BEIJING, Jan. 3 (Xinhua) -- The discipline watchdog of the Communist Party of China (CPC) has made more efforts for discipline violation reviews.

More emphasis has been given to reviewing breaches of political and organizational discipline by officials to enhance political awareness and ensure officials' thoughts, politics and acts remain in line with the CPC Central Committee, said an official in charge of handling discipline violation cases with the CPC Central Commission for Discipline Inspection (CCDI).

According to the CCDI, 33 of 77 cases closed in 2016 involving centrally administered officials involved breaches of political discipline, including disloyalty and dishonesty to the Party, failing to report personal matters as required, and concealing facts during inquiries.

Other violations, such as wavering Party ideals and beliefs, political conspiracies through forming cliques to pursue selfish interests, and superstition have also been seen in discipline checks nationwide.

In the first half of 2016, 29,000 Chinese officials confessed their discipline violations to the authorities, more than five times the figure in 2015.

From January to November last year, the CCDI made over 1,300 inquiries through interviews or letters after being tipped off about breaches of discipline by centrally administered officials, a year-on-year increase of 96.5 percent.

During the same period, discipline agencies at all levels made 111,000 inquiries, more than triple that in 2015.

Among the 77 cases of centrally administered officials, 20 were investigated for suspected illegal activity, while officials involved in the other cases were subjected to disciplinary penalties or demoted.
