Beijing Constructing Military Infrastructure on Small South China Sea Island: Satellite Imagery Reveals

New construction activity has been spotted on a minor islet near the Antelope Reef in the Paracel Islands of the South China Sea, according to satellite imagery reviewed by Reuters. Security analysts suggest that Beijing is steadily expanding its military footprint and strategic capabilities in this heavily contested and vital maritime corridor.

Commercial satellite provider 'Vantor' captured images showing that construction began around March and April, with the latest imagery from August 17 revealing a distinct three-branched structure. While the exact purpose of the structures on Yagong Island remains unconfirmed, analysts indicate they closely resemble radar or early-warning facilities seen elsewhere in the region, likely serving as a support system for primary military operations on the nearby Antelope Reef.

This development follows previous reports detailing the completion of China's first phase of construction on Antelope Reef, which features an artificial island roughly 6 kilometers long with a straight coastline exceeding 3 kilometers—prompting speculation about a potential runway. Beijing has consistently denied building military outposts, claiming through state media that the infrastructure is intended for civilian purposes such as weather forecasting, marine environmental protection, and scientific research.

China has occupied the Paracel archipelago since seizing it from South Vietnam in 1974. Analysts note that these ongoing fortifications significantly strengthen Beijing's strategic dominance over the northern section of the vital trade route, raising tensions among rival claimants including Vietnam, the Philippines, Malaysia, Taiwan, and Brunei, particularly in light of broader regional security dynamics surrounding Taiwan.
