China's top disciplinary body has pledged to persist with its iron-handed crackdown against corruption and other misconduct.

In an article published on its website on Monday, the Communist Party of China Central Commission for Discipline Inspection said some people think the campaign cannot last for long, while others have suggested it has achieved its goal and should now be stopped.

"We must firmly oppose such notions and should never overlook the danger of their becoming popular among the public," the article said.
