The Chinese embassy in Ottawa criticized duties slapped by Canada this week on Chinese imported steel, saying on Friday they violated World Trade Organization (WTO) rules and disrupted the global trade order.

Canada introduced limits on how much foreign steel produced in countries other than the U.S. and Mexico can be imported to help a domestic sector reeling from President Trump’s tariffs.

Canada will reduce the amount of foreign steel that importers can bring in tariff-free, a move to help domestic producers suffering from US President Donald Trump’s levies on the sector.
