According to online reports, according to CCTV News, on July 12 local time, after the United States announced that it would impose a 30% tariff on Mexico starting from August 1, Mexican President Simbaum said she believed that she could reach an agreement with the United States before August 1. Speaking at an event, Sinbaum added that Mexico's sovereignty is not negotiable. Earlier in the day, U.S. President Trump posted a letter to the President of Mexico and the President of the European Commission on social platforms, announcing that starting from August 1, 2025, the United States will impose a 30% tariff on products exported to the United States from Mexico and the European Union. Trump claimed that Mexico had failed to prevent fentanyl and others from entering the United States and had not done enough to cooperate with the United States to prevent illegal immigrants from entering the United States. Mexico's Ministry of Foreign Affairs and Ministry of Economy said in a joint statement on the same day that the Mexican government believes this is "unfair treatment" and Mexico has begun negotiations with the United States to protect border businesses and jobs.
