BEIJING, Oct. 29 (Xinhua) -- The Communist Party of China (CPC) Central Committee had since 2012 "timely detected, decidedly handled, and resolutely eradicated" careerists and conspirators such as Zhou Yongkang, Sun Zhengcai and Ling Jihua, a report from the Party anti-graft body read.
It had defused "major political pitfalls" over the past five years, according to a work report of the 18th CPC Central Commission for Discipline Inspection (CCDI).
The report was submitted to the 19th CPC National Congress concluded earlier this week and published on Sunday.
In it, the CCDI said corruption is the biggest threat to the Party's rule.
"Interest groups formed by intertwining political corruption and economic corruption have severely undermined political security of the Party and the country," it read.
"Zhou Yongkang, Sun Zhengcai, Ling Jihua and others had seriously breached Party disciplines and political rules and, with ballooning political ambitions, resorted to conspiracy," the report continued.
But the CPC Central Committee "timely detected, decidedly handled, and resolutely eradicated" these careerists and conspirators and defused "major political pitfalls."
The CCDI, for its own part, ascertained their corruption problems, properly handled all people involved, and eliminated their pernicious influences, it said.
It also deeply analyzed the cases of Zhou Yongkang, Bo Xilai, Guo Boxiong, Xu Caihou, Sun Zhengcai and Ling Jihua, among others, and asked the whole Party to learn from their mistakes in order to affirm the Party's disciplines and protect the Party's unity, it said.
