From before the 1870s the island was used by fishermen from
Hainan. They had a semi-permanent settlement. Supplies were shipped from Hainan to the island in exchange for turtle shells. China first asserted sovereignty in the modern sense to the South China Sea island when it formally objected to France's efforts to incorporate Itu Aba and other islands and rocks into
French Indochina during the 1884–1885
Sino-French war. The French conceded the
Paracels and Spratly Islands to the
Qing government, in exchange for recognition of Vietnam as a French territory. Sensing the weaknesses of the
Republic of China, France formally incorporated the Paracel and Spratly islands into French Indochina in 1932, a year after the Japanese formally invaded northeast China (
Manchuria). China and Japan both protested. On 6 April 1933, France seized the Spratlys, formally included them in French Indochina, and built a couple of weather stations on them, but did not disturb the numerous Chinese fishermen it found there. On 3 July 1938, On 3 October 1946, China's leader Chiang Kai-Shek ordered the Navy to send a force to take control of the South China Sea islands: this force left Shanghai on 29 October, arriving at Itu Aba on one and a half months later, after stopping at the Paracel Islands. This expedition was assisted with US naval logistical support. The other three ships likewise had their names used: Woody Island (in the Paracels) was named
Yongxing (Yung-hsing) Island (presently PRC-occupied), Triton Island (Paracels) was named
Zhongjian (Chung-chien) Island (presently PRC-occupied), and Thitu Island (Spratlys) was named
Zhongye (Chung-Yeh) Island (presently Philippines-occupied). Imperial Japanese forces would not depart from the archipelago until 1946. In July 1949, French naval forces reported encountering both a Chinese Nationalist and a Chinese Communist force garrisoning Itu Aba Island. After being secured by Nationalist China, the island was placed under the administration of China's
Guangdong Province. When the
Chinese Communists gained control of mainland China, the defeated Nationalists retreated to Taiwan, but retained control of the Taiping garrison. Japan officially renounced its control and transferred the island to the trusteeship of the Allied Powers within the
San Francisco Peace Treaty on September 8, 1951. A different interpretation is that Japan officially renounced its sovereignty and transferred the island to the Republic of China under the provisions of the Taipei Peace Treaty. In 1952, a Philippine civilian (Tomás Cloma) began to mine sulfur from Taiping Island after claiming it as part of Freedomland and that same year, a note attached to the
Treaty of Taipei provided the Nationalist Chinese arguments for sovereignty over the island. The Nationalists established a permanent presence on the island in July 1956. , 2001) From 2000, a detachment of the ROC
Coast Guard Administration was stationed on the island, replacing the
Marine Corps detachment. The
Taiping Island Airport was completed in December 2007, and a
C-130 Hercules transporter airplane first landed on the island on 21 January 2008. On 2 February 2008, ROC president
Chen Shui-bian personally visited the island accompanied by a significant naval force including two fleets with
Kidd class destroyer flagships and two submarines. On 19 April 2011, it was announced that the Marine Corps would once again be stationed on the island. In February 2012, the ROC began construction of an antenna tower and associated facilities with the purpose of providing navigation assistance for aircraft landing. The tower had a planned height of approximately , and was scheduled to be completed in April 2012, and fully functional after proper testing in September 2012. In July 2012, ROC authorities revealed a project which intended to extend the runway by , which would allow the island to accommodate various kinds of military aircraft. In late August 2013, the ROC government announced that it would spend US$112 million on upgrading the island's airstrip, and constructing a dock capable of allowing its 3,000-ton Coast Guard cutters to dock, due to be completed by 2016. On July 12, 2016, a tribunal of the
Permanent Court of Arbitration backed the Philippines in an
arbitration proceedings against China's "
nine-dash line" claim which includes Taiping Island controlled by Taiwan. Both China and Taiwan have strongly rejected the ruling. ==Geography==
