China and the United States are expanding cooperation on narcotics control, focusing on intelligence sharing, chemical regulation, and joint law enforcement investigations. Wei Xiaojun, executive deputy director of the Office of China National Narcotics Control Commission, confirmed that both nations are deepening efforts to disrupt drug supply chains, including the tracking of precursor chemicals and the repatriation of fugitives.
How is the US-China anti-drug cooperation evolving?
Law enforcement agencies in both countries have moved toward a model of practical collaboration rather than general dialogue. According to Wei Xiaojun, this includes regular communication between the Chinese Ministry of Public Security and US entities such as the Drug Enforcement Administration (DEA), the Federal Bureau of Investigation (FBI), and Immigration and Customs Enforcement (ICE).
A recent case highlights this operational shift. In February, Chinese police arrested a suspect named Gong following information provided by US authorities. Simultaneously, US law enforcement in Georgia arrested a US citizen tied to the same investigation. This synchronized action reflects a maturing intelligence-sharing framework aimed at dismantling transnational trafficking networks.
China has expanded its regulatory reach to include 412 non-medicinal narcotic and psychotropic substances. Starting July 1, 16 additional substances were added to the state-controlled catalogue to close loopholes used by illicit manufacturers.
What are the primary regulatory challenges for drug control?
While bilateral cooperation has improved, authorities face increasing complexity in monitoring chemical precursors. Wei Xiaojun noted that drug trafficking is becoming more organized, while the substances themselves are diversifying. The 2025 China Drug Situation Report indicates that while traditional drug cases decreased by 27.6 percent, the abuse of non-scheduled addictive substances is surging.

For example, seizures of nitrous oxide in China rose 84 percent year-on-year, and other non-scheduled substances saw a 17-fold increase. This shift toward “gray-area” chemicals complicates enforcement, as these substances often fall outside existing international scheduling protocols. To counter this, China’s customs and postal authorities have increased export supervision and risk analysis procedures.
Comparative Data: 2024 vs. 2025 Trends
Official data from the 2025 China Drug Situation Report shows a notable shift in enforcement outcomes compared to previous periods:
| Metric | Change |
|---|---|
| Drug-related cases solved | Down 27.6% |
| Suspects arrested | Down 33% |
| Total drug seizures | Up 25.4% |
What happens next in the fight against synthetic drugs?
Future efforts will likely focus on closing regulatory gaps in the chemical supply chain. China has committed to maintaining the current momentum, which officials describe as a “hard-won achievement.” The strategy involves a two-pronged approach: strengthening domestic industry self-regulation and refining the legal framework for precursor chemicals.
As trafficking methods evolve, international reliance on shared intelligence will remain critical. Wei Xiaojun emphasized that effective drug control is a global mandate requiring mutual trust. By aligning regulatory catalogues—such as the full inclusion of fentanyl-related substances and synthetic cannabinoids—both nations aim to reduce the availability of components used in illicit drug production in North America.
For researchers tracking global drug trends, the annual China Drug Situation Report provides the most granular data on precursor chemical seizures, which reached 550.6 metric tons in 2025.
Frequently Asked Questions
What substances are currently under control in China?
China regulates 412 types of non-medicinal narcotic and psychotropic drugs. This includes the entire category of fentanyl-related substances, synthetic cannabinoids, and nitazene-related compounds.

Is the US-China anti-drug cooperation effective?
According to the Office of China National Narcotics Control Commission, cooperation has resulted in successful joint investigations, the repatriation of fugitives, and the disruption of chemical supply chains that previously went unchecked.
Why are seizures of non-scheduled substances increasing?
Traffickers are increasingly exploiting “gray-area” substances that are not yet listed on international control schedules. This creates a cat-and-mouse dynamic where regulators must constantly update their lists to keep pace with new chemical variants.
