A top magazine of China's ruling Communist Party lashed out at critics of its ongoing anti-corruption campaign, saying foreign media and individuals from home and abroad were intentionally trying to discredit the effort as a political "power struggle."

Chinese President Xi Jinping has pursued a sweeping campaign to root out corruption since assuming power about three years ago, and has promised to strike hard at both senior and low-level officials, the "tigers" and "flies."

Nonetheless, there has been persistent speculation that the graft crackdown is also about Xi taking down his rivals.
