Japan warns China of action If territory violated

Japan warned Beijing of consequences if a Chinese naval vessel sailing near the disputed Senkaku Islands in the East China Sea intruded into Japanese territorial waters around the islets earlier this month, government sources said Saturday. 
The warning, conveyed by then Japan's Vice Foreign Minister Akitaka Saiki to Chinese Ambassador Cheng Yonghua on June 9, is thought to have related to the possible mobilization of Maritime Self-Defense Force vessels for maritime security operations, according to Japan's News Agency (Kyodo). 
Such operations can be ordered by the defense minister to respond to situations deemed difficult for the Japan Coast Guard to cope with. The use of arms is permitted, although conditionally.
