A Japan Coast Guard patrol ship sails around Uotsuri island, part of the disputed islands in the East China Sea, known as the Senkaku isles in Japan, Diaoyu islands in China, in this Kyodo September 12, 2012 file photo. Japan made an official protest to China on December 13, 2012 after a Chinese government plane entered what Japan considers its airspace over disputed islets in the East China Sea, the Foreign Ministry said in Tokyo. The incident prompted Japan's military to scramble eight F-15 fighter jets, the Defence Ministry said. Mandatory Credit.
