South China Sea: US, Philippines, Japan, Australia to hold naval drill on Sunday amid China’s aggressive actions
- It would be the first full-scale exercise involving the countries aimed at enhancing interoperability among their forces, amid China’s aggression
- In August, the same four countries conducted joint training on offshore replenishment off the northwest Philippines

It would be the first full-scale exercise involving the four countries aimed at enhancing interoperability among their forces, the sources said. The exercise will include anti-submarine warfare training, communication drills and sailing ships in formation.
Sunday’s planned drill would occur against the backdrop of China’s assertiveness in the resource-rich South China Sea. The latest incident happened on March 23 when the Chinese Coast Guard fired a water cannon at a Philippine vessel on a mission to the Manila-controlled Second Thomas Shoal.
The vessel was heavily damaged in the incident, while Filipino servicemen aboard were injured.
The Royal Australian Navy’s frigate Warramunga arrived in Palawan for a port call ahead of the joint exercise, with Commander Jennifer Graham paying a courtesy call on the Philippine military commander in the area, a Philippine source said.
