Mexico is ending its unprecedented open relationship with U.S. security agencies that developed in recent years to fight drug trafficking and organized crime.

All contact for U.S. law enforcement will now go through “a single window,” the federal Interior Ministry, the agency that controls security and domestic policy, said Sergio Alcocer, deputy foreign secretary for North American affairs.

Alcocer confirmed the change to The Associated Press on Monday, three days before U.S. President Barack Obama visits for his first bilateral meeting with his Mexican counterpart, Enrique Pena Nieto, who took office Dec. 1.
