NextFin News - A dramatic acceleration in land reclamation across the South China Sea has entered a new, more competitive phase as regional claimants shift from diplomatic protest to physical expansion. At the center of this shift is Antelope Reef, a teardrop-shaped feature in the Paracel Islands that has been transformed from a submerged hazard into a 6-square-kilometer island in just six months. The speed of the operation, involving massive cutter suction dredgers capable of moving 6,000 cubic meters of sand per hour, underscores a "grab what you can" mentality that is redefining the geopolitical landscape of the world’s most contested waterway.
The activity at Antelope Reef is widely seen as a strategic signal from Beijing. While China already maintains a significant military presence on nearby Woody Island, the construction of what appears to be a military-grade runway on Antelope Reef suggests a desire to reinforce its dominance in the Paracels. This move comes despite a recent period of relative diplomatic calm between Beijing and Hanoi. U.S. President Trump’s administration has continued to monitor these developments closely, as the South China Sea remains a critical artery for global trade and a flashpoint for maritime security.
Vietnam has emerged as the most active counter-player in this "dredging war." Over the past three years, Hanoi has expanded at least 20 reefs under its control, creating 11 new harbors and reclaiming more than 11 square kilometers of land. According to Greg Poling, director of the Asian Maritime Transparency Initiative (AMTI), Vietnam has adopted a "join them if you can’t beat them" strategy. Poling, who has long tracked maritime security in the region, notes that while Vietnam avoids the public-relations-heavy approach favored by the Philippines, it has shown a significant willingness to physically defend its holdings and expand its infrastructure on the water.
This assessment of Vietnam’s strategy is echoed by Ray Powell, director of Sealight at Stanford University. Powell suggests that China’s rapid work at Antelope Reef is a direct response to Vietnam’s recent gains. While Beijing has been preoccupied with high-profile standoffs against the Philippines at Second Thomas Shoal, Vietnam has quietly utilized that distraction to fortify its own positions. The reclamation at Antelope Reef serves as a reminder of China’s superior industrial capacity and its intent to maintain its status as the primary power in the region.
The Philippines, meanwhile, is pursuing a different path, combining modest infrastructure upgrades with international legal and military alliances. Manila is currently expanding the runway at Thitu Island and reinforcing the BRP Sierra Madre, a grounded vessel serving as a military outpost. However, the balance of power remains heavily skewed. Despite a 2016 ruling by the Permanent Court of Arbitration in The Hague that invalidated China’s "nine-dash line" claims, Beijing has continued to deploy coastguard and maritime militia swarms to overwhelm smaller neighbors.
The failure of the Association of Southeast Asian Nations (ASEAN) to secure a legally binding Code of Conduct after three decades of negotiations has led to a fragmentation of the regional response. Analysts like Poling suggest that the "new reality" involves individual nations pursuing their own interests independently of the stalled ASEAN process. This shift toward unilateral fortification and bilateral negotiations among smaller claimants marks a departure from the multilateral ideals of the past decade, as each state accepts that China’s presence is a permanent and dominant fixture of the maritime environment.
