Mexican President Claudia Sheinbaum said progress was being made toward a potential trade agreement with the United States after a "very good" call with President Donald Trump on Wednesday. Foreign Minister Roberto Velasco and Economy Secretary Marcelo Ebrard also joined the discussion. Sheinbaum did not disclose details, saying they would remain private until an agreement is reached. Mexico is seeking lower U.S. tariffs on steel, aluminum and automobiles, while negotiating rules of origin and measures to strengthen North American supply chains. The talks form part of the review of the United States-Mexico-Canada Agreement, or USMCA, amid uncertainty after Trump said Thursday he was considering changes to trade relations with Mexico.
