The party’s Central Commission for Discipline Inspection is probing officials at the China Securities Regulatory Commission on suspicion of using inside knowledge of this summer’s stock-market rescue for personal gain, The Wall Street Journal reported, citing unnamed agency officials. The officials said the CCDI had been taking officials to a hotel near the CSRC’s headquarters to press them for a confession or to report on others at the equities regulator. The sources said two top CSRC officials had already been removed from their posts and placed under investigation on suspicion of leaking the government’s policy moves to private investors who used it to reap profits.
