The Rapid Rise of Antelope Reef: A New Reality in the South China Sea


For the first time since the 1970s, Antelope Reef – a tiny, mostly submerged point in the Paracel Islands – has been turned into a 6‑square‑kilometre island of gleaming white sand. The transformation happened in just six months, thanks to the relentless work of cutter‑suction dredgers that China operates in record numbers.


At the heart of each dredger is a massive scoop capable of extracting 6,000 cubic metres of sediment per hour, a volume that could fill two Olympic‑sized swimming pools. The dredging moved millions of tonnes of sea‑bed sand to the surface, creating a crescent-shaped land mass that now hosts a handful of buildings and a lagoon filled with more ships, including the very dredgers themselves.


China’s rapid reclamation at Antelope Reef is part of a broader strategy that has seen the country turn three Spratly reefs – Mischief, Fiery Cross and Subi – into islands capable of hosting airstrips and military bases. In doing so, China has claimed vast stretches of the South China Sea within its infamous nine‑dash line, a claim that has sparked fierce disputes with several neighbouring states.


A Dredging War


Vietnam, once a battlefield for Chinese forces, has begun to mirror the scourge by dredging at least twenty reefs over the past three years. According to the Asian Maritime Transparency Initiative, Vietnam has opened 11 new harbours and cultivated over 11 square kilometres of reclaimed land – roughly half of what China controls. Military‑grade infrastructure such as navigation beacons is already appearing, signalling a strategic shift: If you can’t beat us, join us.


The Political Landscape


While Vietnam has softened its rhetoric toward Beijing, it still protests Chinese construction diplomatically. Yet the Vietnamese are actively expanding their own military footprints, especially at the disputed Spratlys. The Philippines has backed these moves with U.S. support, conducting Freedom of Navigation Operations and receiving significant military aid.


The United Nations’ Permanent Court of Arbitration ruled in 2016 that China’s nine‑dash line claims lack historical basis and that its island‑building contravenes international law – a verdict China has largely ignored. As result, the Philippines and Vietnam continue to act unilaterally, while ASEAN’s attempts to formalise a code of conduct have stalled.


In this new environment, there is no binding agreement to stop the construction. The South China Sea has become essentially a one‑country‑for‑itself contest, with China leading the charge, Vietnam following, the Philippines balancing with U.S. backing, and other claimants gradually building out from the sidelines.
