BEIJING - China has started to solicit public opinion on a provisional regulation on express delivery services, the Legislative Affairs Office of the State Council announced Monday.

The regulation said that courier companies should establish management systems for waybills and electronic data, regularly destroy waybills, and are prohibited from selling, leaking or illegally providing customers' personal information.

Those who violate these rules will face a fine of up to 100,000 yuan ($14,830) and have their license revoked, according to the regulation.

Companies who have leaked or are suspecting of leaking customers' information should report the situation to local postal administration departments, the regulation said.

The public may visit the official website (chinalaw.gov.cn) to submit their opinion before Aug 25.
