China has 20 outposts in the Paracel Islands and 7 in the Spratlys. It also controls Scarborough Shoal, which it seized in 2012, via a constant coast guard presence, though it has not built any facilities on the feature. Since 2013, China has engaged in unprecedented dredging and artificial island-building in the Spratlys, creating 3,200 acres of new land, along with a substantial expansion of its presence in the Paracels.
