Members (R) of a Japanese nationalist group land on Uotsuri island, part of the disputed islands in the East China Sea, known as the Senkaku isles in Japan, Diaoyu islands in China, August 19, 2012. Several Japanese nationalists landed on Sunday on a rocky island in the East China Sea at the heart of a territorial row with Beijing, a move all but certain to fan anger in China and worsen ties between Asia's two biggest economies. Tokyo and Beijing have been feuding for decades over the island chain, known as the Senkaku in Japan and the Diaoyu in China, near potentially huge maritime gas fields. REUTERS/Chris Meyers (POLITICS)
