Buenos Aires hosts DEA drug enforcement summit

A closed-door Drug Enforcement Administration conference opens in Buenos Aires this week, bringing an estimated 400 to 600 senior officials to the Libertad Palace, according to El País. The three-day meeting—formally the 40th International Drug Enforcement Conference—is co-hosted by Argentina’s Ministry of Security and comes as President Javier Milei deepens his government’s security cooperation with Washington.

The gathering is being staged with unusual opacity for an event billed as “international cooperation”: the U.S. embassy says participants will coordinate intelligence-sharing and enforcement priorities against narcotics trafficking, international money laundering and “narco-terrorism,” but the names of senior DEA officials and other U.S. agency representatives have not been made public. El País reports that the selection of Buenos Aires reflects the close relationship between U.S. President Donald Trump and Milei, and it places Argentina inside a wider U.S. push to rebuild regional influence. In March, Trump launched the “Shield of the Americas” in Miami—an alliance of a dozen leaders aligned with his political agenda—explicitly bundling drug control with mass migration and competition with China.

For Latin American governments, the appeal of this framing is practical: it offers access to intelligence, training and diplomatic backing at a time when many states are struggling to control their territory. But it also tends to shift the center of gravity away from courts and investigators and toward agencies that measure success in seizures, arrests and border operations—metrics that travel well in press releases but do not necessarily reduce violence on the ground. El País notes that planning for the Buenos Aires conference began in 2025 under Patricia Bullrich, a security hardliner who previously sought to restore ties with the DEA after years of left-wing governments were reluctant to host U.S. involvement. Milei’s administration has intensified tougher border and security policies since taking office.

The guest list underlines the conference’s political balancing act. Mexico’s security secretary Omar García Harfuch is attending despite earlier tensions between the DEA and the government of President Claudia Sheinbaum, whose administration has publicly resisted aspects of U.S.-driven enforcement while facing cartel violence at home. Argentina’s delegation is led by Security Minister Alejandra Monteoliva, with officials portraying the summit as a stamp of legitimacy for their cooperation agenda. The conference also lands amid a broader regional rightward shift, which El País links to Washington’s renewed effort to set the terms of security policy across the hemisphere.

The event’s public face, however, is mostly the building and the security perimeter. The agenda is described in general terms, the sessions are closed to the press, and the most senior U.S. participants are unnamed.
