A statement released after the meeting described the 18th CPC National Congress, held here from November 8 to 14, as "an extremely important meeting convened at the decisive stage of completing the building of a moderately prosperous society in all respects."
The statement said that the foremost political task is to focus the minds of the Party, the nation and people on the congress's spirit and meet the various tasks and goals that have been set forth in the congress.
The newly-amended CPC Constitution reflects the fruit of the Party's theoretical innovation and development of experimentation, important theories and views, guidelines and policies aimed at improving the CPC leadership and strengthening Party building, the statement said.
The CPC, the world's largest political party with a reported membership of 83 million, has ruled China since its founding in 1949. The CPC unveiled a new leadership lineup led by Xi, 59, yesterday at the end of the 18th Party Congress.
Xi replaced Hu Jintao, 69, who retired after serving as the General Secretary of the CPC for 10 years.
