BEIJING, April 29  -- The disciplinary watchdog on Wednesday released the results of its recent round of inspections on its website.

The Communist Party of China's (CPC) Central Commission for Discipline Inspection (CCDI) carried out its third round of special inspection for 2014 from November to December, covering 13 state organizations, including the Ministry of Environmental Protection, Ministry of Culture, China State Shipbuilding Corp., China Unicom and Sinopec.

Inspectors found problems that harmed public interests for private benefits, violated the eight-point frugality rules, and malpractice, according to a CCDI statement.

Senior Party leaders in these units were deemed "weak" in fulfilling their responsibility to the building of a clean Party, according to the statement.

Details will be open to public supervision, it said.

Since the 18th CPC National Congress in 2012, a number of inspections have been launched across the country.
