The Shenzhen Stock Exchange has formed a disciplinary committee, aiming to crack down on activities that breach regulations.

The 20 members of the committee had been approved by the exchange general manager's office, an exchange official said on Tuesday.

The committee would help safeguard the clean operation of the stock exchange, the official said.

A regulation of disciplines and penalties had been finalized and would go into effect on January 1 next year.

The Shenzhen Stock Exchange and the Shanghai Stock Exchange were both opened in 1990, marking the launch of China's securities market.
