China Completes 6-km Antelope Reef Island as Analysts Eye Major South China Sea Base

Q: While the world watches China's island-building, which neighboring nation is quietly accelerating its own massive military dredging race in the region?

Vietnam. While attention is fixed on China’s rapid buildout at Antelope Reef in the Paracels, Vietnam is quietly carrying out the region’s second-largest dredging and reclamation campaign in the disputed Spratly Islands. Satellite analysis cited in the background material says Hanoi is expanding military and maritime infrastructure at 27 sites across at least 18 reefs. That work includes new harbors, communications facilities and a major runway project at Barque Canada Reef that could reach about 13,000 feet. Analysts say the goal is to improve Vietnam’s logistics, air and maritime surveillance, and its ability to sustain forces on occupied features and deter Chinese pressure around fishing, oil and gas operations. Even so, experts also stress that Vietnam is not close to matching China’s overall military advantage. China still holds far more reclaimed land, more advanced airstrips and ports, and much greater naval, coast guard and militia capacity. But in practical terms, Vietnam is the neighboring state most actively accelerating its own military dredging race in response to China’s island-building.

Satellite images show China has finished the first reclamation phase at Antelope Reef after at least six months, creating an artificial island nearly 6 km long in the disputed Paracel Islands.
A 680-metre wharf, deep-water harbour, new buildings and a helicopter pad are already visible, while CSIS said initial excavation for a possible runway appears to have begun.
China says the project serves civilian uses such as weather forecasting and scientific research, but regional analysts say the infrastructure could significantly expand Beijing’s military reach in the northern South China Sea.
Antelope Reef’s location near the mainland and existing Paracel facilities could help China monitor surrounding waters, support Taiwan-related operations and complicate U.S. and allied activity in any future conflict.
The buildout also sharpens pressure on Vietnam, which claims the Paracels, and reinforces a broader Chinese network of ports, airfields and surveillance outposts across the South China Sea.

Antelope Reef Transformed: China’s 1,490-Acre Island-Building Surge in the Paracels and the Escalating South China Sea Crisis (2025–2026)

Overview

China’s sudden large-scale dredging at Antelope Reef in late 2025 triggered rising regional tensions by early 2026, catching neighboring countries off guard. This rapid expansion was partly a response to Vietnam’s own island-building efforts, as Beijing aimed to maintain dominance. The construction caused severe ecological damage by burying coral reefs, while China’s fleet evaded international scrutiny by turning off tracking systems. As the U.S. shifted military focus elsewhere, a carrier gap emerged in the Indo-Pacific, further complicating the security landscape. With little hope for a binding regional agreement, countries like Vietnam and the Philippines began strengthening their own defenses outside ASEAN frameworks.
