China and the United States exchanged sharp criticism at a World Trade Organization meeting on Friday, with Beijing calling Washington a "unilateral bully" and the U.S. accusing its rival of illegal retaliatory measures.
China's ambassador to the WTO Li Chenggang spoke at a meeting on trade disputes shortly after the United States lodged an appeal against a series of WTO rulings involving China, Turkey, Norway and Switzerland which found that U.S. metal tariffs breached global rules.
