Second Meeting of the U.S.-Mexico Security Implementation Group

On December 11, representatives from six United States government agencies and their Mexican counterparts convened the second Security Implementation Group (SIG) meeting in Mexico City, advancing security cooperation as sovereign partners to improve the safety and welfare of citizens on both sides of the border. Ending the illicit trade in fentanyl that kills thousands of Americans annually is a primary focus of this effort.  The SIG is pursuing decisive action against financial institutions and individuals complicit in the manufacture, distribution, and sale of fentanyl and precursor chemicals.  The delegations committed to accelerating joint efforts to dismantle Foreign Terrorist Organizations (FTOs), and other criminal groups, disrupt illicit revenue streams, and counter emerging threats.

Both nations committed to enhancing intelligence sharing and linking analytical platforms to pre-empt and respond to drone attacks at the border.  The United States and Mexico agreed to deepen and streamline collaboration on extraditions, asset forfeiture, and fuel-theft investigations and committed to reconvening in January 2026.
