Trðá»Âng Sa is an island special administrative region of Khánh Hòa province in the South Central Coast region of Vietnam. Originally, a district was established on the basis of the Spratly Islands (except Louisa Reef, Luconia Shoals and James Shoal), which is also claimed wholly or in part by Brunei, China, Malaysia, the Philippines and Taiwan. According to the 2009 census, the district has a population of 195 people.
Trðá»Âng Sa district was established on the basis of small coral islands/cays, reefs and banks of the Spratly Islands which are south east of Cam Ranh. As the islands contain a large number of scattered geographic entities, the district is divided into eight clusters including Song Tá»Â, Thá» Tứ, Loại Ta, Nam Yết, Sinh Tá»Ân, Trðá»Âng Sa, Thám Hiá»Âm and Bình Nguyên by Vietnam. On June 16th, 2025, through Resolution No. 1667/NQ of the Standing Committee of the National Assembly, Trðá»Âng Sa district was changed into a special administrative region.
According to Decree No. 65/2007/NÃÂ-CP of 11 April 2007 issued by the Government of the Socialist Republic of Vietnam, Trðá»Âng Sa district had three administrative units including one commune-level town (Trðá»Âng Sa) and two rural communes (Song Tá» Tây and Sinh Tá»Ân).
In reality, Trðá»Âng Sa district is effectively administering only 21 islets and reefs of the Spratly Islands:
