Thai authorities intercepted nearly 900 kg of crystal methamphetamine hidden in a cargo shipment at Bangkok's Port Custom Office and bound for Taiwan where it has a marketplace value of up to $A127 million, a customs official said.
The drug was seized by customs officials late on Friday, hidden in powder form inside 161 white silicon slabs in packages destined for Taiwan.
"The 897 kg of crystal meth is worth about 500 to 600 million baht ($A21 million to $A26 million), but once they reach their destination they will be worth 3 billion baht ($A127 million) in market price," Thai Customs Director-General Patchara Anuntasil told a press conference on Saturday.
Patchara said that Thai and Taiwanese authorities were both investigating.
The methamphetamine market has continued to expand and diversify in East and Southeast Asia, unaffected by the coronavirus pandemic.
In October, police in neighbouring Laos seized a record haul of 55 million methamphetamine tablets and over 1.5 tonnes of crystal methamphetamine tablets in the Golden Triangle region where the borders of Myanmar, Thailand and Laos meet.
The Golden Triangle has a long history of illicit drug production and has recently served as a massive production centre for amphetamine-type stimulants, especially methamphetamine, used by Asian crime syndicates with distribution networks reaching as far as Japan and New Zealand.
