BEIJING, Oct. 2 -- An article by Xi Jinping, general secretary of the Communist Party of China (CPC) Central Committee, on Party building, was published Tuesday in the 19th issue of the Qiushi Journal this year.

The article by Xi, also Chinese president and chairman of the Central Military Commission, called for persistent efforts in this regard.

"Our Party must have the courage to carry out self-reform to make the Party stronger," the article said.

It also required strict self-governance of the Party.

Noting the unprecedented new challenges and new requirements facing the CPC, as well as factors undermining the Party's advanced nature and purity, the article called for consolidation and innovation in Party building and the spirit for complete self-reform.

It also underlined the importance of the "key few" in the Party, asking the Party's leading officials to observe the principle of "Three Stricts and Three Earnests."
