A new agreement in place could be a major step towards curbing the opioid crisis in New York state, according to Sen. Chuck Schumer.

The Senate majority leader met with China’s President Xi Jingping last month to demand an immediate stop to the fentanyl flow into America.

The senator detailed a new deal on Thursday, in which China agreed to enforce its own regulations against synthetic drug suppliers.

However, the senator says he will be watching China very closely.

“China has agreed to stop the scourge of fentanyl, but I am here to say we now have to hold China accountable to make sure that these commitments are kept,” said Schumer.

China and the United States will also be launching a counter narcotics working group to bolster law enforcement and information sharing to cut off the flow or precursor drugs and illicit fentanyl.
