The Gaven Reefs, also known in Mandarin and ; Burgos Reefs (Filipino; Pilipino: Mga Bahura ng Burgos|lit=Reefs of [[José Burgos|Burgos]]); Vietnamese: Đá Ga Ven and Vietnamese: Đá Lạc, is a group of two reefs in the Tizard Bank of the Spratly Islands in the South China Sea.
They are occupied and controlled by China (PRC) as part of Sansha, and claimed by Taiwan (ROC), the Philippines and Vietnam. They have a supply platform and a reef fortress.
The northern reef (Nánxūn Jiāo) comprises 86ha and its highest point is 1.9abbr=offNaNabbr=off above sea level. The southern reef (Xīnán Jiāo) comprises 67ha.[1] Since 2014, north reef has been subject to significant reclamation activities.
On 12 July 2016, the tribunal of the Permanent Court of Arbitration concluded that for purposes of Article 121(3) of the Convention, the high-tide features at Gaven Reef (North) are rocks that cannot sustain human habitation or economic life of their own and accordingly shall be entitled to 12 nm of territorial sea measured from its baseline but have no exclusive economic zone or continental shelf.[2] PCA also concluded that the features at Gaven Reef (South) are, or in their natural condition were, exposed at low tide and submerged at high tide and are, accordingly low-tide elevations that do not generate entitlement to a territorial sea, exclusive economic zone or continental shelf.[2]
The supply platform at the reef has anti-aircraft guns, naval guns, search radars and radio communications equipment,[3] and reclamation work during 2014–15 expanded its area to .[4]
In late 2016, photographs emerged which suggested that Hughes Reef has been armed with anti-aircraft weapons and a CIWS missile-defence system.[5]
