Recent enforcement actions highlight intensified bilateral cooperation between U.S. agencies such as the DEA and Mexican authorities, including the Navy and federal security forces, through joint task forces and intelligence sharing. In October and early November 2026, Mexico arrested several regional commanders linked to the Jalisco New Generation Cartel, including Ivan Cazarin Molina in Jalisco and Samuel De la Cruz Anaya in Veracruz, alongside figures from smaller groups and Sinaloa-linked networks. These operations followed earlier 2026 designations of cartels as foreign terrorist organizations and targeted high-value individuals involved in drug trafficking, extortion, and fuel theft. Ongoing investigations into financial networks and corruption cases, such as the recent arrest of a Mexican judge in Colombia on related bribery charges, continue to shape prospects for additional arrests before year-end.
