A Japanese surveillance plane and about 20 troops conducted the first of two days of joint training with the Philippine navy on Tuesday off the coast of Palawan, a strategically important island not far from contested islands claimed by several countries including China and the Philippines.
While the P-3C plane was being used for maritime search-and-rescue drills and disaster relief drills, the aircraft is also a mainstay of Japan's anti-submarine and other aerial surveillance efforts. In theory, it could help the U.S. keep an eye on the Chinese navy in the South China Sea.
