A new report by the U.S. Naval War College pulls together what is known about one of the world’s oddest cities. Sansha City was founded by China in 2012 and is the world’s largest city by area, covering 800,000 square miles of the South China Sea within the “nine-dash line” that China claims for itself. That makes it 1,700 times the size of New York City. Most of Sansha City is salt water, although it includes the Paracel Islands, which Vietnam and Taiwan claim, and the Spratly Islands, various of which are claimed by Vietnam, Taiwan, the Philippines, Malaysia, and Brunei.

City Hall, so to speak, is on Woody Island, one of the Paracels. “Once a remote outpost, Woody Island has become a bustling hub of activity,” says the 57-page, heavily footnoted report, which was written by China expert Zachary Haver for the War College’s China Maritime Studies Institute. “The island now boasts expanded port infrastructure, seawater desalination and sewage treatment facilities, new public housing, a functioning judicial system, 5G network coverage, a school, and regular charter flights to and from the mainland.”
