China Accelerates Construction of a New Military Base on Antelope Reef

State-backed engineers have spent eight months building the foundations of a permanent military complex on Antelope Reef, a submerged feature in the Paracel archipelago that Vietnam also claims. High-resolution satellite images from the Colorado-based spatial intelligence firm Vantor show nearly two dozen dredgers operating through spring and early summer, pumping fill material that turned the lagoon into solid ground. By mid-July, the reef hosted a multi-pier harbor where at least one Chinese Coast Guard vessel docked in June, and a developed area on the eastern side that appears to serve as an administrative hub, according to analysis by the Asia Maritime Transparency Initiative (AMTI) at the Center for Strategic and International Studies.

China began reclamation on Antelope Reef last fall, shortly after President Donald Trump returned to the White House. The project follows a pattern of rapid land-reclamation that U.S. administrations, including Trump’s, have repeatedly criticized as an effort to formalize longstanding maritime claims. China’s state-owned construction firms have previously transformed Woody Island in the Paracels and outposts in the Spratly chain into heavily militarized sites capable of supporting fighter jets and nuclear-capable bombers. The 1982 United Nations Convention on the Law of the Sea, which China ratified in 1996, does not grant artificial islands territorial seas or exclusive economic zones, yet Beijing continues to assert such rights.

• Harbor facilities: Multi-pier port with at least one Coast Guard vessel present (Vantor).

• Planned airstrip: Researchers at AMTI estimate a runway up to 10,000 feet could be built, potentially making Antelope Reef China’s largest island base in the disputed waters.

Newsweek

• Potential defenses: Radar, anti-ship and anti-aircraft missile systems, barracks, and aircraft hangars are expected to follow, mirroring other Chinese outposts.

• Wang Yi (1995): The former foreign minister declared that facilities built above water were “completely for civilian purposes” and that “It is so right now and it will also be so in the future.”

Newsweek

• U.S. military officials: Admiral Harry Harris previously called China’s dredging effort a “great wall of sand,” while Admiral John Aquilino noted that China has already militarized at least three outposts in the Spratly group.
