Trump wants to renegotiate US-Canada border agreement – NYT

US President Donald Trump stated that he does not recognize the treaty defining the border between the United States and Canada and has expressed his intention to renegotiate it, according to The New York Times.
During a conversation with Canadian Prime Minister Justin Trudeau, Trump said that he did not consider the treaty defining the border between the United States and Canada to be valid.
Moreover, he indicated a desire to renegotiate the agreement but did not provide further explanations.
The treaty in question, signed in 1908, established the international border between Canada, then a British dominion, and the United States.
Trump also expressed interest in revisiting agreements on the shared use of lakes and rivers between the two countries, which are regulated by multiple treaties. He has previously shown interest in this issue.
Canadian officials have taken Trump's remarks seriously, particularly given his past statements about wanting to bring Canada to its knees.
Recently, Trump suggested he could use economic power to make Canada the 51st US state. However, when pressed by reporters, he clarified that he does not consider military force as an option for Canada’s hypothetical annexation.
Earlier this month, Trudeau stated that the US had started a trade war against Canada.
Notably, on March 4, Trump’s new 25% tariffs on goods from Mexico and Canada, along with a tariff increase on Chinese imports from 10% to 20%, took effect.
Mexican President Claudia Sheinbaum has announced that Mexico will retaliate against US tariffs by imposing reciprocal duties on American products.
