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.

Ottawa this week introduced a tariff rate quota for countries with which it has free trade agreements, excluding the U.S., and imposed additional tariffs on steel imports from all countries containing steel melted and poured in China before the end of July.

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.
