Kathmandu. U.S. President Donald Trump has threatened to impose tariffs on all goods coming through Canada’s border if Canada signs a trade deal with China.

Relations between the United States and its northern neighbour have been strained since Trump returned to the White House a year ago.

Canadian Prime Minister Mark Carney condemned the trade dispute and the “fragmentation” in the US-led world order.

During a visit to Beijing last week, Carney praised the new strategic partnership with China. This led to an “initial but historic trade agreement” to reduce tariffs.

“If Carney wants Canada to be a drop-off port for China to send goods to the United States, he’s wrong,” Trump wrote on Truth Social. It will completely disrupt and affect their business, social media and general lifestyle.

“If Canada makes a deal with China, Washington will immediately strike with 100 per cent tariffs for all Canadian goods and products coming into the United States,” Trump said. ”

The two leaders have turned their rhetoric against each other in recent days. It began with Carney’s speech at the World Economic Forum in Davos on Tuesday. At the conference, he was greeted with loud applause as he made a clear assessment of the “fragmentation” of the American-led world order.

His comments were seen as a sign of Trump’s disruptive influence in international affairs, though he did not mention the US leader directly.

Trump responded to Carney in his own speech in Davos a day later, after which he withdrew an invitation to the Canadian prime minister to join his self-proclaimed peace committee to resolve global conflicts.

Initially designed to oversee the situation in post-war Gaza, it now appears to be trying to broaden its scope. There have been concerns that President Trump wants to turn the committee into a rival body to the United Nations.

“Canada doesn’t survive because of the United States, but because Canada can thrive in a remarkable partnership between two nations.” We’re Canadians,” Carney said in a national address Thursday.

Canada relies heavily on trade with the United States, with the U.S. accounting for more than three-quarters of Canada’s exports.

Key Canadian sectors such as cars, aluminum and steel have been hit hard by Trump’s policies of increasing global regional tariffs, but the impact of the tariffs has been mitigated by the president’s broad adherence to existing North American free trade agreements.
