According to the Reuters news service, China contends the tariffs will "disrupt and distort global industrial and supply chain[s]."

Canada on Tuesday published the final list of steel and aluminum products that will be subjected to the 25% tariff. 

“We are moving in lockstep with key international partners to protect Canadian workers and businesses in our steel and aluminum sectors from China’s intentional, state-directed policy of overcapacity and oversupply, which is undermining Canada’s ability to compete in domestic and global markets," said Chrystia Freeland, Canada’s deputy prime minister and minister of finance. 

"Canada is taking decisive action to level the playing field and protect Canadian workers and investments in Canadian industry."

The United Steelworkers union in Canada is applauding the action, saying it will strengthen Canada's economy and labor market and protect manufacturing jobs.

“This isn't about creating barriers; it's about giving Canadian workers a chance to defend their jobs against unfair trade practices that have hurt our industries for far too long,” the USW said. “While some Canadian companies may be reluctant, the overall picture is clear: this is a step toward saving good jobs and building stronger domestic industries.”
