The top anti-graft watchdog is taking a series of measures, including punishing its own officials who are easily bribed, strengthening discipline and consolidating its role, amid the ongoing clean-governance campaign.

The Central Commission for Discipline Inspection of the Communist Party of China said anti-graft authorities nationwide should "keep their hands clean" before investigating others.

The commission made the remarks on Thursday while announcing the launch of a campaign to fight corrupt activities at disciplinary authorities' training centers.
