China has significantly expanded its presence in the disputed Antelope Reef area of the South China Sea, with new satellite imagery revealing the construction of a large artificial island, complete with a deepwater harbour, runway, wharf, and helipad. Analysts say the development marks one of Beijing’s most ambitious projects in the region and could reshape the strategic balance in the contested waters.
The artificial island, reviewed through imagery analysed by Reuters, stretches 6 kilometres, including a 3‑kilometre straight section believed to be a runway capable of accommodating fighter jets and military transport aircraft. Experts say the scale of construction suggests China intends to use Antelope Reef as a major military and logistical hub.
Antelope Reef lies within the Paracel Islands, a cluster controlled by China since the 1970s but also claimed by Vietnam. The Paracels form part of the wider South China Sea dispute, where China asserts claims over waters surrounding nearly every neighbouring maritime nation — leading to overlapping territorial tensions with Vietnam, the Philippines, Malaysia, Brunei, and Indonesia.
Strategically, the Paracels hold heightened importance in any potential conflict involving Taiwan. According to Ben Lewis, founder of the open‑source intelligence platform PLATracker, Antelope Reef could become one of China’s most important military installations, surpassing Woody Island in scale and offering easier defence compared to China’s more dispersed bases in the Spratly Islands.
Lewis added that the South China Sea and China’s Southern Theater Command have gained elevated priority within the Central Military Commission, particularly in relation to Taiwan.
