A major shift in U.S. policy has raised tensions with Mexico after Donald Trump moved to classify certain Mexican cartels as foreign terrorist organizations. The designation changes the legal framework significantly, allowing broader financial sanctions, expanded surveillance authority, and stricter penalties for anyone accused of supporting those groups. What had long been treated as a cross-border crime issue now edges closer to a national security matter.
From Mexico’s side, President Claudia Sheinbaum has pushed back firmly, emphasizing national sovereignty. Her administration has made clear that cooperation with the United States cannot come at the expense of control over Mexican territory. At the same time, Mexico has highlighted concerns about the flow of illegal firearms from the U.S., arguing that responsibility for cartel violence extends beyond its borders.
