There has been some debate on whether historical Eurocentrism qualifies as "just another ethnocentrism", as it is found in most of the world's cultures, especially in cultures with imperial aspirations, as in the Sinocentrism in China; in the Empire of Japan (c. 1868-1945), or during the American Century. James M. Blaut (2000) argued that Eurocentrism indeed army beyond other ethnocentrisms, as the scale of European colonial expansion was historically unprecedented and resulted in the formation of a "colonizer's model of the world".[24]
