Claudia Sheinbaum issued a sharp warning in both a letter and an official statement in Spanish, vowing that Mexico would respond in kind if Donald Trump imposes steep trade tariffs when he becomes U.S. president in January. She cautioned that such tit-for-tat moves would increase until they “put our shared enterprises at risk.” Sheinbaum emphasized that migration through Mexico to the United States is declining, that the country has made large drug seizures, and that Mexico bears the brunt of cartel violence fuelled by American guns and the U.S. demand for drugs.

Talking point: Sheinbaum’s harsh response contrasts with Canada’s reaction on Tuesday, in which ministers mostly talked about making the case for the economic benefits of free trade. Mexico’s president also took a swipe at Canadian leaders, reminding them that Canada is only in the continental USMCA treaty because her predecessor stopped the Trump administration of 2018 from cutting Canada out.  Everybody is benefitting, she said: “We complement each other.”
