NASDAQ is a stock exchange. Financial institutions as a class of companies have pretty strict regulations/compliance issues about who can work in them. For example, they fingerprint every exchange employee and typically bar convicted felons from even applying. Being a agent of another state--and certainly if not disclosued-- is such a red flag for fraudulent behaviour as to not need further explanation. A foreign agent has the means and motive to harm both the exchange members and the host nation, and providing them with corporate security clearance equates to a the opportunity for criminal behaviour (either as a principal or an accomplice).
