BEIJING - The Communist Party of China (CPC)'s anti-graft watchdog exposed cases in which Party officials were held accountable for failing to stop graft or other disciplinary violations in their work units on Sunday.

A research institute affiliated to the Yangtze Waterway Bureau of the Ministry of Transport was criticized for organizing overseas trips with public funds and over-subsidizing their employees, a statement issued by the Central Commission for Discipline Inspection (CCDI) said.

For this "work style" violation, Xiong Xuebin, deputy chief of the Bureau's CPC committee and head of the bureau, was removed from his posts, and the former Party chief of the bureau, Li Weihong (retired) was publicly criticized.

In another case, Huang Yongyue, Party chief of Yongfu county in Guangxi Zhuang autonomous region, was sacked after the county government offered its employees a bonus totalling 2.089 million yuan ($334,000), which was against rules.

Xie Haisheng, Party chief of environment bureau of Xiamen city, in Fujian province, was sacked after several other officials in the bureau were caught engaged in bribery, according to the statement.

Five other cases were also included in the statement. It is the first time the CCDI publicly reported such cases in 2015.

The CCDI said some Party officials failed to stop or report corruption developing in their units, some turned a blind eye to the offenses and others went as far as covering up their units' wrongdoings, urging Party officials to take primary responsibility for work style revamp in their units.
