MEXICO CITY, July 18 (Reuters) - Precursor chemicals used by Mexican cartels to make the deadly opioid fentanyl do not come from China, its embassy in Mexico said on Tuesday, rejecting U.S. officials' accusations.
China had denied the illegal trafficking of fentanyl to Mexico in an April statement, though it did not address precursor chemicals.
The embassy on Tuesday said China was "actively coordinating and strengthening" supervision of drug-making substances with Mexico.
The U.S. embassy in Mexico and Mexico's foreign ministry did not immediately respond to requests for comment.
Last week, the U.S. Treasury sanctioned 10 people with suspected ties to the Sinaloa Cartel's fentanyl network, as well as a company accused of importing chemicals from China.
