🏳 Spratly Islands

An extensive sea-based trade network was established by animist indigenous Austronesian peoples, later expanding to states in present-day Brunei, Malaysia, Singapore, Thailand, Indonesia, Cambodia and Vietnam. The Spratly archipelago lay within this early maritime sphere, marking the region's long history of seaborne exchange.

Members of the seafaring Sa Huỳnh culture migrated westward and may have passed through the Spratly Islands en route to Vietnam. They were forebears of the Cham people, who founded the Old Champa kingdom in mainland Southeast Asia.

The Mao Kun map, dating from Zheng He's early fifteenth-century voyage, marked Shixing Shitang, taken by some authors to mean the Spratlys. Such early Chinese cartographic references are central to later sovereignty arguments, though scholars differ over which islands were meant.

Champa had historically maintained a large presence in the South China Sea before Vietnamese invasion shattered its power. The eclipse of Champa removed a maritime polity from the region and underpins later Vietnamese territorial arguments.

Maps compiled in 1724, 1755, 1767, 1810 and 1817 retained the territory inherited from Ming depictions, but the Qing never officially claimed jurisdiction over the islands. The distinction between cartographic depiction and formal claim remains contested in the modern dispute.

The early European chart left the region then known as the Dangerous Ground unsurveyed, though some western islands and shoals were marked. It illustrates how little European powers knew of the archipelago before systematic hydrography.

The East India Company hydrographer issued [South] China Sea, Sheet 1 after a survey by Captain Daniel Ross, giving the first credible delineation of the archipelago. A later 1859 edition named Spratly Island as Storm Island, aiding navigation through the Dangerous Ground.

Vietnam finally absorbed the remaining Cham territories, provoking a jihad declared by Katip Suma; resistance was crushed by 1835. Champa's historical maritime reach in the South China Sea remains politically sensitive for Vietnam's own claims.

A Vietnamese map of 1834 combined the Spratly and Paracel groups into a single region, and according to Hanoi maps recorded Bãi Cát Vàng, the Golden Sandbanks, as early as 1838. These records form the documentary basis of Vietnam's historic claim.

The British whaling captain's sighting gave the archipelago the English name by which it is most widely known. European mariners visited the group only sporadically through the nineteenth century and showed little interest in possession.

British claims were the earliest modern legal assertions over the archipelago, at a time when Chinese fishermen from Hainan were annually sojourning on the islands. The precedent complicates later competing narratives of first occupation.

German boats surveying the two archipelagos withdrew after protests from the Guangdong authorities, according to Chinese accounts. Western scholars question the episode's verifiability, noting the German Admiralty published charts of the Paracels in 1885 from an expedition of 1881–84.

Concluded after the Sino-French War, the convention drew a line dividing islands between China and Vietnam in the Gulf of Tonkin. Some Chinese scholars read it as recognising Chinese sovereignty over the Paracels and Spratlys, while France's notes of 1933 and 1937 insisted it covered only the Móng Cái area.

The concession represents one of the earliest documented commercial exploitations of the archipelago's resources. Guano extraction was the principal economic use of the islets before oil, gas and fisheries became the focus.

The treaty by which the United States acquired the Philippines did not include the Spratly Islands within the ceded territory. This omission has been cited ever since against Philippine claims, including by American officials in 1946.

About 45 of the islands are occupied by relatively small numbers of military forces from China, Malaysia, the Philippines, Taiwan and Vietnam, garrisons built up progressively from the 1950s onwards.

The Spratlys consist of more than 100 small islands or reefs surrounded by rich fishing grounds and potentially by gas and oil deposits. They are claimed in their entirety by China, Taiwan and Vietnam, while portions are claimed by Malaysia and the Philippines.

Chinese naval forces toured the islands in 1902 and 1907, leaving flags and markers as tokens of possession. The Qing's successor, the Republic of China, subsequently claimed the Spratly and Paracel islands under the jurisdiction of Hainan.

