Reinforcements headed to Pacific

The U.S. Navy has sent two advanced P-8A Poseidon patrol aircraft to Japan. U.S. military officials say their jobs will be to improve U.S. capability to hunt submarines and other vessels in waters near China as tension in the region mounts. Last month China established an air defense identification zone covering islands in the East China Sea controlled by Japan and claimed by Beijing. In a few days four more of the aircraft will arrive.
