Thai police have arrested an alleged kingpin in Asia’s illegal trade in endangered species, dealing a blow to a family-run syndicate that smuggles elephant ivory, rhino horn and tiger parts to Chinese and Vietnamese dealers. Boonchai Bach, 40, a Vietnamese national with Thai citizenship, was arrested last Friday.  For more than a decade Bach and his family have reportedly run a widespread operation that has brought in millions of dollars from poached elephant ivory, pangolins, tigers, lions, and other rare and endangered animals. According to the Associated Press, Thailand had been considered to have the largest unregulated ivory market in the world and had been threatened with sanctions under the trade of protected wildlife species, but it introduced new laws and amendments in 2014 and 2015 to regulate domestic ivory markets and criminalize the sale of African elephant ivory.
