BEIJING - Provincial level officials and ministers will be held more fiscally responsible under an expanded auditing system, the country's top auditor said on Thursday.

"The regulation will be significant in supervising officials' power use and corruption prevention," Liu Jiayi, head of the National Audit Office, was quoted as saying in an interview posted on the office's website.

Under the regulation, released by the general offices of the Communist Party of China (CPC) Central Committee and the State Council, leaders of public institutions and State-owned enterprises will also be audited.
