Update | Dongguan sex trade boom fuelled by exports slump
Police crackdown surprised no one as the former industrial hub's steamy sex trade took off just as its exports went off the boil in 2009

It took two CCTV exposés to prompt Guangdong officials to crack down on the sex trade in Dongguan, but the city has been a hotbed of vice for years.
Once an industrial hub of the Pearl River Delta, the sex trade took off as its exports began to lose steam in 2009.

Despite occasional crackdowns, business thrived, and the term "Dongguan-style" even made its ways into the lexicon of the prostitution business.
Before the financial crisis, businessmen from the mainland and overseas thronged the more than 100 swank hotels spread across the city, cutting deals with the delta's many manufacturers. But when contracts dried up, no one had a reason to visit.
