Little China refers to a politico-cultural ideology and phenomenon in which various Japanese, Korean and Vietnamese regimes identified themselves as the "Central State" and regarded themselves to be legitimate successors to the Chinese civilization. Informed by the traditional Chinese concepts of Sinocentrism and Sino–barbarian dichotomy, this belief became more apparent after the Manchu-led Qing dynasty had superseded the Han-led Ming dynasty in China proper, as Tokugawa Japan, Joseon Korea and Nguyễn Vietnam, among others, perceived that "barbarians" had ruined the center of world civilization.
