Wang Huning, also a member of the Standing Committee of the Political Bureau of the CPC Central Committee and head of the leading group of the campaign, delivered closing remarks.

The launch of the campaign is an urgent need for arming the whole Party with the thought on socialism with Chinese characteristics for a new era, advancing Party building in the new era, maintaining the Party's close ties with the people, as well as achieving the goals and accomplishing the tasks put forward at the 19th CPC National Congress, according to Xi.

The Party's fundamental purpose of whole-heartedly serving the people, and its historic mission of realizing national rejuvenation should be kept firmly in mind, he said.

Xi said the campaign should adhere to high standards and strict demands, push Party members to rectify and adjust themselves with a clear purpose, avoid the practice of formalities for formalities' sake and bureaucratism, and help solve major problems that the people are strongly concerned about.

The campaign will educate and guide all Party members and officials to deepen their understanding of the thought on socialism with Chinese characteristics for a new era and the major policies of the CPC Central Committee, as well as to strengthen their beliefs of Marxism and socialism with Chinese characteristics, he said.

Through the campaign, CPC members should foster perseverance, think what the people are thinking and work together with the people, he said, adding that the campaign also aims to resolutely prevent and crack down on corruption.

Xi called on the Party members and officials to better arm themselves with theory and have the courage to reform themselves.

All areas, departments and organizations should list the prominent problems that need to be addressed and make efforts to solve them, Xi said.

Noting the campaign is under the leadership of the Standing Committee of the Political Bureau of the CPC Central Committee, Xi asked Party committees and leading Party members groups at all levels to enhance supervision and guidance over the campaign.

The passion of Party members and officials unleashed by the campaign should be converted to achievements in their work, Xi said.
