Police move to tackle rise of 'white-collar' drug producers

In a development that echoes TV's Breaking Bad, some Chinese chemistry professionals have begun producing and selling illegal substances. Zhang Yi reports.

The manufacture and distribution of illegal narcotics is undergoing a transformation in China.

While a large part of the problem remains the involvement of criminal gangs and street thugs who control the localized trade, the emergence of sophisticated labs and international distribution networks set up by white-collar entrepreneurs is presenting a new challenge for the authorities.
