Taiwan's Mainland Affairs Council on Friday called China's traffic control order "ridiculous" and a trampling of international norms. The order, issued Wednesday via Chinese state media, required northbound vessels entering the Taiwan Strait from Thursday night to follow routing instructions and shelter from Typhoon Dolphin. Taiwan's Coast Guard reported no abnormal Chinese vessel movements and no shipping companies had complained of broadcast interference. It instructed merchant ships to disregard any Chinese demands and to report incidents immediately. The typhoon is tracking north of Taiwan and expected to make landfall on China's east coast late Saturday or early Sunday.
