The China Securities Regulatory Commission (CSRC) is facing a reshuffle, as three senior regulators have either left or will leave soon.
The personnel changes have fuelled speculation that chairman Guo Shuqing will step up the CSRC's market reforms.
Zhu Congjiu, an assistant chairman of the CSRC, is set to be promoted to be a vice-governor of Zhejiang province, people close to the regulator said.
The promotion of Zhu follows the appointment of Gui Minjie, a former CSRC vice-chairman, as chairman of the Shanghai Stock Exchange last month.
Liu Xinhua, another vice-chairman, is expected to relinquish his responsibilities at the CSRC and move to the Shenzhen Stock Exchange as its chairman.
The CSRC spokesman was not available for comment yesterday.
