Sustain vigor

Admittedly, China's markets regulator has stepped up efforts to check insider trading to protect ordinary investors, but that is insufficient to effectively crack down on illegal trades based on non-disclosed market information.

The China Securities Regulatory Commission (CSRC) must show more spine than simply shooting sitting ducks if the campaign has to show any teeth and resulted in higher conviction rates for offenders.

The CSRC has launched 51 probes into insider trading so far this year compared with 33 such cases last year.
