Canada has “no intention” of pursuing a free trade deal with China, Prime Minister Mark Carney said, after U.S. President Donald Trump threatened to slap punitive tariffs on Ottawa.

Speaking to reporters on Sunday, Carney said that the country respects its obligations under the Canada-U.S.-Mexico trade agreement, known as CUSMA in Canada and the USMCA in the U.S., and will not pursue a free trade agreement without notifying the other two parties.

Carney’s remarks come after Trump threatened to put a 100% tariff on Canadian exports if Ottawa “makes a deal” with Beijing.

“If Governor Carney thinks he is going to make Canada a ‘Drop Off Port’ for China to send goods and products into the United States, he is sorely mistaken,” Trump posted on Truth Social Saturday.

The remarks come against the backdrop of rising tensions between the U.S. and Canada, with Trump last week withdrawing the invitation to Ottawa to join his “Board of Peace,” after Carney in his address at the World Economic Forum in Davos warned against economic coercion by the world’s superpowers.
