MEXICO CITY (AP) — Mexico President Claudia Sheinbaum denied her administration had an agreement with the U.S. Drug Enforcement Administration Tuesday, hours after the U.S. agency announced “a major new initiative” to collaborate in the fight against drug cartels.

The U.S. Drug Enforcement Administration announced the “bold bilateral initiative” against narco-trafficers Monday. On Tuesday, Mexico’s president said her country doesn’t have an agreement with the DEA.
