"Greater China" is a term describing a geographical area sharing cultural and economic ties with the Chinese people. The notion contains a "great deal of ambiguity in its geographical coverage and politico-economic implications", because some users use it to refer to "the commercial ties among ethnic Chinese, whereas others are more interested in cultural interactions, and still others in the prospects for political reunification" but usually refers to an area encompassing the People's Republic of China and Taiwan, places where the majority population is culturally Chinese. Some analysts may also include places which have predominantly ethnic Chinese population such as Singapore. The term may sometimes be generalised to encompass "linkages among regional Chinese communities".

The Chinese people, or simply Chinese, are people or ethnic groups identified with China, usually through ethnicity, nationality, citizenship, or other affiliation.
