“On March 9, two Chinese Coast Guard cutters blocked two Philippine transport vessels carrying supplies to marines assigned to a corroding World War II-era vessel marooned on the Ayungin Shoal, known as the Renai Shoal to China. A few days later, the Philippine military was able to resupply the unit by dropping provisions from a fixed-wing BN-2 Islander light utility aircraft, and now is vowing to send resupply vessels to challenge the Chinese Coast Guard blockade, a Philippine Navy official said.”
