China's securities regulator said on Friday it will not reopen the expected IPO floodgate, until details of the new share issuance system are released.

"More relevant regulatory measures about IPO issuance and underwriting will be published after we fix the reform policies, and any enterprise waiting to list new shares should get approval from the China Securities Regulatory Commission," said a spokesman for the commission.

The watchdog released a draft about IPO system reform on June 7, and Friday was the last day for collecting public opinions and proposals on the draft.
