MEXICO CITY (Reuters) -Fentanyl trafficking from Mexico to the United States has fallen around 40% since U.S. President Donald Trump took office in January, Mexican President Claudia Sheinbaum said on Friday.

Trump has cited fentanyl trafficking as a factor in his decision to put tariffs on Mexico, though many shipments are not affected, as they enter the country under a trilateral trade agreement.
