Timeline of events

1000 century BC–2nd century CE

The Sa Huynh culture flourished in coastal South China Sea, especially in southern to central Vietnam, from Mekong Delta to Quang Binh province. The people that support Sa Huynh civilization were sea faring Austronesian-speaking people. The Sa Huynh relics can be found in several sites on the coasts of South China Sea, from Palawan in the Philippines to Orchid Island near Taiwan, suggesting that they sailed, settled and traded around the coasts of South China Sea.^[1]

3rd century BC

It has been claimed by the People's Republic of China on the argument that since 200 BC Chinese fishermen have used the Spratly islands.^[2]

3rd century

Two famous Chinese books authored by Wan Zhen of the Eastern Wu State and published during the Three Kingdoms period (220–280 AD) and a work titled Guangzhou Ji (Chronicles of Guangzhou) authored by Pei Yuan of the Jin Dynasties described the Paracel and Spratly islands.^[3] The local government of the Jin Dynasties exercised jurisdiction over the islands by sending patrolling naval boats to the surrounding sea areas.^[4]

5th–13th centuries

Naval forces of the Song State of the Southern Dynasties (420–479 AD) patrolled the Paracel and Spratly islands.^[5] In the Tang dynasty (618–907 AD), the islands were placed under the administration and authority of the Qiongzhou Perfecture (now Hainan Province).^[5] Chinese administration of the South China Sea continued into the North and South Song dynasties (970–1279).^[5]

Archaeologists have found Chinese made potteries porcelains and other historical relics from the Southern dynasties (420–589), the Sui dynasties (581–618), the Tang dynasty (618–907), the Song Dynasties (960–1279), the Yuan dynasties (1206–1368), the Ming dynasty (1368–1644) and later eras up to modern times on the South China Sea islands.^[5]

6th–15th centuries

The South China Sea was known as the "Champa Sea" by sailors and traders in the region. It was named after a Hindu thalassocratic empire Champa that flourished in the area around that period.^[1]

19th century

• 1816 – Vietnamese emperor Gia Long ordered a company to the Paracel Islands to make a survey and draw a map.^[6][7]
• 1835 – Vietnam erects a pagoda in the Paracel Islands^[8]
• 1876 – China makes its earliest documented claim to the Paracel Islands
• 1883 – When the Spratlys and Paracels were surveyed by Germany in 1883, China issued protests.^[9][10]
• 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. Important French victories in Tonkin and Formosa in February and early March 1885 stengthened her desire to end the Sino-French War, and although the Chinese won an unexpected victory in Tonkin in late March, defeating General de Négrier's 2nd Brigade at Bang Bo and reoccupying Lang Son, this success was counterbalanced by the simultaneous French capture of the Pescadores Islands. China's position in early April 1885 was critical. Seizing the opportunity offered by the fall of the Ferry ministry, 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 Bac Le Ambush. After a flurry of negotiations in Paris in the first days of April 1885, peace was made on this basis.^[11]
• 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 Hung-chang 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.^[12][13]
• 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 her own claims to suzerainty over Vietnam, the treaty formalised France's victory in the Sino-French War.^[13]
• 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.^[14][15]
• 1887 – The Convention Respecting the Delimitation of the Frontier Between China and Tonkin between France and the Qing Empire set the maritime boundary in the Gulf of Tonkin.^[16][17][18] The 1887 Chinese-Vietnamese Boundary convention signed between France and China after the Sino-French War said that China was the owner of the Spratly and Paracel islands.^[2][9][19] The 1887 Convention Respecting the Delimitation of the Frontier Between China and Tonkin between France and the Qing Empire set the coastal boundary in the Gulf of Tonkin but did not said that China was the owner of the Spratly and Paracel islands because these islands are not in the Gulf of Tonkin nor was administered by Tonkin but belonged to the realm of Annam in Central Vietnam.^[20] The purpose of this treaty was a better control of the border for it match the Ka Long river in Móng Cái coastal city, but doing so, the French gave a 7 Vietnamese fishermens villages enclave to China.^[21] Currently there are some suggestions that this part of Fangchenggang district, Guangxi, China belong to Vietnam, especially after North Vietnam was established and announced to cancel all treaties signed by French colonial Vietnam. Thus Fangchenggang was supposed to be returned to Quang Ninh province in Vietnam, but this has not been done yet. Most of people living in the area are Vietnamese fishermen who became one of the 56 ethnic groups of China, known as ethnic Vietnamese people of China or Gin people.
• 1898 – The Philippine Islands were ceded by Spain to the United States in the Treaty of Paris following the Spanish–American War. The Spratly Islands were not part of the Philippines per the Treaty.
• 12 April 1898 - France seized Guangzhouwan as a treaty port, and take its own concession in the treaty port of Shanghai. Kwangchow Wan, (Guangzhouwan), was leased by China to France for 99 years (or until 1997, as the British did in Hong Kong's New Territories), according to the Treaty of 12 April 1898, on 27 May as Territoire de Kouang-Tchéou-Wan, to counter the growing commercial power of British Hong Kong^[22] 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); the French Resident was represented locally by Administrators.^[23] The French wanted to develop the port, which they called Fort-Bayard, to serve southern China, in parts where France had exclusive rights to railway and mineral development. Their efforts, however, were hindered by the poverty of the surrounding land. The French 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 General Charles de Gaulle, then French head of state. The old spellings "Tsankiang", "Chankiang" and "Tsamkong" were replaced by the pinyin romanisation "Zhanjiang" by the Chinese government in 1958. Zhanjiang is headquarters of the South Sea Fleet of the People's Liberation Army Navy South Sea Fleet.^[24] The Zhanjiang Port is one of the eight major ports in China, with an annual throughput of more than 2,600 million tons. As a natural port, it has about 60 kilometers depth and three islands outside to support.^[25]

