United States exports of steel and other metal products now face a 25-percent tax, while other products-such as milk, ketchup, beef, and yogurt-will be taxed at 10 percent.

Trump said in an interview that aired Sunday that he could quickly sign an agreement with the United States' neighbours, "but I'm not happy with it".
The Canadian tariffs are expected to hit industries in numerous swing states that are crucial for Republicans in the midterm elections, including Pennsylvania, Ohio, Kentucky and Florida.

"Canadians and- I'm telling you- Americans alike, don't want to see tariff escalation", he said.
On Friday Trudeau spoke with U.S. President Donald Trump by telephone, reiterating that Canada has had "no choice" but to take countermeasures against the U.S. tariffs.
"The two leaders agreed to stay in close touch on a way forward", it added.
