Under the background of globalization , the national identity and cultural identity held by overseas Chinese are closely related to the population distribution and the professions they are in , the policy evolution and thecurrent policy of the residence countries ,and the reactions on the part of resident Chinese as well . Generally , if a country takes drastic policies toward Chinese , which may take the form of″racial great wall″a iming toisolate Chinese by setting restrictions on their religion and residence , the overseas Chinese usually find it hard to integrate into and be identified with that country .In some extreme cases ,overseas Chinese would stick to the identity of their motherland and cultures . On the contrary , in the countries adopting inclusive policies , the Chinese will most probably integrate themselves into the local society and gain easy access to the nationality . However , there is one thing in common—even if the overseas Chinese have acquired the nationality of the country of residence , they would still preserve their cultural identity of Chinese , which is particularly true among the Hakkas , one of the subgroups of Han nationality .
