The People’s Liberation Army Southern Theater Command announced the exercise on its WeChat account, stating it aimed to test and enhance combat capabilities in safeguarding China’s territorial sovereignty and maritime rights and interests. The China Coast Guard separately said the drills focused on maritime rights-protection, law enforcement, and management and control around Scarborough Shoal.
Scarborough Shoal, a triangular atoll about 200 kilometers west of Luzon Island and 874 kilometers from China’s Hainan Island, has been a persistent flashpoint between Beijing and Manila. China has controlled the shoal since a 2012 stand-off that ended with Chinese occupation despite a mutual withdrawal agreement. Since then, China Coast Guard vessels have surrounded the shoal and repeatedly restricted Filipino fishermen from accessing the rich fishing grounds inside the atoll’s lagoon.
The exercise comes amid an apparent breakdown of the “provisional understanding” between Beijing and Manila over the Philippine resupply of Second Thomas Shoal, where Manila accused the China Coast Guard of obstructing a resupply mission to its troops two days earlier. The Chinese military did not specify which countries prompted the drill, but analysts note the timing closely follows the confrontation at Second Thomas Shoal.
