The Jalisco New Generation Cartel, commonly known by the Spanish initials CJNG, is a Mexican criminal organization involved in international drug trafficking and associated financial and violent activity. It emerged around 2010 and developed a major position in Mexico’s drug economy. United States assessments identify it as a supplier of multiple drugs and a network with distribution connections beyond Mexico. Its history must now distinguish the period under Nemesio Oseguera Cervantes, known as El Mencho, from the leadership changes reported after his death in February 2026.

Origins and growth

DEA’s cartel profile traces CJNG’s formation around 2011 to remnants of the Milenio Cartel, which had been affiliated with the Sinaloa Cartel. It describes CJNG as becoming an independent organization alongside the closely connected Gonzalez-Valencia money-laundering organization, known as Los Cuinis. The profile identifies fentanyl, methamphetamine and cocaine trafficking among CJNG’s principal drug activities. These origins show continuity in personnel and financial relationships across organizational changes.

Drug markets and distribution

The DEA’s 2018 National Drug Threat Assessment described CJNG as based in the Guadalajara area and identified distribution connections in major United States markets, including Los Angeles, New York, Chicago, and Atlanta. Such an assessment identifies a trafficking presence and distribution relationships at a particular time. It does not mean the organization controlled all drug sales in those cities. The network model includes local intermediaries and transport arrangements whose roles can differ across locations and drug markets.

The UN Office on Drugs and Crime’s 2023 Global Report on Cocaine discussed Mexican organizations’ expansion and relationships with local actors in countries such as Ecuador. This places CJNG within a supply chain extending from production and export settings to transit and destination markets. International reach need not entail direct territorial administration at every point. Partnerships, purchasing arrangements, and local transport or security services can give an organization access to a route without making every participating group its subordinate.

Violence and the state response

Accounts of CJNG emphasize violence and the contest over territory, but episodes involving state forces require separate attribution. A 2019 PRISM discussion of Mexico referred to the 2015 Tanhuato operation and the national human rights commission’s findings concerning extrajudicial killings by police. Including such findings prevents the history of cartel conflict from treating all deaths in an operation as established combat deaths. The actions of a criminal organization and the legality of the response by security forces are distinct questions.

Terrorism designation

The United States designated CJNG as a Foreign Terrorist Organization on 20 February 2025, according to the DEA’s August 2026 account. That designation added a legal framework distinct from ordinary drug-trafficking charges. In particular, material-support prosecutions can address knowingly providing support to a designated organization under the applicable statute. The designation does not itself prove an alliance with a Middle Eastern organization or change the evidentiary status of every allegation made against individual cartel associates.

Leadership developments in 2026

A DEA announcement of 14 May 2026 reported that El Mencho had died after a military operation to capture him in February. It also reported the arrest by Mexican authorities of Audias Flores Silva, known as Jardinero, on 27 April. The announcement described Flores Silva as a potential successor before his capture, not as an established replacement leader. A superseding indictment returned on 13 May expanded earlier charges to include methamphetamine trafficking and a conspiracy to launder drug proceeds.

In August 2026, the DEA reported that court filings described Juan Carlos Valencia González as CJNG’s top leader following El Mencho’s death. The same announcement publicized charges against other senior figures and reward offers for information leading to arrests or convictions. Those reward amounts are enforcement incentives, not estimates of cartel revenue. The succession account is attributed to the government’s description of court filings, while the criminal charges against the named defendants remained allegations to be proved.

Finance beyond drug sales

The August announcement also described a separate case concerning alleged fraud against Americans who owned timeshare properties in Mexico. It reported wire-fraud and money-laundering charges and a 2025 superseding indictment that added material-support allegations against two defendants. This is significant because it identifies an alleged revenue stream beyond narcotics and shows the use of the organization’s terrorist designation in a financial case. It should not be represented as a conviction or as evidence that every timeshare business in Mexico was connected to CJNG.

International connections and limits

Research on Mexican criminal organizations’ foreign relationships examines how groups obtain supplies, markets, and services abroad. Such work distinguishes possible future partnerships from demonstrated operational arrangements. In CJNG’s case, international drug-market participation and designation as a terrorist organization do not establish a Hezbollah alliance. Claims about a particular partnership require evidence of the actors, transactions, and roles involved, rather than an inference from the two organizations’ appearance in discussions of transnational crime.

Place in the transnational crime record

CJNG’s trajectory combines organizational growth, multi-country drug distribution, conflict with rivals and security forces, and successive legal responses. The 2018 distribution assessment, the 2023 cocaine-market report, and the 2026 leadership and charging announcements describe different moments and types of evidence. Read together, they support an account of an evolving organization. They do not justify treating an older leadership profile as current, or converting an indictment’s account of command and responsibility into a final judicial finding.
