China's Supreme People's Procuratorate (SPP) will set up a national online database of convicted bribers by the end of this year, in a bid to prevent possible corruptions.

The database will serve as an admittance control mechanism in the bidding and government procurement procedures, said a statement from the SPP on Sunday.

China has put online lists of convicted bribers, making such information available for public inquiry from 2006 and the blacklists have effectively deterred some cases of corruption as well as commercial bribery, the SPP's statement said.

The SPP also called on procuratorial organs in the country to improve their crime reporting systems for the reference of policy makers.
