Argentina Designates CJNG as Terrorist Organization — Strategic Win for Sinaloa Cartel

Argentine President Javier Milei's government designated the Jalisco New Generation Cartel (CJNG) as a terrorist organization on March 26, 2026, adding it to Argentina's national terrorism registry (RePET). The designation follows the February 2026 killing of CJNG founder Nemesio 'El Mencho' Oseguera Cervantes and marks a significant policy escalation in Latin America's approach to Mexican organized crime. Analysts note the move will pressure Argentine criminal networks tied to CJNG for cocaine transshipment routes to Europe, potentially benefiting rival Sinaloa Cartel operations in the Southern Cone. CJNG fighters had previously been deployed into Sinaloa to support Los Chapitos in the intra-Sinaloa Cartel war.
