China has released new judicial guidelines for handling criminal cases involving fentanyl-related substances, clarifying sentencing criteria and dividing controlled substances into medicinal and non-pharmaceutical categories. The measures, announced jointly by China's Supreme People's Court, Supreme People's Procuratorate, and Ministry of Public Security, come one day before President Xi Jinping is set to meet U.S. President Donald Trump in Washington for their second summit of the year. Beijing also added two chemicals to its export control list for drug precursors, requiring permits for shipments to the U.S., Mexico, and Canada — a move likely aimed at addressing longstanding American pressure on China to curb the flow of fentanyl ingredients into the United States.
