BEIJING -- "No prohibited zone or exception will be allowed in intra-Party supervision," according to a communique released Thursday after a key meeting of the Communist Party of China (CPC).

Intra-Party supervision should be carried out in accordance with regulations and by observing the principles of democratic centralism, top-down organizational supervision, democratic supervision from the bottom to the top, and peer review or critique, said the communique released after the sixth plenary session of the 18th CPC Central Committee which runs from Monday to Thursday.

The mission of intra-Party supervision is to ensure the Party Constitution, its regulations and code of conduct are enforced effectively; to maintain Party unity and solidarity; and, primarily, to resolve Party leadership enervation and slackness in Party building and governance as well as discipline slackening, it said.

Supervision will ensure Party organizations perform their due duties, that all members play vanguard and exemplary roles and leading officials are loyal, clean and accountable.

The main targets of supervision are the CPC's top organs and officials, particularly senior officials, according to the communique.

Intra-Party supervision should focus on Party members' observance of the Party Constitution and rules as well as the country's Constitution and laws, adherence to the centralized and unified leadership of the CPC Central Committee, official's integrity and self-discipline, and impartial exercise of official power.

The CPC Central Committee, Political Bureau of the CPC Central Committee, and the Standing Committee of the Political Bureau of the CPC Central Committee should lead intra-Party supervision, according to the communique.
