(CNN) — Mexico has handed an alleged Chinese fentanyl kingpin over to authorities in the United States, where he is wanted for money laundering and drug trafficking.

Zhi Dong Zhang is accused in court documents of exporting, transporting and distributing more than 1,000 kg of cocaine and 1,800 kg of fentanyl as well as laundering more than $150 million in illegal annual profits, according to CNNE.
