Amid tensions in the Middle East, China is tightening its control over the South China Sea. Satellite imagery shows Chinese vessels have erected a floating barrier at the entrance to Scarborough Shoal, a disputed fishing reef within the Philippines’s exclusive economic zone. The deployment restricts Filipino access to the shoal, where Chinese coast guard and maritime militia vessels have long harassed Philippine boats and disrupted fishing activity. China’s actions move beyond routine harassment to more direct restrictions on access. They reflect a broader pattern: Beijing is using gray-zone tactics to assert operational control over contested waters while staying below the threshold for armed conflict and limiting the risk of a direct U.S. response. These incremental steps, while individually limited, cumulatively shift the status quo in Beijing’s favor without triggering a kinetic response.
