More than 2 of 5 corruption cases involved tips

More than 40 percent of the cases investigated by the top Party discipline watchdog in 2012 involved tips from letters and calls.

Zhang Shaolong, a senior official with the Central Commission for Discipline Inspection of the Communist Party of China, reported the finding on May 7.

Combating corruption needs the public's support and participation, and reporting corruption through letters and calls provides an important way for the public to help in the battle, Zhang was quoted as saying on the People's Daily website.

He added that to let the public become more involved in anti-corruption efforts, authorities should take all means to open channels for the public to report on corruption.

Currently, the public can report through letters, visits and telephone, or log on to www.12388.gov.cn.

On April 19, some important official websites and mainstream commercial websites launched the online reporting channel. The daily access surged from 130,000 visits before the launch to 160,000 after.
