China's capital market has provided foreign investors with good returns and has a great potential of further attracting foreign capital, Yi said, citing that the proportion of foreign holdings in total A-share market capitalization has remained relatively low at less than 5 percent. 

Having learned from the best practice overseas, the country's registration-based reform has achieved breakthroughs with the stable operation of the registration-based initial public offering system on Shanghai's STAR Market and Shenzhen's ChiNext, Yi added.

"We will proactively create conditions for carrying out the registration-based reform across the whole marketplace," Yi said, adding that the commission will take multiple measures and improve related rules to ensure a smooth transition to the registration-based system.

For instance, the commission will urge intermediary institutions to improve their capability and further fit in the new system, Yi said, citing that some IPO sponsors are yet to be fully adaptive to the registration-based system, which has led to withdrawal of some IPO filings recently.

Yi added that the registration-based system does not mean relaxing review requirements. Shanghai and Shenzhen stock exchanges have stringently performed their duty of IPO review, while the CSRC has examined review quality of the exchanges and other major aspects such as issuers' information disclosure under the registration-based system.

The above measures have been effective and necessary, he said, citing that regulators in major markets overseas like the US also implement strict arrangements over issuance review and registration.
