Seizures of high-purity crystal methamphetamine have surged more than tenfold in Thailand over the past two years, statistics show, a stark indicator of the growth in industrial-scale production of the stimulant in neighboring Myanmar.

Thailand is a major trafficking route for crystal meth manufactured in Myanmar's Shan and Kachin states, where police say Asian organized crime groups have allied with local pro-government militias and armed rebels to set-up "superlabs."

The drug syndicates have distributed the meth across the Asia-Pacific region, from South Korea to New Zealand and most countries in between, authorities say.
