China builds 600-hectare atoll in Paracels

China has begun construction of a 600-hectare artificial island on Antelope Reef in the Paracel Islands, according to satellite imagery and reports. The project significantly expands China's footprint in the disputed South China Sea, raising concerns among regional neighbors and the United States. The new island is part of China's ongoing militarization efforts in the area, including airstrips and naval facilities. The construction comes amid heightened tensions over maritime claims and freedom of navigation in the region.
