MEXICO CITY — Mexico’s president responded angrily Tuesday to President-elect Donald Trump’s pledge to impose a 25 percent tariff on its products if the country didn’t curb the flow of irregular migrants and fentanyl, warning that the penalties would only wind up causing inflation and unemployment in the United States.

Claudia Sheinbaum said Mexico suffered from an influx of weapons smuggled in from the United States, and that drugs were a U.S. problem.
