Harry Woodring, Secretary of War, stating that Scarborough Shoal "should be regarded as included among the islands ceded to the United States by the American-Treaty of November 7, 1900," referring to the 1900 Treaty of Washington. == World War II ==

Their action was stopped by the armed forces of the Republic of China (Taiwan), which destroyed and confiscated Freedomland properties and resumed its garrison of Itu Aba.

In the ensuing Battle of the Paracel Islands, China defeated Vietnamese forces. China ousts South Vietnamese forces from the Crescent Group, enabling Beijing to extend its control to the entire Paracel archipelago. The "Operation Tran Hung Dao 48" was a campaign conducted by the Republic of Vietnam Navy from 30 January 1974 to station troops on unoccupied islands to assert Vietnam's sovereignty over the Spratly archipelago after the Battle of the Paracel Islands. • 14 February 1975, regretting the agreement with China in 1956, the Communist Vietnamese government reclaims the Spratly and Paracel archipelagos. and by virtue of the Presidential Decree No. 1599 issued on 11 June 1978 claimed an Exclusive Economic Zone (EEZ) up to from the baselines from which their territorial sea is measured. • 1979 – Hanoi (now the capital of a united Vietnam) adopted South Vietnam's position, and claimed sovereignty over all the islands in the South China Sea.
