Doing credible due diligence on potential Chinese partner companies is a nightmare. But British risk assessment analyst Peter Humphrey has found that trying to get at the truth is costing him two and a half years in prison and a fine of nearly $36,000. Humphrey, who has run his ChinaWhys risk consultancy in Shanghai and Hong Kong for more than a decade, was convicted of storing “illegally obtained private information” on his computer. This included data gathered during an investigation for GlaxoSmithKline into the origins of a videotape of the head of the company’s China division having sex with his girlfriend.
