The Communist Party of China will fight against corruption with greater determination, courage and endeavor, as comprehensively and strictly governing the Party is never the end of a journey, a spokesman of the 19th CPC National Congress said on Tuesday.

The country has witnessed several serious and significant corruption cases in recent years, including Zhou Yongkang, Bo Xilai, Guo Boxiong, Xu Caihou, Sun Zhengcai and Ling Jihua, and they have been punished in accordance with the national laws and the Party's disciplines, according to Congress spokesman Tuo Zhen.

All the officials mentioned above were former members of the CPC Central Committee. "This means any Party member who violates the disciplines and laws will be punished, no matter how high his or her position is," Tuo said.

To fight corruption, the Party has strengthened its internal construction at the same time, he said, adding the Party formulated and revised 90 internal regulations over the past few years.

In addition, the Party increased its self-supervision, conducting 12 rounds of inspections on 277 Party organizations, and full coverage of central–level inspection has been achieved within the five-year term of the central committee for the first time, according to Tuo.

He said the selection of Party officials is and will be made strictly, "and we'll increase efforts to supervise the selection, making sure the selected officials are clean and highly-qualified," he added.
