China's Communist Party sacks assistant chairman of stock regulator - Xinhua
Zhang Yujun was under investigation for suspected "serious violation of discipline", the country's graft watchdog reported on Sept 16, using the euphemism it employs for corruption.
Zhang is the first China Securities Regulatory Commission (CSRC) official to come under investigation amid stock market turmoil, which started in June.
