The United States says China is the primary source of illicit fentanyl making its way onto American streets.
When President-elect Donald Trump announced a hike in his tariff plans for China, as well as U.S. trade partners Canada and Mexico, he drew attention to China’s involvement in the illicit fentanyl crisis in the United States.
The day one plan would add 10 percent duty on top of the tariffs Trump already has planned for Chinese products, and a 25 percent tariff on all products coming in through Canada and Mexico.
Trump said on Nov. 25 that the three countries have not done enough to help the United States stem illegal immigration and the entry of illicit drugs.
Over the past two administrations, including Trump’s first term, Beijing has made a number of promises to help curb the movement of illicit fentanyl but kept few of them.
Fentanyl is an FDA-approved synthetic opioid used to treat severe pain, such as in open-heart surgery, or epidurals for mothers in labor.
Illicit fentanyl, however, is often mixed with other drugs, and illicit drug makers are increasingly producing analogs, or drugs similar to fentanyl, with small molecular changes that can make the drug up to 100 times more deadly.
Fentanyl is already a potent drug—2 milligrams is enough to be a lethal dose depending on a person’s size.
Illicit fentanyl and its various analogs have been linked to nearly 400,000 deaths in the United States since 2016. The United States has identified China as the primary source of illicit fentanyl coming in across the border since at least 2017 and the source of other drugs years before that.
In 2023, the U.S. Drug Enforcement Administration (DEA) seized more than 80 million fentanyl-laced pills and nearly 12,000 pounds of fentanyl powder, representing 390 million lethal doses, more than the population of the United States.
Steve Yates, a China expert and former national security official in the George W. Bush administration, has made recommendations to Trump advisers on fentanyl policy. He and others say sanctions on Chinese banks for backing money launderers and chemical sellers will accomplish what diplomacy to date has not.
“When you don’t do those things, then you’re a doormat,” Yates told Reuters.
David Asher, a top former U.S. anti-money laundering official who helped target the finances of the Islamic State terrorist group, said this mechanism has been used against designated foreign adversaries like Iran but never Mexican or Canadian banks.
