China's top stock securities watchdog is having a few problems regulating itself. The China Securities Regulatory Commission (CSRC) has posted a notice on its website warning that a scam artist posing as a CSRC official has attempted to solicit money from unsuspecting companies. The unknown individual contacted listed companies and requested payment for official CSRC books and seminars. The imposter apparently obtained a counterfeit seal from the CSRC's legal department and then asked listed companies and securities companies to buy the products. In the notice dated November 6 but posted on November 10, the website said the person 'cheated' various companies but did not say how much he or she stole. CSRC's legal department said information concerning the scam had been given to prosecutors. It also provided a number for people to call if they received any suspect solicitations. 'This may or may not suggest the problem was severe but the CSRC deserves a thumbs-up for disclosing something that might be perceived as embarrassing,' said Walter Hutchens, an assistant professor of business at the University of Maryland.