1901–1937

• 1902 – China sends naval forces on inspection tours of the Paracel Islands to preempt French claims.^[26] Philippine sources claimed that "Several authors writing about the Chinese claim to the Paracel Islands have dated the first official Chinese expedition to these islands to 1902. However, none of these writers have been able to show any records of this expedition taking place. In fact, Chinese records show that the expedition never happened."^[27][28]
• 1907 – China sends another naval force, this time to plan for resource exploitation.^[26]
• 1911 – The newly formed Republic of China, successor state to the Qing Dynasty, moves administration of the Paracel Islands to Hainan,^[26] which would not become a separate Chinese province until 1988.
• 1917 - Japanese exploited phosphate deposits (guano) in the main Spratly island, Itu Aba. It was noticed by Japan in July 1938 to the France's ambassador in Tokyo who was recalling the earlier annexation of the Spratly by France.^[29]
• 1927 – Japan makes its earliest documented claim to the Paracel and Spratly Islands
• 1928 – The Republic of China states that the Paracel Islands are the southernmost limits of its territory
• 1931 – France claims the Paracel Islands^[29]
• 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. The team buried a total of 12 backdated sovereignty markers, including 3 true old markers dating from the Qing dynasty, bearing the date 1902, gathered in the city of Guangdong:
  • On Lin Dao (Woody Island): 2 markers dated 1921
  • On Bei Dao (North Island): 2 markers from 1902 and 4 dated 1912
  • On Ling Zhou Dao (?): 1 marker from 1902, 1 dated 1912 and 1 dated 1921.
  • On Shi Dao (Rocky Island): 1 marker dated 1912.

Philippine sources claim that PLA troops and PRC archaeologists 'discovered' these markers between 1974 and 1979 and the fiction of the primary sources less 1902 expedition was created.

^[27][28]

• 31 March 1939 - Tokyo, notified to the ambassador of France that the Spratly Islands were inhabited by Japanese, were under the Japanese jurisdiction and administratively attached to the territory of Formosa (Japan); the occupation was carried out by a police detachment.^[29]

World War II

• 1939 – Japan occupies the islands and takes control of the South China Sea. The Spratlys and the Paracels were conquered by Japan in 1939. Japan had set military bases on Woody and Pattle islands in the Paracels and Itu Aba in the Spratlys. Japan administered the Spratlys via Taiwan's jurisdiction and the Paracels via Hainan's jurisdiction.^[30]
• 2 July 1945 – Woody Island surrendered to the USS Cabrilla submarine after having been attacked by US forces on 6 February and 8 March.^[20]
• 20 November 1945 – A US Navy reconnaissance mission landed on Itu Aba and found the Japanese forces had already pulled out.^[31]

