Corruption is the biggest threat to China's Communist Party, President Xi Jinping said on Monday, in a clear warning that the ruling party is resolved to tackle a long-running problem that is now entrenched in many strata of Chinese society.

More than 200 specialized detention facilities have been built or expanded across China, a CNN investigation finds, as the Chinese leader extends his crackdown beyond the ruling Communist Party to a vast swath of public sectors.

Anti-corruption campaign brings down senior health officials, hospital directors, academics, and pharmaceutical company executives.

Even the lowly 'flies' and 'ants' in China's vast bureaucracy will not be spared in the corruption fight, a state broadcaster television program showed Sunday.
