Seize the Moment: The Evolving Landscape of the South China Sea

Antelope Reef, a diminutive, teardrop-shaped landmass in the northwestern reaches of the South China Sea, has undergone a radical metamorphosis. Until recently, this feature was barely visible, largely submerged beneath turquoise waters. However, within a mere six months, it has been transformed into a substantial 6-square-kilometer (2.3-square-mile) crescent of bright white sand, dotted with structures in one corner. This rapid expansion was achieved by dredging millions of tonnes of seabed material. Inside the lagoon encircled by this new land, numerous vessels are visible, likely cutter suction dredgers. China possesses the world’s largest fleet of these machines, with some capable of excavating 6,000 cubic meters of sediment per hour—enough to fill two Olympic-sized swimming pools. The sheer velocity of this construction effort may well constitute a global record.

Yet, Beijing is not the sole actor in this race. After years of observing China’s land reclamation to bolster its expansive territorial assertions, Vietnam has begun reclaiming reefs it claims in the South China Sea. Other claimants, including the Philippines, are engaging in similar activities, albeit on a smaller scale.

Antelope Reef lies within the Paracel Islands, a territory contested by China, Taiwan, Vietnam, the Philippines, Malaysia, and Brunei, alongside the Spratly Islands. Historically, most of these features were submerged reefs devoid of permanent human habitation. China secured control of the Paracels in 1974 following a violent conflict with South Vietnamese forces. More recently, it converted three Spratly reefs—Mischief, Fiery Cross, and Subi—into islands large enough to host airports and military installations, using these bases to support its claim of sovereignty over nearly the entire South China Sea under its controversial nine-dash line.

Today, swarms of Chinese coastguard and maritime militia vessels patrol within this nine-dash boundary, effectively stifling challenges from other claimants. This dominance has led to several confrontations in recent years with the much smaller Philippine coastguard in overlapping claim areas. The straight shoreline of a newly formed beach at Antelope Reef hints at the construction of another military-grade runway, mirroring those at the other three reefs. However, with an established airstrip already present on nearby Woody Island and significant military bases on Hainan, such a facility might seem redundant. Instead, the move may be interpreted as a strategic signal directed at Vietnam.

Relations between Hanoi and Beijing have historically been strained by disputes over the South China Sea, known in Vietnam as the East Sea. Nevertheless, in recent years, Vietnam’s communist leadership has tempered anti-Chinese rhetoric, actively pursuing closer ties with Beijing. To Lam, the recently elected president and party general secretary, made his first state visit to China earlier this year, where both nations addressed their differences regarding the Paracels and Spratlys with unusually conciliatory language. While Vietnam has formally protested China’s activities at Antelope Reef, it did so using restrained diplomatic language.

In contrast to its diplomatic caution, Vietnam has embarked on an aggressive dredging campaign in disputed areas, utilizing the same powerful cutter suction ships as China. "If you can't beat them, join them," seems to be the prevailing strategy. Over the last three years, Vietnam has pumped sand across at least 20 reefs and, according to the Washington-based Asian Maritime Transparency Initiative, has established 11 new harbors. It now controls over 11 square kilometers of reclaimed land, roughly half the area managed by China, and is beginning to install military-grade infrastructure such as navigation beacons.

"The Vietnamese have been less willing to be at the forefront of the public relations battle over their disagreements with China," says an observer noting this strategic shift.