Used since 22 August 1956 until 1975, when replaced by another one from the Socialist Republic of Vietnam (successor state after the Fall of Saigon)

• 1945 – In accordance with the Cairo and Potsdam Declarations and with American help, the armed forces of the Republic of China government at Nanjing accepted the surrender of the Japanese garrisons in Taiwan, including the Paracel and Spratly Islands. Nanjing then declared both archipelagoes to be part of Guangdong Province.^[32][33]
• 1946 – The R.O.C. established garrisons on both Woody (now Yongxing / 永兴) Island in the Paracels and Taiping Island in the Spratlys. France protested. The French 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.^[33][34][35] The Republic of China drew up The Southern China Sea Islands Location Map, marking the national boundaries in the sea with 11 lines, showing the U shaped claim on the entire South China Sea, and showing the Spratly and Paracels in Chinese territory, in 1947.^[26] The Americans reminded the Philippines at its independence in 1946 that the Spratlys was not Philippine territory, both to not anger Chiang Kai-shek in China and because the Spratlys were not part of the Philippines per the 1898 treaty Spain signed with America.^[34]
• 1950 – After the Chinese nationalists were driven from Hainan by the People's Liberation Army (PLA), they withdrew their garrisons in both the Paracels and Spratlys to Taiwan.
• 1952 – Japan renounced any claims of sovereignty over the Spratly and Paracel archipelagos in accordance with Article 2 Clause (f) of the San Francisco Peace Treaty, but no beneficiary was designated.^[36]
• 1954 – The Geneva Accords, which China was a signatory, settled the First Indochina War end. French Indochina was split into three countries: Laos, Cambodia, and Vietnam. Vietnam was to be temporarily divided along the 17th Parallel. Chapter I, Article 4 say: "The provisional military demarcation line between the two final regrouping zones is extended into the territorial waters by a line perpendicular to the general line of the coast. All coastal islands north of this boundary shall be evacuated by the armed forces of the French Union, and all islands south of it shall be evacuated by the forces of the People's Army of Viet-Nam."^[37] On 26 October 1955, the Republic of Vietnam "South Vietnam" replaced the State of Vietnam (part of the French Union) and inherit of its rights. Nothing was said explicitly about offshore archipelagos, which was of small interest by that times, it was clearly understood by all the parties that the Republic of Vietnam inherit of all the French Indochina's Vietnamese territories under the 17th Parallel. As the Paracel and the Spratly archipelagos (which lay below the 17th parallel) were part of the French Indochina since 1933, they were part of "South Vietnam" territory. The French bestowed its titles, rights, and claims over the two island chains to the Republic of Vietnam.^[38][39]
• 1956 – North Vietnam Communist government formally accepted that the Paracel and Spratly islands were historically Chinese. But, that same year, South Vietnam reopened the abandoned French camp on Shanhu Island in the Paracels and announced that it had annexed the Paracel archipelago as well as the Spratlys. About the same time, 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.^[40] In 1956, Cloma proclaimed the establishment of a new country, "Freedomland" in the Spratly Islands. The sole function of Freedomland turned out to be issuing postage stamps to collectors. Cloma's announcement of Freedomland caused both Beijing and Taipei to reiterate China's claims to the Spratlys. Taipei sent troops to drive Cloma off Taiping Island. Its forces are still there. Cloma's proclamation of Freedomland was legal in the Philippines because, as Manila noted in its reply to protests of Cloma's actions from Beijing, Saigon, and Taipei, the Philippines had made no claim of its own to the Spratlys.
• 4 September 1958 – China published "Declaration of the Government of the People's Republic of China on China's Territorial Sea published on 4 September 1958" to lawfully describe true meaning of "nine-dotted line on South China Sea".
• 14 September 1958 – Communist Vietnamese Premier Pham Van Dong sent Premier Zhou Enlai a formal diplomatic saying respect China's decision on South China Sea.

