Senior officials should remain loyal to the Party and willingly safeguard the authority of the Party's central leadership and the unity of the Party, said the communique issued after the key plenum.

The Party's leading position should be ensured in all aspects and its role of overseeing all work and coordinating all parties should be guaranteed.

The Party principles should be upheld and its policies implemented, the document stressed.

All local authorities and departments should carry out the decisions of the CPC Central Committee in the first instance, it said.

Senior cadres should set an example for all Party members to keep the Party and the people at heart and be keenly aware of what should and should not be done.

They should display strong political and moral integrity, obedience to Party disciplines and resistance to corruption, the document said.

Being a party of more than 89 million members and the ruling party leading more than 1.3 billion people in the drive for reform and modernization, without the authority and centralized leadership of the CPC Central Committee and without strict political disciplines, rules and a clean political environment, the CPC would compromise its creativity, cohesion and effectiveness, weaken the foundation and ability of its governance and fail its mission, the document said.

The document called on all Party members to firmly safeguard the authority of the Party leadership, follow its lead and stay in accordance with the CPC Central Committee with Xi Jinping at the core.

"CRUSHING MOMENTUM" CONSOLIDATED

China has gained and consolidated "crushing momentum" in its fight against corruption, read the communique, adjusting previous judgement made late last year at a Political Bureau meeting, which only stated that the fight "has gained crushing momentum."

Participants at the session looked back on the work of the 18th CCDI over the past five years, and agreed that discipline inspection commissions at all levels have fulfilled the duties endowed by the Party Constitution, and have comprehensively pushed forward the strict governance of the Party.

The discipline inspection commissions have been working hard to build a clean Party and fight against corruption, firmly upholding the eight-point frugality code, according to the communique.

The communique also stated that the commissions have made full use of their inspections, prioritizing discipline, and have deepened the reform of discipline inspection and the country's supervisory system.

Moreover, the commissions have built groups of cadres in discipline inspection and supervision that both the Party and the people can trust, while consistently improving the accountability system, uncompromisingly containing the spreading of corruption and purifying the political ecology within the CPC, the communique said.

The plenum endorsed a decision made by the Political Bureau to expel Sun Zhengcai and eleven other senior Party officials from the CPC.
