Stars and Stripes reports that “two of the Navy’s new P-8A Poseidon reconnaissance aircraft have arrived at Kadena Air Base in Okinawa, Navy officials in Japan said Monday.”

“The P-8’s long-planned arrival in the western Pacific comes about a week after China unilaterally declared a broad swath of the East China Sea’s air space as its national air defense identification zone and demanded that military aircraft identify themselves and file flight plans with the Chinese government.”

“The United States, Japan and other Asian nations have stated that their military aircraft will not recognize the zone, which includes airspace over the Japanese-administered Senkaku islands.”
