Far from easing tensions, mutual recriminations heightened the temperature in choppy waters. Both sides pandered to their domestic base. Maritime incidents worsened alarmingly, ranging from the use of lasers, dangerous manoeuvres, ship collisions, and water-cannon blasting to a physical scuffle that resulted in injuries to sailors. Flashpoints flared up at the Second Thomas, Scarborough, and Sabina Shoals. Chinese vessels sighted in Philippine waters increased. Beyond the West Philippine Sea, they were also spotted in the Philippine Sea in the east and Basilan and Sibutu Straits in the south. Close calls also occurred in the sky, with People’s Liberation Army aircraft dropping flares in the path of a Philippine Air Force plane patrolling in the vicinity of Scarborough Shoal.