France occupied a number of the Spratlys including Taiping Island, built weather stations on two islands, and administered them as part of French Indochina. The Republic of China protested, noting that French warships had found Chinese fishermen on nine of the islands.

The ROC formally proclaimed sovereignty in response to the French occupation of the archipelago. The declaration established the continuity of Chinese claims later inherited by both Taipei and Beijing.

Japan occupied the Paracels and Spratlys from February 1939 and, on 30 March 1939, placed the New Southern Islands under Japanese authority in Taiwan, annexing the Paracels via Hainan. The islands served as a submarine base for the occupation of Southeast Asia until August 1945.

With the Allied powers assigning the ROC to accept Japanese surrenders in the area, parts of the Paracels and Spratlys came again under Chinese control, though no successor was formally named to the islands. The ambiguity of the 1945 settlement underlies all subsequent disputes.

In November 1946 the ROC sent naval vessels to take control, choosing the largest and only habitable island as its base and renaming it Taiping after the warship. The garrison, aimed at blocking French claims, is treated as the basis of an 'effective occupation' of the Spratlys.

The 1947 map placed the Spratlys and Paracels inside Chinese territory, creating the nine-dash line inherited by both Taipei and Beijing. It remains the cartographic foundation of the most expansive claims in the dispute.

Following their retreat to Taiwan and the founding of the People's Republic of China, Nationalist forces pulled out of most of the Spratlys and Paracels, quietly evacuating Taiping Island in 1950. The vacuum invited fresh claims from other parties.

Japan gave up the Spratlys along with the Paracels, Pratas and other captured islands, prompting the Republic of China to reassert its claim. At the conference South Vietnam declared Vietnamese sovereignty while North Vietnam supported China's authority.

After the French defeat ending the First Indochina War, the South Vietnamese government took over the Trường Sa administration, with French rights bestowed on the RoV in accordance with the Geneva Accords. This forms the legal chain for Vietnam's contemporary claim.

The Filipino adventurer claimed part of the Spratlys as his own and uprooted a Republic of China flag on Itu Aba. His action prompted Taiwan to re-garrison Taiping Island the same year, a presence maintained thereafter.

Hanoi protested against Taiwanese military drills conducted from Taiping Island. The demand continued a pattern of Vietnamese objections to Taipei's fortification of the largest natural feature in the archipelago.

Though not a claimant, Washington reported conducting FONOPs against what it deemed excessive and illegal claims by states including China, Malaysia, the Philippines, Taiwan and Vietnam. The operations inserted an external military power into the dispute's balance.

On 12 July 2016 the tribunal found largely for the Philippines, holding that China had never exercised exclusive control within the nine-dash line, criticising its land reclamation for severe harm to coral reefs, and classing Taiping Island and other features as rocks without a 200-nautical-mile EEZ. The award was final and non-appealable, but China and Taiwan both rejected it; by November 2023 twenty-six governments supported it and eight opposed.

Airbus photographs published on 16 April 2015 showed a runway covering much of the reclaimed reef, while scores of dredgers converted Fiery Cross and other reefs into military facilities. The works transformed submerged features into usable bases and were seen as a strategic threat by Vietnam and the Philippines.

Vietnam rammed a Chinese vessel on 2 May over the drilling platform while the Philippines detained eleven Chinese fishermen, amid an American presidential visit and a joint Philippine-American exercise. Taiwanese commentary accused Washington of inciting the confrontation behind the scenes.

Malaysian authorities displayed no concern, with Defence Minister Hishammuddin Hussein suggesting cooperation with China and telling ASEAN, America and Japan that Malaysia did not share their enmities. Kuala Lumpur's stance later hardened as China encroached on its territorial waters.

Manila challenged China's historic rights claims within the nine-dash line before a tribunal constituted under Annex VII, with the Permanent Court of Arbitration acting as registry. It was the first attempt to resolve the Spratly dispute through binding international adjudication.

Taiwan's operator brought satellite-linked mobile service to the largest of the Spratly features. The installation supported the garrison and underlined Taipei's continuing administration of the island.

