The Chinese Medical Doctor Association proposed to establish a blacklist system for unqualified medical workers and practise life bans on practicing medicine on anyone who has seriously violated medical ethics.

The proposals come after the industry and some of its members were tarnished by recent incidences of baby trafficking and receiving bribes from foreign pharmaceutical companies.

In the latest scandal exposed last week, 503 doctors at 79 hospitals in Beijing, Shanghai, Hangzhou and Guangzhou allegedly accepted a total of 1.69 million yuan ($276,000) in bribes from French pharmaceutical giant Sanofi-Aventis around November 2007.

The suggestions will be discussed by the association before being presented for approval to the National Health and Family Planning Commission.

No timeline has been set, the association added.