• 1970 – China occupies Amphitrite Group of the Paracel Islands
• 1971 – Philippines announces claim to islands adjacent to its territory in the Spratlys, which they named Kalayaan, which was formally incorporated into Palawan Province in 1972. The Philippines President Marcos announced the claims after Taiwanese troops attacked and shot at a Philippine fishing boat on Itu Aba.^[41]
• 1972 – Bureau of Survey and Cartography under the Office of the Premier of Vietnam printed out "The World Atlas" says "The chain of islands from the Nansha and Xisha Islands to Hainan Island, Taiwan Island, the Penghu Islands and the Zhoushan Islands ... are shaped like a bow and constitute a Great Wall defending the China mainland."^[42]
• 1974 – South Vietnam attempted to enforce its claims to sovereignty by placing settlers in the Spratlys and expelling Chinese fishermen from the southwestern Paracels. In the ensuing naval battle at Shanhu Island, China defeated Vietnamese forces. This enabled Beijing to extend its control to the entire Paracel archipelago, where it has not been effectively challenged since. China ousts South Vietnamese forces from the Crescent Group of the Paracel Islands at the Battle of the Paracel Islands.
• 14 February 1975, regretting the agreement with China in 1956. The Communist Vietnamese government reclaims to the Spratly and Paracel archipelagos.
• 11 June 1978 - President Ferdinand Marcos, by virtue of the Presidential Decree No. 1596, asserted that islands designated as the Kalayaan Island Group and comprising most of the Spratly Islands are subject to the sovereignty of the Philippines,^[43] and by virtue of the Presidential Decree No. 1599 issued on 11 June 1978 claimed an Exclusive Economic Zone (EEZ) up to 200 nautical miles (370 km) from the baselines from which their territorial sea is measured.^[44]
• 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. In the early 1980s, as Beijing, Kuala Lumpur, Manila, and Taipei protested, Vietnam resumed vigorous settlement and garrisoning of the Spratlys.

1980s

• 8 May 1984 – the Philippines ratified the 1982 Third United Nations Convention on the Law of the Sea (UNCLOS III) and declared themselves an archipelagic state.^[45] The Philippines claimed all the Spratly islands and reefs lying within its 200 Nautical mile Exclusive Economic Zone including Mabini (Johnson South Reef).^[46]
• 1984年小平提出了两个选项："一个办法是我们用武力统统把这些岛收回来；一个办法是把主权问题搁置起来，共同开发。"

Translation: In 1984, Deng Xiaoping raised two options: "One method is that we use force to get these islands back. Another is to shelve the sovereignty issue, co-develop the place."

• March 1987 – Mr Luo Yuru was China's State-Member Representative at the IOC - 14th Session of the Assembly of the Intergovernmental Oceanographic Commission. During the meeting of the IOC, UNESCO 17 March – 1 April in Paris, the Delegate of the People'Republic of China, speaking higly of GLOSS (Global Sea Level Observing System), noted a few mistakes in the text of Document IOC/INF-663 rev.; for instance, "Taiwan" is listed as a "country" in relevant Tables contained in the Document.^[47] The scientists from the GLOSS, who did not know that Taiwan is not a "country", agreed that China will install few tide gauges on "its coasts", in East China Sea and on its "Nansha islands" in South China Sea as they did not know it was a disputed area. Scientists of this era could not understand that Taiwan had an island in the Spratly but China (PRC) had none although it says it had.^[48] In April 1987, the PRC chose to build a weather station on Fiery Cross reef as the reef was large enough for the purpose, and it was isolated from other disputed islands and reefs. On the contrary, Johnson South Reef is inside Philippines claimed 200 NM EEZ and close to Sin Cowe Island inhabited by Vietnamese in the same Union Banks drowned atoll; clearly a disputed area.
• 14 March 1988 – China defeats the Vietnamese navy in the Johnson South Reef Skirmish on Mabini reef (Johnson South Reef), killing 64 young Vietnamese, most of them unarmed,^[49][50][51] after the Vietnamese tried to intercept a Chinese force commissioned by UNESCO to build a tidal gauge station^[47] in the Philippines claimed 200 Nautical mile Exclusive Economic Zone.^[46]
