With international attention this year diverted by North Korea, China has been quietly making geopolitical gains further south. Throughout 2017, Beijing has been equipping its artificial islands in the contested waters of the South China Sea for potential military use.
Aerial photos published by the Center for Strategic and International Studies in Washington show new construction on islands built by China, which now bristle with bunkers, aircraft hangars and shelters for radar, aircraft, warships and artillery.
The new infrastructure leaves China in a position to station fighter jets and warships on the outcrops in 2018, and to make ambitious claims to territorial waters and airspace around them if Beijing chooses, say analysts.
