BEIJING, July 2 -- China has kicked off a new round of anti-corruption inspections as Communist Party of China (CPC) graft-busters marched into 11 key state organs and companies.

The 11 included the State Council's Leading Group Office of Poverty Alleviation and Development, the People's Daily and the China North Industries Group Corporation, a main weapons and equipment research and development body.

The National Railway Administration, China Post and the administration for offices directly managed by the CPC Central Committee are also among those targeted, according to a government statement released Thursday.

A total of 26 Party and government offices or firms will be targeted in the new inspection tour, the second of this year.

Inspectors will stay at these organs for two months and invite complaints and tip-offs, said the statement.

The inspection system is regarded as an effective method for CPC to uncover internal corruption and improve work style. The central inspection teams are jointly sent by the CPC Central Commission for Discipline Inspection and the Organization Department of the CPC Central Committee. They have completed six rounds of inspections since late 2012.

Wrongdoings were publicized and some officials were fired following the inspections. In the latest inspection results publicized last month, authorities slammed all the targeted 26 state firms, including PetroChina and China Mobile, for "a string of problems" such as traveling on public funds, stealing state assets and nepotism.
