China has intensified its military activities in the South China Sea, restricting access to key areas while expanding its infrastructure on disputed islands, according to regional analysts and satellite imagery reviewed by multiple outlets. The moves come amid escalating tensions with neighboring countries and the United States over maritime sovereignty claims.
The People’s Liberation Army Navy (PLAN) has reportedly established new exclusion zones around the Paracel and Spratly Islands, limiting foreign vessels and aircraft. Satellite images show recent construction of radar installations and airstrips on several artificial islands. “China is methodically turning these reefs into unsinkable aircraft carriers,” said a regional security analyst speaking on condition of anonymity.
The South China Sea serves as a crucial shipping lane carrying over $3 trillion in annual trade. China claims historical rights to nearly 90% of the waters, conflicting with claims by Vietnam, Philippines, Malaysia, Brunei and Taiwan. In 2016, an international tribunal rejected Beijing’s sweeping claims under UNCLOS, though China has ignored the ruling.
U.S. Indo-Pacific Command has increased freedom of navigation operations (FONOPs) in response. “We’re seeing the most aggressive Chinese posture since the 2014 oil rig standoff with Vietnam,” noted a State Department official. Observers warn the moves could presage a potential ADIZ declaration over the contested waters.
