China unveils fentanyl curbs ahead of Xi's US state visit, envoy calls it 'historic milestone'

China's ambassador to the US, Xie Feng, framed Xi Jinping's upcoming state visit as a 'historic milestone' while Beijing announced new stringent fentanyl regulations, signaling a goodwill gesture to build diplomatic momentum. The move suggests a deliberate effort to de-escalate bilateral tensions on a key US domestic concern, though the scope and enforcement of the new rules remain unclear. This development matters as it could set a cooperative tone for the summit and potentially ease trade and security frictions.
