China’s commerce ministry opened a probe into optical-fiber products, investigating claims that U.S. makers of some types of fiber violated China’s antidumping measures. The investigation is part of a blizzard of actions announced by Beijing on Tuesday that target U.S. companies, after China was hit with additional levies.
Those products have been subject to antidumping tariffs since 2011, the ministry said. Such measures are designed to stop countries dumping excess production in overseas markets, pushing down prices and hurting competitors.
The investigation follows a complaint by a Chinese company. The ministry didn’t give any detail on the exact infraction or identify the U.S. companies involved. Chinese state media said this was Beijing’s first probe of suspected antidumping violations.
