Zhū Róngjī (pinyin: Zhū Róngjī; Wade-Giles: Chu Jung-chi; IPA: [tʂú ʐʊ̌ŋtɕí]; born 23 October 1928 in Changsha, Hunan) is a prominent Chinese politician who served as the Mayor and Party chief in Shanghai between 1987 and 1991, before serving as Vice-Premier and then the fifth Premier of the People's Republic of China from March 1998 to March 2003.

A tough administrator, his time in office saw the continued double-digit growth of the Chinese economy and China's increased assertiveness in international affairs. Known to be engaged in a testy relationship with General Secretary Jiang Zemin, under whom he served, Zhu provided a novel pragmatism and strong work ethic in the government and party leadership increasingly infested by corruption, and as a result gained great popularity with the Chinese public. His opponents, however, charge that Zhu's tough and pragmatic stance on policy was unrealistic and unnecessary, and many of his promises were left unfulfilled. Zhu retired in 2003, and has not been a public figure since. Premier Zhu was also widely known for his charisma and tasteful humour.

Xi Jinping (pronounced [ɕǐ tɕînpʰǐŋ] English approx.:SHEE JIN PING; born 1 June 1953) is a high-ranking politician of the People's Republic of China. He currently serves as the top-ranked member of the Central Secretariat of the Communist Party of China, the country's Vice President, Vice-Chairman of the Central Military Commission, President of the Central Party School and the 6th ranked member of the CPC Politburo Standing Committee, China's de facto top power organ.

Son of communist veteran Xi Zhongxun, Xi Jinping served mostly in Fujian province in his early career. He was later appointed party chief of the neighboring Zhejiang province, and then was appointed as Shanghai's party chief following the dismissal of Chen Liangyu. Known for his tough stance on corruption and a frank openness about political and market economy reforms, Xi's combination of positions makes him the presumptive heir to current General Secretary and President Hu Jintao and the Paramount leader of the Communist Party of China's fifth generation of leadership.

Jiang Zemin (born 17 August 1926) is a former Chinese politician, who served as General Secretary of the Communist Party of China from 1989 to 2002, as President of the People's Republic of China from 1993 to 2003, and as Chairman of the Central Military Commission from 1989 to 2005. His long career and political prominence have led to him being described as the "core of the third generation" of Communist Party leaders.

Jiang Zemin came to power following Tiananmen Square protests of 1989, replacing Zhao Ziyang as CPC General Secretary. With the waning influence of Deng Xiaoping and the other members of Eight Elders due to old age,and with the help of old and powerful party and state leaders, former President Li Xiannian and Chen Yun Jiang effectively became the "Paramount Leader" in the 1990s. Under his leadership, China experienced substantial developmental growth with reforms, saw the peaceful return of Hong Kong from the United Kingdom and Macau from Portugal, and improved its relations with the outside world while the Communist Party maintained its tight control over the government. Jiang has been criticized for being too concerned about his personal image at home, and too conciliatory towards Russia and the United States abroad.
