In its first ever official report on corruption, the Chinese government has acknowledged that the problem remains very serious.
The Chinese are promising tougher measures to win back public confidence and address the growing gap between rich and poor.
Authorities say more than 200,000 cases have been investigated since 2003. They say their efforts to date have "yielded notable results" but resolve to make them more effective, the BBC reports.
The document highlights new rules that require members of the Communist party to report incomes and investments to tackle these issues.
The party has also said it will curb excessive spending on official parties and seminars.
But critics say that corruption is ingrained in the system and new regulations will not solve the problem. They say fundamental reform is needed.
