A Chinese marine surveillance ship Haijian No. 66 (C) cruises next to Japan Coast Guard patrol ships in the East China Sea, in this aerial file photo provided by Kyodo and taken September 24, 2012. A long-simmering row over the East China Sea islands, known as the Senkaku in Japan and the Diaoyu in China, has in recent months escalated to the point where both have scrambled fighter jets while patrol ships shadow each other in nearby seas.
