ABOARD THE USS CARL VINSON—Japan led an annual multinational naval exercise that included the Philippines as an observer for the first time, as Filipino coast guard vessels are increasingly harassed by China in the disputed South China Sea.
The Annualex exercises that began Saturday off Japan’s coast also included the United States, Australia, and Canada. Their aim is to demonstrate and increase ways the navies can work together, and show their presence and commitment to defend a “free and open” Indo-Pacific, which the allies say is hampered by China’s growing ambitions that include sweeping territorial claims.
