Spratly Islands in the context of "Thitu Island"

Taiping Island, also known as Itu Aba, and various other names, is the largest of the naturally occurring Spratly Islands in the South China Sea. The island is elliptical in shape being 1.4 kilometres (0.87 mi) in length and 0.4 kilometres (0.25 mi) in width, with an area of 46 hectares (110 acres). It is located on the northern edge of the Tizard Bank (Zheng He Reefs; 鄭和群礁). The runway of the Taiping Island Airport is easily the most prominent feature on the island, running its entire length.

The island is administered by the Republic of China (Taiwan), as part of Cijin, Kaohsiung. It is also claimed by the People's Republic of China (PRC), the Philippines and Vietnam.

Kalayaan, officially the Municipality of Kalayaan (Tagalog: Bayan ng Kalayaan), is a municipality under the jurisdiction of the province of Palawan, Philippines. According to the 2024 census, it has a population of 406 people, making it the least populated town in Palawan and in the Philippines.

Part of the Spratly Islands, in the South China Sea, the Kalayaan municipality, which includes Thitu Island (locally known as Pag-asa, the administrative center of Kalayaan Island Group) is 280 nautical miles (320 mi; 520 km) northwest of Puerto Princesa and 932 kilometres (503 nmi; 579 mi) south-west of Metro Manila. It consists of a single barangay named Pag-asa located on Thitu, which also serves as the seat of the municipal government. Besides Thitu Island, the municipality comprises six other islands: West York Island, Northeast Cay, Nanshan Island, Loaita Island, Flat Island (South China Sea) and Lankiam Cay (respectively locally named Likas, Parola, Lawak, Kota, Patag and Panata), and three shoals or reefs: Irving Reef (Balagtas Reef), Second Thomas Shoal (Ayungin Shoal) and Commodore Reef (Rizal Reef). It is the least populated municipality in the Philippines. Kalayaan's annual budget is 47 million pesos (about $1.1 million).

The nine-dash line, also referred to as the eleven-dash line by Taiwan, is a set of line segments on various maps that accompanied the claims of the People's Republic of China (PRC, "Mainland China") and the Republic of China (ROC, "Taiwan") in the South China Sea.

The contested area includes the Paracel Islands, the Spratly Islands, the Pratas Island and the Vereker Banks, the Macclesfield Bank, and the Scarborough Shoal. Certain places have undergone land reclamation by the PRC, ROC, and Vietnam. The People's Daily of the PRC uses the term Duànxùxiàn (Tuan-hsü-hsien; 断续线) or Nánhǎi Duànxùxiàn (Nan-hai tuan-hsü-hsien; 南海断续线; lit. 'South Sea intermittent line'), while the ROC government uses the term Shíyīduàn xiàn (Shih-i-tuan hsien; 十一段線; lit. 'eleven-segment line').

Taiping Island Airport (Chinese: 太平島機場; pinyin: Tàipíng Dǎo Jīchǎng) is an airport on Taiping Island, Cijin District, Kaohsiung, Taiwan. It is located in the Spratly Islands of the South China Sea. The island (named Itu Aba before 1946) has been stationed by the Republic of China (Taiwan) with military personnel since 1956.

Brunei, Indonesia, Malaysia, the Philippines, the People's Republic of China (PRC), Taiwan (Republic of China/ROC), and Vietnam have conflicting island and maritime claims in the South China Sea. The disputes involve the islands, reefs, banks, and other features of the region, including the Spratly Islands, Paracel Islands, Scarborough Shoal, and various boundaries in the Gulf of Tonkin. The waters near the Indonesian Natuna Islands, which some regard as geographically part of the South China Sea, are disputed as well.

An estimated US$3.36 trillion worth of global trade passes through the South China Sea annually, which accounts for a third of the global maritime trade. 80 percent of China's energy imports and 40 percent of China's total trade passes through the South China Sea. Claimant states are interested in retaining or acquiring the rights to fishing stocks, the exploration and potential exploitation of crude oil and natural gas in the seabed of various parts of the South China Sea, and the strategic control of important shipping lanes. Maritime security is also an issue, as the ongoing disputes present challenges for shipping.
