Sansha Yongxing Airport is a civilian-military dual-use airport located on Yongxing Island, the largest of the disputed Paracel Islands in the South China Sea. Yongxing/Woody Island is occupied and administered by China (PRC) as the seat of Sansha city of Hainan Province. The airport was expanded in 1990 to increase the combat range of Chinese warplanes. Further construction and reclamation of land commenced in 2012 to lengthen the airstrip. This work was completed in October 2014.
