Japan said on Monday that a Chinese naval submarine spotted in waters off flashpoint islands in the East China Sea was one of its new type of nuclear-powered attack vessels.
Earlier, China said three of its “Coast Guard vessels conducted a patrol in waters off the Diaoyu Islands,” Beijing’s name for the contested isles called Senkaku in Japan. Japanese Navy protested last Thursday after it spotted Jiangkai II class frigate and an unidentified submarine in disputed waters.
