National Economic Council director Kevin Hassett said in an interview with ABC News' "This Week" that the tariffs are not meant to start a trade war. "What happened was that we launched a drug war, not a trade war, and it was part of the negotiation to get Canada and Mexico to stop shipping fentanyl across our borders," Hassett said.

President Donald Trump announced the possibility of imposing new tariffs on Canadian lumber and dairy products. According to CNN Business, Trump accused Canada of unfair trade practices, pointing to a 250% tariff on American dairy products.

President Donald Trump is once again postponing aggressive new tariffs that went into effect on March 4. Trump, however, isn't canceling the tariffs — only delaying them — and in April, new 25% tariffs on goods imported into the United States from Canada and Mexico are scheduled to go back into effect.
