FILE - In this Sept. 2, 2012 file photo, the survey ship Koyo Maru, left, chartered by Tokyo city officials, sails around Minamikojima, foreground, Kitakojima, middle right, and Uotsuri, background, the tiny islands in the East China Sea, called Senkaku in Japanese and Diaoyu in Chinese. China hastily published a map to help maintain public outrage over the Japanese government’s purchase of some of the islands from their private Japanese owners. Beijing also has engaged in another type of mapmaking that may end up escalating the conflict. It has drawn new territorial markers, or baselines, around the islands, and submitted them to the United Nations. That could lead to a more serious attempt to claim the land, and broad swaths of valuable ocean around it.
