WASHINGTON—The U.S. Supreme Court sided against China on June 14, throwing out a lower court ruling that had allowed two Chinese vitamin C makers to escape almost $148 million in damages for violating American antitrust law.
In a case that brought trade conflicts between the world’s two largest economies before the top U.S. court, the justices ruled 9-0 that the lower court gave too much deference to Chinese government filings explaining China’s regulatory policy.
