The social subsistence fee, a compulsory levy paid by families who have more children than the family planning policy allows, will be strictly monitored to prevent corruption, according to the country's top auditor.

The authorities have not carried out a thorough audit of the social subsistence fee in recent years, the National Audit Official said in an announcement on its website on Monday.

Auditing agencies will also monitor many other projects closely tied to the people's interests, such as government funds for agricultural water projects and poverty-reduction programs.
