American importers will pay a new 25 percent tax on goods from Canada and Mexico and a 10 percent levy on products from China.

U.S. President Donald Trump has ordered sweeping tariffs on goods from Mexico, Canada and China, demanding that they curb the flow of illegal immigrants and fentanyl into the United States, kicking off a trade war that could dent global growth and stoke inflation.

Trump has said tariffs are a way to force the countries to stop the flow of migrants and fentanyl across the borders and into the U.S.

Trump’s move to impose new tariffs has bewildered the United States’ closest allies and trading partners, who have vowed to respond with levies of their own.

President Donald Trump has signed an order to impose stiff tariffs on imports from Mexico, Canada, and China, fulfilling a campaign promise but raising the prospect of increased prices for American consumers.
