China will co-operate with its co-complainants to enforce a World Trade Organisation (WTO) panel’s judgement that US steel duties violate global trade rules. The WTO Appellate Body for trade disputes has ruled that the emergency tariffs imposed by the USA on steel imports were in breach of WTO rules. China, along with seven co-complainants, including the European Union, Japan, the Republic of Korea, Switzerland, Norway, New Zealand and Brazil, welcomed the panel’s ruling and called upon the USA to “terminate its WTO incompatible safeguard measures without delay.”
