FILE - In this Oct. 25, 2012 file photo, ships of China Marine Surveillance and Japan Coast Guard steam side by side near disputed islands, called Senkaku in Japan and Diaoyu in China, in the East China Sea. Chinese patrol boats have harried the Japanese Coast Guard many times a week for more than a month in an unusually relentless response to their latest maritime spat. China says ships from its Marine Surveillance service are merely defending Chinese sovereignty and protesting illegal Japanese control over the uninhabited islands, known as Senkaku in Japan and Diaoyu in China.
