Vietnam does not control any of the islands it claims and the entire Paracel Islands is under the administration of the People's Republic of China as part of Sansha prefecture.
Vietnam established Hoàng Sa district in 1982 as part of Quang Nam-Da Nang province. Since Quảng Nam and Da Nang were split in November 1996, the island district has belonged to Da Nang.
