China ships sail near disputed isles after Mattis visit: Japan

Japan said Chinese coast guard vessels sailed Monday into its territorial waters around disputed islands in the East China Sea, days after the new US defence chief vowed to defend Tokyo's control of them. Three ships entered the waters surrounding the uninhabited chain, the Japan Coast Guard said in a statement. The isles are controlled by Japan as the Senkakus but claimed by China as the Diaoyus.
