While a number of more-established Taiwanese immigrants have learned Cantonese to foster relations with the traditional Cantonese-speaking Chinese American population, more recent arrivals and the larger number of mainland Chinese immigrants have largely continued to use Mandarin as the exclusive variety of Chinese. This has led to a linguistic discrimination that has also contributed to social conflicts between the two sides, with a growing number of Chinese Americans (including American-born Chinese) of Cantonese background defending the historic Chinese-American culture against the impacts of increasing Mandarin-speaking new arrivals.
