Nor did they spare its Asian allies.
US President Donald Trump appears intent on moving forward next week on US steel and aluminium tariffs with no exemptions for allies, the US commerce secretary said on Sunday (Mar 4), minimising the threat of retaliation as "pretty trivial".
Either way, the trade imbalance with Canada -America's second-largest trading partner - is nothing like the $55 billion trade deficit with Mexico, or the $385 billion deficit with China - America's largest trading partner.
In a subsequent interview on NBC's "Meet the Press", Ross allowed for the possibility that Trump may yet change his mind, as he has on other issues. Yet by raising the price of steel, those same tariffs stand to hurt a far larger group of US workers: the 6.5 million who work in industries that buy steel - from automakers to aircraft manufacturers to suppliers of building materials.
European Commission President Jean-Claude Junker said that the trade restrictions were a "blatant intervention" for the sole objective of protecting the USA industry. Of special concern to Canada is the auto industry - and how these tariffs would play havoc with cross-border supply chains.
The statement from the top Republican in the House comes as the Trump administration is arguing that the tariffs are needed to preserve American steel and aluminum and warning that North American neighbors Canada and Mexico will not get any relief unless they agree to a fair trade deal. Harley already is being hit by a deepening slump in US motorcycle demand, which has spurred job cuts and a plant closure at the Milwaukee-based company. "A stable and growing relationship will not only serve the fundamental interests of both the peoples and it is also the what the global community wants to see", Zhang, a former Chinese Ambassador to United States, said. We fight with you in every war.
He notes that while no countries will be excluded, some industries might be.
Statistics Canada has previously identified discrepancies between US and Canadian records, and attempts to explain them on its website, citing the "different data sources and statistical methods" the two countries use.
Manufacturers of metal-intensive products such as cars and airplanes already are wrestling with rising prices for steel and aluminum, in part because of tight production capacity. "But at this point in time there would be no country exclusions".
The announcement comes just less than a month after the White House revealed an infrastructure plan in which the federal government would spend just $200 billion fixing public infrastructure over the next decade and expect states, localities and private companies to generate $1.5 trillion to fund projects.
Canada exports to the USA 90 per cent of the 3.2-million tonnes of aluminum it produces annually, which represents two thirds of America's total aluminum imports.
