China's anti-narcotics authorities opened an investigation in October 2025 into a large transnational network smuggling liquid methamphetamine into Indonesia; a year-long probe found repeated shipments. In September 2026 China's National Narcotics Office notified Indonesia's National Narcotics Agency and the parties agreed to cooperate; the Royal Malaysia Police's Narcotics Division assisted. On Oct. 21 Indonesia's National Narcotics Agency dismantled a major purification/production site in Banda Aceh, seized about 1.2 tonnes of liquid methamphetamine and arrested 11 suspects. Chinese authorities said the case is the largest recent cross-border narcotics bust China has carried out with other countries by number of arrests and completeness of the interdiction chain.
