Hong Kong customs interdicted a record HK$125 million (B533m) marijuana shipment from Thailand, discovering 535kg of cannabis concealed in insulated boxes aboard a container ship. Three arrests were made. The seizure underscores growing cross-border drug trafficking flows through Southeast Asian ports and stricter enforcement in Hong Kong, with customs data showing a 27% surge in marijuana seizures year-to-date—relevant context for Thai exporters, logistics operators, and supply-chain compliance teams managing trade with Hong Kong and mainland China.
