China has completed draft rules for the listing and trading of overseas companies on the international board at the Shanghai Stock Exchange, the bourse governor Geng Liang told reporters Monday.

Geng, who is also a member of the National Committee of the Chinese People's Political Consultative Conference, the country's top political advisory group, said public opinions about the rules would be sought after further revisions.

However, Geng said there was still no timetable for the launch of the board.

Earlier this year, Shang Fulin, chairman of the China Securities Regulatory Commission, has said that the commission would work with relative appropriate departments on a system allowing overseas companies to list on domestic bourses.
