Hu Jintao (Pinyin: Hú Jǐntāo, pronounced [xǔ tɕìntʰɑ́ʊ]; born 21 December 1942) is the current Paramount leader of the People's Republic of China. He has held the titles of General Secretary of the Communist Party of China since 2002, President of the People's Republic of China since 2003, and Chairman of the Central Military Commission since 2004, succeeding Jiang Zemin as the chief of the fourth generation of leadership of the Communist Party of China.

Hu has been involved in the Communist party bureaucracy for most of his adult life, notably as Party secretary for Guizhou province and the Tibet Autonomous Region, and then later first Secretary of the CPC Secretariat and Vice-President under former leader Jiang Zemin. Hu is the first leader of the Communist Party without any significant revolutionary credentials. As such, his rise to the presidency represented China's transition of leadership from establishment communists to younger, more pragmatic technocrats.

During his term in office, Hu has reintroduced state control in some sectors of the economy that were relaxed by the previous administration, and has been conservative with political reforms. Along with his colleague, Premier Wen Jiabao, Hu presided over nearly a decade of consistent economic growth and development that cemented China as a major world power. He sought to improve socio-economic equality domestically through the Scientific Development Concept, which aimed to build a "Harmonious Society" that was prosperous and free of social conflict. Meanwhile, Hu kept a tight lid on China politically, cracking down on social disturbances, ethnic minority protests, and dissident figures. In foreign policy, Hu advocated for "China's peaceful development", pursuing soft power in international relations and a business-oriented approach to diplomacy. Through Hu's tenure, China's influence in Africa, Latin America, and other developing countries has increased.
