Cracking Down on Bond Market's Knotty Traders

(Beijing) -- It was a typical workday morning at Wanjia Asset Management Co. in Shanghai's downtown financial district, but the firm's star bond trader Zou Yu was not at his desk.

Zou, 31, had mysteriously failed to report for his job as head of Wanjia's fixed-income department. And his whereabouts remained unknown until five days later when the firm, on April 16, announced that the police had taken Zou into custody for alleged, unspecified financial crimes.
