Japan's ambassador to Beijing is returning to Tokyo for talks on disputed islands in the East China Sea. Uichiro Niwa returned to Japan on Sunday to discuss recent Japan-China relations following an order from Foreign Minister Koichiro Gemba. Niwa told reporters at Beijing airport that consultations would center on recent developments over the islands known as Senkaku in Japanese and Diaoyutai in Chinese. Japan controls the uninhabited islands, but China and Taiwan also claim sovereignty, according to a report of the Associated Press.
