President Trump implied in his social media post that the reason for the policy shift was rooted more on actions Mexico has recently taken to enforce better border security. After speaking with Claudia Sheinbaum of Mexico, I have agreed that Mexico will not have to pay tariffs on anything that falls under the USMCA agreement, President Trump said in his Truth Social post.

Following the tariff announcements, Trump held conversations with Canadian Prime Minister Justin Trudeau and Mexican President Claudia Sheinbaum, in which he expressed his concerns regarding border security. The Canadian and Mexican administrations made various commitments to take concrete steps on this issue. In response, Trump gave the Canadian and Mexican administrations 30 days to continue negotiations on border security, while postponing the tariffs.
