The authorities in Thailand are extending their investigation into the diversion of cold tablets for the production of the illegal stimulant methamphetamine to other countries.
The move comes after the authorities found that huge quantities of the tablets may have been illegally imported from China and South Korea.
Department of Special Investigation director-general Tharit Phengdit said yesterday that his agency found documents about a Thai company’s deal to purchase 10 billion pseudoephedrine-based cold pills from a Chinese firm.
He said it also found evidence of illegal purchases and shipments of such drugs from South Korea.
Thailand is a major market and transit point for methamphetamine.
