Japanese and Chinese foreign ministers met late Tuesday in New York to discuss the disputed islands in the East China Sea. Called Senkaku in Japan and Diaoyu in China, the islands were purchased by Japan this month. The row is hurting trade between Asia's two biggest economies and tensions are mounting. Earlier on Tuesday, vice foreign ministers met in Beijing. In the New York meeting, on the sidelines of the UN General Assembly, Japan's Koichiro Gemba called the mood "severe" and urged restraint, while China's Yang Jiechi called Japan's purchase a "gross violation of China's territorial integrity and sovereignty."
