Xi is the first CCP General Secretary born after the establishment of the People's Republic of China. Since assuming power, Xi has introduced far-ranging measures to enforce party discipline and to impose internal unity. His anti-corruption campaign has led to the downfall of prominent incumbent and retired Communist Party officials, including a member of the Politburo Standing Committee. He has also enacted or promoted a more assertive foreign policy, particularly with regard to China–Japan relations, China's claims in the South China Sea, and its advocacy for free trade and globalization. He has sought to expand China's African and Eurasian influence through the Belt and Road Initiative.
