The Communist Party of China's (CPC) top anti-corruption body has completed its largest training session of municipal district Party discipline inspection chiefs since the training session was inaugurated in 1978, according to the People's Daily.

The one-month training session was concluded on Monday.

The training for all 850 municipal district anti-corruption chiefs was held by the CPC Central Commission for Discipline Inspection.

The CPC Central Commission for Discipline Inspection held similar anti-corruption training sessions for Party discipline inspection chiefs from 2,000 counties and 400 cities in May 2009 and June 2010.

The three sessions were similar, Fan Yaogeng, an official with the commission, said.

Besides training anti-corruption officers, the CPC has taken other measures to combat corruption, the most significant of which is a rule requiring officials to declare their assets.

A regulation that took effect Sunday expands the list of assets officials must declare. The regulation adds six more items to the list of declarable assets issued in 2006, bringing the total to 14.

The new items include income from sources like lecturing, painting and calligraphy; homes owned by spouses and children; and equities and investments owned by officials, their spouses and children.

Officials can be dismissed for failing to report assets honestly and promptly, according to the rule.
