New satellite images indicate that China's land reclamation efforts at Antelope Reef in the South China Sea are nearing completion. Researchers from the Open Source Centre (OSC) observed that dredgers within the reef's lagoon were replaced by cargo barges in an image taken on June 22, suggesting the reclamation phase is almost finished.

Researchers from the Open Source Centre (OSC) observed that dredgers within the reef's lagoon were replaced by cargo barges in an image taken on June 22, suggesting the reclamation phase is almost finished. Further images from June 24 revealed the appearance of four large storage silos at a concrete production plant on the reef, which researchers interpret as a potential shift towards heavy infrastructure construction. These developments point to China's ongoing activities in the Paracel Islands.
