China’s frantic construction activity on a series of disputed reefs in the South China Sea has set off alarm bells across the Pacific and in Washington, raising fears that Beijing is putting steel in the ground to back up its contentious claims to a big swath of one of the world’s key waterways.

Dredging vessels have been sucking out sand to create land where none was found before, and China is building new installations on the islands, including possibly airstrips, barracks, and radar sites.
