• DEA announces “Project Portero” to disrupt cross-border smuggling routes.
  • Mexico’s President Claudia Sheinbaum denies any agreement with U.S. officials exists.
  • Conflicting statements raise questions about U.S.-Mexico cooperation on cartel enforcement.

MEXICO CITY (TDR) — Hours after the U.S. Drug Enforcement Administration unveiled what it called “a major new initiative” with Mexico to target criminal gatekeepers controlling cross-border smuggling routes, Mexican President Claudia Sheinbaum flatly denied that any such agreement exists.

Speaking at her morning news conference Tuesday, Sheinbaum dismissed the DEA’s claims about Project Portero, which the agency had promoted as a “flagship operation” to disrupt the flow of drugs, firearms, and illicit money into the United States.

“The DEA put out a statement yesterday saying that there is an agreement with the Mexican government for an operation called Portero,” Sheinbaum said. “There is no agreement with the DEA.”

Conflicting Accounts

The rebuke comes just days after U.S. and Mexico officials had reportedly negotiated trade and security deals, including the transfer of high-ranking cartel figures. Sheinbaum insisted that her administration is only pursuing a broader security agreement grounded in sovereignty, mutual trust, territorial respect, and coordination without subordination.

She clarified the only current activity was a workshop in Texas attended by four members of Mexico’s police.

The DEA’s statement, however, had pointed to that very workshop, describing it as a collaborative exercise where Mexican investigators trained at one of its intelligence centers alongside U.S. prosecutors, defense officials, law enforcement, and members of the intelligence community.

DEA Pushes Back

“DEA is taking decisive action to confront the cartels that are killing Americans with fentanyl and other poisons,” Administrator Terrance Cole said.

In a separate statement, Cole asserted:

“Project Portero and this new training program show how we will fight—by planning and operating side by side with our Mexican partners, and by bringing the full strength of the U.S. government to bear. This is a bold first step in a new era of cross-border enforcement, and we will pursue it relentlessly until these violent organizations are dismantled.”

A Growing Rift

For Mexico, however, the denial underscores its insistence on territorial sovereignty — a theme Sheinbaum has emphasized since taking office. The contradiction between U.S. announcements and Mexican rebukes could complicate not only cartel strategy but also the diplomatic relationship at large.

Sheinbaum reiterated: “The DEA puts out this statement, based on what we don’t know. We have not reached any agreement, none of the security institutions [have] with the DEA.”

The sharp divergence between Washington and Mexico City raises doubts about whether “Project Portero” represents a true operational partnership — or a public relations effort by the United States to showcase toughness on cartels while Mexico resists formal subordination.

Will U.S.-Mexico cooperation collapse before it even begins, or is this clash simply the start of harder bargaining?
