In a flurry of late-April private talks, Filipino diplomats challenged officials from China over the recent pattern of assertive behaviour from Chinese vessels in the South China Sea. The behaviour by the Chinese included the early-February targeting of a Philippine Coast Guard ship with a military-grade laser near a disputed shoal and in late March a Chinese vessel purportedly came within 10 meters of a Vietnamese Fisheries Surveillance vessel while inside Vietnam’s Exclusive Economic Zone.
