Tensions over South Sea disputes have escalated as a Chinese Maritime Militia ship blocked a Philippine Coast Guard vessel, the BRP Datu Sanday, during a resupply mission for local fishermen near the Bajo de Masinloc. Despite the blockade, the Filipino ship was able to deliver the supplies. This incident follows a similar one in February where Chinese military vessels interfered with a Manila Coast Guard patrol. In response, the US has mobilized aircraft for joint patrols in the region, showing support for the Philippines.
