Donald Trump threatened to apply tariffs on Mexican auto imports to the US if Mexico does not “do enough” to prevent illegal immigration into the US and “crack down on drugs crossing the border.” Trump said he would give Mexico a year to prevent immigrants from entering the US before implementing the tariff.
Trump also threatened to close the US southern border if immigrants continue to enter the US through Mexico, backing off from a previous threat to close the border in the near-term.
"If Mexico doesn't help, that's okay. We'll tariff their cars," he said in a press conference. "I will do it; I don't play games."
However, Congress is currently working to ratify the NAFTA replacement trade deal, and enacting new tariffs on cars would violate the agreement, which has been signed by the leaders of the US, Canada, and Mexico.
