Trump and his allies argue that America's trading partners - especially China - are taking advantage of the USA and that the tariffs will cause American companies to make more steel and aluminum here, creating jobs and boosting the economy. "Canada is a secure supplier of aluminum and steel to the U.S. defense industry, putting aluminum in American planes and steel in American tanks".
FILE - U.S. President Donald Trump is after signing a proclamation to establish tariffs on imports of steel and aluminum at the White House in Washington, U.S., March 8, 2018. He estimated the USA tariffs would affect $4 billion in trade between the two countries.
The US administration also launched a national security investigation last week into vehicle and truck imports, using the same 1962 law it has applied to curb incoming steel and aluminum.
As for the U.S.'s national security argument, Fox said, "In the case of the United Kingdom, we send steel to the USA that is vital to their defence industry; it is patently absurd".
President Donald Trump had originally imposed the tariffs in March, saying a reliance on imported metals threatened national security.
Meanwhile, Canada - the largest supplier of steel to the USA - has announced tariffs on U.S. imports of metals and other products such as whisky and orange juice.
"The United States has been taken advantage of for many decades on trade".
"This is (going to have) significant consequences", Qualtrough said on the sidelines of the trade show after a breakfast address in which she provided an update on several major military procurement projects.
European Union trade chief Cecilia Malmstrom says the bloc is taking China to the World Trade Organization over a dispute on intellectual property.
Canadian Foreign Minister Chrystia Freeland had traveled to Washington on Tuesday to discuss the issue, among other matters, with U.S. Trade Representative Robert Lighthizer.
A Commerce Department investigation earlier this year determined a need to ensure adequate USA steel production capacity to supply the military. "This is a very strong Canadian action in response to a very bad USA decision". Brazil, Argentina and Australia reached what Mr. Trump called "satisfactory" deals to head off tariffs, but Canada, Mexico and the European Union apparently fell short.
Jean-Claude Juncker, president of the European Commission, said the bloc would move ahead with tariffs that are expected to affect roughly $7.5 billion worth of United States exports.
The Mexican measures target pork legs, apples, grapes and cheeses as well as steel - products from US heartland states that supported Trump in the 2016 election. That in itself would be nothing new, but the targets of these tariffs were what made Trump's announcement surprising. A handful of other USA trading partners, including South Korea, Australia, Argentina and Brazil, previously won permanent exemptions by agreeing to quotas on their exports. Macron pledged the riposte would be "firm" and "proportionate" and in line with World Trade Organization rules.
"President Trump is mainly hurting the American steel industry and consumers by driving up prices".
