The Philippine Coast Guard (PCG) reported that two Chinese coast guard vessels had followed and obstructed its ships during a support mission in the disputed South China Sea on June 30. PCG spokesperson Jay Tarriela stated on Twitter that the Chinese ships constantly followed and came within 100 yards of the PCG vessels. The incident occurred while the PCG ships were assisting a naval operation in the Ayungin Shoal. Additionally, the PCG detected six Chinese maritime militia vessels and two Chinese naval ships in the area that day. Despite the Chinese vessels’ behavior, the PCG ships were able to complete their mission safely. This incident is particularly concerning as the Philippine Navy’s operation was humanitarian in nature. The Ayungin Shoal, also known as the Second Thomas Shoal, is part of the Spratly Islands and falls within the Philippines’ exclusive economic zone (EEZ). China, however, claims much of the South China Sea under its nine-dash line. The Philippines, along with Vietnam, Malaysia, Taiwan, and Brunei, has disputed China’s claims in the area. The South China Sea is considered a “hotbed of gray zone activity” where China can act without public accountability. The PCG has been releasing photos and videos of incidents to shed light on China’s behavior in this gray zone. In recent months, the Chinese regime has exhibited more aggressive behavior in the South China Sea. In February, a Chinese coast guard vessel used a “military-grade laser” against a PCG ship. The Philippines and the United States agreed to restart joint maritime patrols in the disputed sea to strengthen their ties and defense capabilities.
