The Communist Party of China (CPC) will generate waves of positive energy which can build into a mighty and nationwide force driving China's development and progress, said Xi Jinping, general secretary of the CPC Central Committee on Wednesday.

"We must continue to rid ourselves of any virus that erodes the Party's fabric, make great efforts to foster a healthy political environment of integrity, and generate waves of positive energy throughout our Party," Xi said while meeting the press at the Great Hall of the People.

The CPC will mark its centenary in 2021.

"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."
