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 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.
