US-Mexico Wrap Third Round of USMCA Talks as New Tariffs Bite

USTR Greer and Mexican Secretary of Economy Marcelo Ebrard concluded a third bilateral round in Washington, reporting 'constructive' progress on steel, aluminum and Asian-import substitution even as new Section 338 tariffs on Canada took effect in parallel. Mexico's own tariff exposure stayed largely capped near the pre-existing 10% baseline outside USMCA.
