Fixed income chief Dai Xu at China Galaxy Securities (6881.HKG), along with two other employees, are cooperating with China’s judicial authorities, Bloomberg reported, citing a statement from the company. The staff are involved “due to personal reasons,” the company, a Hong Kong-listed broker partly owned by China’s sovereign wealth fund, said yesterday in a statement to Hong Kong’s stock exchange. The announcement came after Chinese media reports of government probes in the securities industry focused on corporate-bond underwriting and issuance. The Beijing-based company didn’t draw any link with such investigations in its statement.
