Trump said he would talk with the leaders of Canada and Mexico, which have announced retaliatory tariffs of their own, but downplayed expectations that they would change his mind.

Amid warnings of price increases, Canada moved quickly to retaliate, China said it had planned countermeasures and Mexico said it would soon unveil its response.

Canada and Mexico ordered retaliatory tariffs on American goods in response to sweeping tariffs imposed by President Donald Trump, and businesses and consumers in both countries questioned Sunday how the new trade war might affect them.
