Facing a sharp tumble in China's stock market in recent days, the government has announced a string of measures to bolster investors' confidence in order to stabilize the A-share market. Within three days, the authorities have announced 10 policies to boost the market.

The China Securities Regulatory Commission announced late on Wednesday that the two major stock exchanges and China Securities Depository and Clearing Company will lower transaction fees and transfer fees by about 30 percent.

Moreover, the draft of amended rules on margin trading, which was due to be released for public consultation on July 11, was also released on Wednesday evening, because of "special circumstances" the CSRC said on its official micro blog account.

The securities watchdog also announced on Wednesday that it would allow brokerages to issue bonds and explore securitization of margin trading business to widen their funding channels.

Brokerages are now allowed to issue or transfer short-term corporate bonds via stock exchanges and private equity trading systems between institutions, according to a statement of the CSRC.

Analysts expect the stamp duty is also likely to be lowered as a further measure to help the market.
