In ethnogeography, Greater China is a loosely-defined term that refers to the region sharing cultural and economic ties with the Chinese people, often used by international enterprises or organisations in unofficial usage.

[1][2][3][4][failed verification] The notion contains a "great deal of ambiguity in its geographical coverage and politico-economic implications",[5] 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".

The term's usage is contested; some observers in Taiwan characterise the term as harmful or a conflation of distinct polities and markets,[4] while the Chinese government has avoided it, either to allay fears of its economic expansionism or to avoid suggesting Taiwan (known as the Republic of China) and the People's Republic of China are on equal footing.

During the 1930s, George Cressey, an American academic who did work for the US State Department throughout his career, used the term to refer to the entirety of the territory controlled by the Qing dynasty, as opposed to China proper.

[19] The English term subsequently re-emerged in the 1980s to refer to the growing economic ties between the regions as well as the possibility of political unification.
