He said the Party must remain committed to a people-centered philosophy of development and make steady progress toward enhancing the people's sense of fulfillment and realizing common prosperity for everyone.

The CPC will mark its centenary in 2021.

Xi said the Party will generate waves of positive energy which can build into a mighty and nationwide force driving China's development and progress.

"For a party which fights for the eternal wellbeing of the Chinese nation, the centenary only ushers in the prime of life," Xi said. "As the world's largest political party, the CPC must behave in a way commensurate with this status."

Xi said China will work with other nations to build a global community with a shared future, and make new and greater contributions to the noble cause of peace and development for all humanity.

He said the 19th Party Congress has received extensive and detailed reporting and the media coverage has captured the attention of the world.

A total of 452 major political parties in 165 countries have sent 855 messages of congratulation to the CPC on the congress.

Xi encouraged the press to continue to follow China's development and progress, and learn about and report on more dimensions of China.

"We do not need lavish praise from others, however, we do welcome objective reporting and constructive suggestions, for this is our motto: 'Not angling for compliments, I would be content that my integrity fills the universe,'" Xi said.
