Because Sansha's jurisdiction comprises island groups that several nations besides the PRC claim as their own, the "city" is considered by some as controversial. In 2007, the Foreign Ministry of
Vietnam protested against the city's proposed establishment, which had been recently approved by the PRC's State Council, as Vietnam claims two of the three island groups that comprise Sansha. This was later followed by student demonstrations at the Chinese embassy in
Hanoi, and at a consulate in
Ho Chi Minh City. Days prior to the official establishment of the city in late July 2012, The United States Department of State also weighed in on the issue stating, "we remain concerned should there be any unilateral moves of this kind that would seem to prejudge an issue." The chair of the US Senate Foreign Relations East Asian and Pacific Affairs Subcommittee,
Jim Webb, also made a statement regarding Sansha and questioned whether the city's creation was a violation of international law. While Senator Webb stated that the establishment of Sansha was China "creating a governmental system out of nothing", Before these island groups were under the nominal administration of Sansha, they were nominally administered by an administrative office under the provincial government of
Hainan. where about 1,000 Chinese (PRC) reside. With a land area of 210ha, Woody Island is the largest contiguous land area in the
South China Sea. The total land area of Sansha, which includes the islands in the Paracel and Spratly groups, is less than . Nationally, Sansha is the smallest prefecture-level city, by both population and land area, but the largest by total area, and is also the southernmost prefecture-level city of the PRC. By January 2016, work was well advanced on developing a military base with a large harbour and a runway, with the reclaimed land covering . A civilian test flight to the runway was conducted by a China Southern Airlines passenger jet on 13 July 2016. On 16 February 2016, the New York Times reported that China had deployed
HQ‑9 surface‑to‑air missiles on the island. In late 2016, photographs emerged which suggested that Mischief Reef was armed with anti-aircraft weapons and a
CIWS missile-defence system. In May 2018, the
Centre for Strategic and International Studies, a US think tank, said satellite images showed China had deployed new military weapon platforms to Woody Island, the largest of the Paracels. ==See also==
