US, Japan, Australia and the Philippines to stage military drills in South China Sea on Sunday (April 7)

MANILA, Philippines (AP): The United States, Japan, Australia and the Philippines will hold their first joint naval exercises, including anti-submarine warfare training, in a show of force Sunday in the South China Sea where Beijing’s aggressive actions to assert its territorial claims have caused alarm.

The four treaty allies and security partners are holding the exercises to safeguard "the rule of law that is the foundation for a peaceful and stable Indo-Pacific region” and uphold freedom of navigation and overflight, they said in a joint statement issued by their defense chiefs Saturday.
