Sinicization, sinicisation, sinofication, or sinification, , also called chinalization , is a process whereby non-Han Chinese societies come under the influence of Han Chinese state and society. Areas of influence include alphabet, diet, economics, industry, language, law, lifestyle, politics, religion, sartorial choices, technology, culture, and cultural values. More broadly, "Sinicization" may refer to policies of acculturation, assimilation, or cultural imperialism of neighbouring cultures to China, depending on historical political relations. This is reflected in the histories of Korea, Vietnam, Taiwan and Japan in the East Asian cultural sphere, for example, in the adoption of the Chinese writing system.
