A similar identity issue exists in the United States, where conflicts have arisen among Chinese-speakers due to a large recent influx of Mandarin-speakers. While older Taiwanese immigrants have learned Cantonese to foster integration within the traditional Chinese American populations, more recent arrivals from the Mainland continue to use Mandarin exclusively. This has contributed to a segregation of communities based on linguistic cleavage. In particular, some Chinese Americans (including American-born Chinese) of Cantonese background emphasise their non-Mainland origins (e.g. Hong Kong, Macau, Vietnam, etc.) to assert their identity in the face of new waves of immigration.
