MEXICO CITY (AP) — President Claudia Sheinbaum suggested Tuesday that Mexico could retaliate with tariffs of its own, after U.S. President-elect Donald Trump threatened to impose 25% tariffs on Mexican goods if the country doesn’t stop the flow of drugs and migrants across the border.

The 25% proposal marked an escalation from his campaign claims, as the ex-president previously proposed raising tariffs by 10%, or by 60% on goods imported from China—which is up from approximately 1% and 11% now, respectively, according to data from research firm Wolfe Research cited by the Wall Street Journal.