The legislation formally incorporated both archipelagos within Vietnamese maritime boundaries. It hardened Hanoi's legal position against Chinese and other rival claims.

Pressure from lawmakers and NGOs, and encouragement from Beijing, led Taiwan to lengthen the airstrip and conduct live-fire exercises in September 2012 in which Vietnam was reportedly named the imaginary enemy. Vietnam protested the drills as a violation of its territory.

Manila renamed parts of the South China Sea and designated the Reed Bank as Recto Bank. The nomenclature asserted Philippine jurisdiction over waters it claims as its exclusive economic zone.

Chinese vessels harassed two Vietnamese oil exploration ships and opened fire on fishing boats off East London Reef and near Fiery Cross Reef; border guards in Phú Yên reported four Vietnamese vessels fired upon. The incidents triggered mass protests in Hanoi, Ho Chi Minh City and Vietnamese communities abroad.

On 18 May 2011 the state operator said its network now reached the archipelago. The announcement paralleled Beijing's wider assertion of administrative control over the disputed features.

Vietnam Military Telecommunications Corporation extended mobile telephony to its occupied features. Military-run connectivity reinforced Vietnam's administrative presence on the islands it holds.

The installation extended Philippine civilian telecommunications into the archipelago. Rival claimants followed with their own networks, using connectivity as a marker of effective administration.

A foreign ministry statement of 13 July 1999 asserted that legally, historically, geographically and in reality all of the South China Sea and Spratly Islands were under Taiwanese sovereignty, denouncing Malaysian and Philippine actions. Taipei's claim mirrors Beijing's, and the two have cooperated in international talks on the islands.

Ship number 57 was purposely run aground to establish a permanent outpost, and Filipino marines have been stationed aboard ever since. The wreck became the Philippines' principal physical foothold in the contested waters.

A routine patrol seized more than 200 kg of potassium cyanide solution used for cyanide fishing in the archipelago. The seizure highlighted destructive fishing pressure on reefs supporting nearly 3,000 recorded marine species.

The last remaining fighters of the Front de Libération du Champa laid down arms, closing decades of insurgency waged alongside Montagnard and Khmer Krom minorities. Vietnam remains wary that Champa's historical maritime role could revive minority autonomy claims within the sea dispute.

The two navies engaged in the area of Johnson South Reef, known as Gạc Ma in Vietnam and Yongshu in China. The clash entrenched Chinese footholds in the archipelago and remains a defining episode of the dispute.

Beijing installed a small facility ostensibly for oceanic observation and a tide gauge for the Global Sea Level Observing System. Following a deadly skirmish with the Vietnamese Navy, China occupied further reefs, sharply escalating tensions with Vietnam and the Philippines.

Since 1985 Brunei has claimed a continental shelf that overlaps a southern reef, and it claims an exclusive economic zone over the area, though it has made no formal claim to the reef itself.

Troops occupying Amboyna Cay shot at a vessel flying a German flag, killing one passenger; survivors escaped in a dinghy and were adrift ten days before a Japanese freighter rescued them. The incident showed how militarised even minor features had become.

Manila's EEZ claim from 1978 encompassed reefs including Johnson South, Hughes and Mischief. China later dredged sand there without charge, arguing the area constituted the waters of China's Nansha Islands, despite both states having ratified UNCLOS III.

Manila advanced its claim after Taiwanese troops on Itu Aba attacked and shot at a Philippine fishing boat. The move brought the Philippines into the dispute despite earlier American reminders that the islands lay outside the 1898 treaty limits.

A group claiming to act in the name of Morton F. Meads asserted succession to a Kingdom of Humanity supposedly founded on Meads Island between the world wars. The claim lapsed after 1972, when several members drowned in a typhoon.

China issued a declaration defining territorial waters encompassing the Spratlys, and North Vietnamese premier Phạm Văn Đồng wrote to Zhou Enlai stating the DRV respected the Chinese statement on the twelve-nautical-mile limit. After reunification Vietnam argued the note concerned only the breadth of territorial waters, but China still cites it as acquiescence.
