He said the new Central Committee has brought together leading members and outstanding representatives of the Party from various regions, departments, spheres and sectors.

It is a broadly representative and well-structured body with highly qualified members who meet the standards for Central Committee membership, match the expectations of ordinary officials and the general public, and reflect the realities of the Party's leadership teams and officials, he said.

"They will definitely be capable of shouldering the historic mission of rallying and leading the whole Party, the entire military, and the Chinese people of all ethnic groups in building a modern socialist country in all respects and advancing national rejuvenation on all fronts," he said.

He called on the delegates to the congress to firmly keep in mind the Party's original aspiration and founding mission, saying that they should study, observe, implement and uphold the Party Constitution with a stronger sense of purpose, and closely follow the Central Committee in thinking, political stance and action.

"We must firmly keep in mind that this country is its people, the people are the country. We must fulfill our fundamental purpose of serving the people wholeheartedly, maintain a close bond with the people, and always stand on their side, empathize with them, and work alongside them," he said.

He continued: "We must contribute all of our wisdom and energy to the cause of the Party and the country, set a good example for other Party members, and prove ourselves fully worthy of the trust they have placed in us."

Xi said the CPC is still in its prime more than 100 years on from its founding, adding that "we are fully confident and capable of creating new and even greater miracles on the new journey of the new era, miracles that will amaze the world".

He also expressed appreciation, on behalf of the presidium of the congress, to the central committees of non-CPC political parties, the All-China Federation of Industry and Commerce, and public figures from all ethnic groups and all sectors in China, as well as political parties and organizations from many countries.
