Canadian Prime Minister Mark Carney says his country stands ready to build on trade talks "when the Americans are ready to have those discussions."

“We can’t control the trade policy of the United States. We recognize that that policy has fundamentally changed from the 1980s,” Carney said Friday morning before boarding a flight to Asia. “We have to focus on what we can control and realize what we can’t control.”

U.S. President Donald Trump complained about Canada because of recent television ads protesting U.S. tariffs, which he calls “egregious behavior” aimed at influencing U.S. court decisions.

The Republican president posted Friday morning on his social media site that “CANADA CHEATED AND GOT CAUGHT!!!” on the tariff ads. Trump late Thursday said he's ending “all trade negotiations” with Canada.

Trump's social media post late Thursday came after Canadian Prime Minister Mark Carney said he aims to double his country’s exports to countries outside the U.S. because of the threat posed by Trump’s tariffs.

Trump’s call for an abrupt end to negotiations could further inflame trade tensions between the neighboring countries.
