Subi Reef, also known as Zamora Reef (Filipino: Bahura ng Zamora, lit. 'Reef of Zamora'); Zhubi Reef (Mandarin Chinese: 渚碧礁; pinyin: Zhǔbì Jiāo); Vietnamese: đá Xu Bi, is an atoll in the Spratly Islands of the South China Sea located 26 km (16 mi) southwest of Philippines' Pag-asa island Thitu Island under the municipality of the Kalayaan Island Group, Palawan province as claimed by Philippines. It is occupied by China (PRC), and claimed by Taiwan (ROC) and Vietnam. According to the claims of the PRC, it currently falls under the de facto jurisdiction of Nansha islands, Sansha city, Hainan province, China. But under the clauses of the UNCLOS, which the PRC is also a signatory, the international law (if applied) only the Philippines has the maritime rights to exploit its resources or build structures, as it is within the continental shelf ("Extended Continental Shelf") of the coastal country.
