The trial of a British man and his American wife, who are accused of illegally obtaining and selling private information on Chinese nationals, could be key to a bribery investigation against pharmaceutical giant GlaxoSmithKline.
Peter Humphrey and Yu Yingzeng ran a risk consultancy called ChinaWhys, whose clients included GSK, and their testimony is being closely watched for any comments on the British firm.
The couple's arrest last year coincided with a government investigation into the company who are accused of funneling millions of pounds through travel agencies to bribe local doctors and health officials to raise prices and boost sales.
However, GSK was not mentioned on the charge sheet against Humphrey and Yu.
Prosecutors claim the couple have obtained over 200 items of private information including phone records and real estate documents and then re-sold the data.
