XINGTAI, China--A Chinese court on Thursday imprisoned nine people, one of whom received a suspended death sentence, on charges of smuggling fentanyl into the United States, in the first such case the two countries have worked on together.

  China has faced U.S. criticism for not doing enough to prevent the flow of fentanyl into the United States, and the issue has become another irritant in bilateral ties, already strained by a bruising trade war the two are now working to end. The joint announcement of the successful action against smugglers, in front of a group of Chinese and foreign reporters invited by the Chinese government, comes as the two countries are expected to be close to signing an interim trade deal.
  Fentanyl is a highly addictive synthetic opioid, 50 times more potent than heroin. It is often used to make counterfeit narcotics because of its relatively cheap price, and it has played an increasingly central role in an opioid crisis in the United States.
  Yu Haibin, a senior official with China's National Narcotics Control Commission, told reporters in the northern city of Xingtai, where the court case was heard, that Chinese and U.S. law enforcement had worked together to break up the ring. Members were accused of smuggling fentanyl and other opioids to the United States via courier.
  The case originated in 2017 from the Department of Homeland Security's New Orleans office, which acted on a tip from an informant who provided contact information for a Chinese seller using the pseudonym "Diana," Austin Moore, a regional attache with the department, told reporters.
  One of the people sentenced by the court was given a suspended death sentence - which in practice is normally commuted to life in jail - and two got life sentences, Yu said. He said the case should not be connected to politics or the trade war, and the timing of the sentencing was the result of the legal process. There are two other joint fentanyl cases ongoing, he said.
  "This should not be linked to trade, or other policy-related matters, because there's nothing more important than a human life," he said.
  Jim Carroll, head of the White House Office of National Drug Control Policy, said the arrests were a positive step. "We look forward to further cooperation to stop the flow of these deadly substances into the United States," Carroll said in a statement.
