U.S. President Donald Trump said on Saturday he would impose a 100% tariff on Canada if it follows through on a trade deal with China and warned Canadian Prime Minister Mark Carney that a deal would endanger his country, Reuters reported.

"China will eat Canada alive, completely devour it, including the destruction of their businesses, social fabric, and general way of life," Trump wrote on Truth Social.

"If Canada makes a deal with China, it will immediately be hit with a 100% Tariff against all Canadian goods and products coming into the U.S.A."

In a video on Saturday, Carney urged Canadians to buy domestic products, but did not directly mention Trump's tariff threat.

“With our economy under threat from abroad, Canadians have made a choice to focus on what we can control,” Carney said. “We can’t control what other nations do, we can be our own best customer.”

The Canadian prime minister this month traveled to China to reset the countries' strained relationship and reached a trade deal with Canada's second-biggest trading partner after the U.S.

Immediately after Carney's China trip, Trump sounded supportive. "It's a good thing for him to sign a trade deal," Trump told reporters at the White House on January 16. "If you can get a deal with China, you should do that."

“There is no pursuit of a free trade deal with China. What was achieved was resolution on several important tariff issues," Dominic LeBlanc, the minister responsible for Canada-U.S. Trade, said on Saturday in a post on X.

The Chinese embassy in Canada said in a statement to Reuters that China was ready to work with Canada to implement the important consensus reached by the leaders of the two countries.

U.S.-Canada tensions have grown in recent days following Carney's criticism of Trump's pursuit of Greenland.
