Following up on strong words about enforcement, the head of the China Securities Regulatory Commission, Xiao Gang, said his agency would double its investigative team with 600 new staff.

The plan, disclosed by Xiao on the agency's website on Tuesday, is widely seen as a signal that the CSRC is taking serious steps to address deficiencies in the capital markets.

Earlier at an internal work conference, Xiao urged his staff to step up their efforts in investigation and enforcement.
