The 17th National Congress of the Chinese Communist Party was held in Beijing, China, at the Great Hall of the People from 15 to 21 October 2007. Congress marked a significant shift in the political direction of the country as CCP General Secretary Hu Jintao solidified his position of leadership. Hu's signature policy doctrine, the Scientific Development Concept, which aimed to create a "Socialist Harmonious Society" through egalitarian wealth distribution and concern for the country's less well-off, was enshrined into the Party Constitution. It was succeeded by the 18th National Congress of the Chinese Communist Party.

Hu Jintao is a Chinese retired politician who served as the general secretary of the Chinese Communist Party (CCP) from 2002 to 2012, the president of China from 2003 to 2013, and chairman of the Central Military Commission (CMC) from 2004 to 2012. He was a member of the CCP Politburo Standing Committee, China's de facto top decision-making body, from 1992 to 2012. Hu was the fifth paramount leader of China from 2002 to 2012.
