System builds clean bidding for projects (2)

Liu Xichun, director of the bribery records center under the procuratorate, said: "Guilty companies will face restrictions on market access and on getting bank loans."

Incentives are also on offer to help companies turn a new leaf.

"For example, if the bribery conviction was more than 10 years ago, and the company has since then strictly followed the law, we may advise that they should be treated without prejudice," Song said.

Prosecutors will also work with other government departments to track companies that engage in corrupt undertakings, he said.

In addition, prosecuting authorities plan to establish a national database not just for bribery but for corruption, dereliction of duty, or abuse of power, Song said.

Bian Jianlin, a law professor with China University of Political Science and Law, said the system was working well but suggested that those who point fingers should also be checked to make sure that commercial rivals were not getting an unfair advantage.
