This study focuses on the native identity of Chinese immigrants who have naturalized in Korea. The history of Chinese immigration to Korea spans over a hundred years, and today, Chinese residents form the largest immigrant community in Korean society. With the influx of Chinese immigrants, there are also many naturalized Chinese citizens in Korea. While most naturalized Chinese citizens in Korea are ethnic Koreans from China, there is also a significant number of non-Korean ethnic Chinese individuals. However, compared to ethnic Koreans, Chinese ethnic minorities in Korea receive less attention, and research on this particular group is scarce. Especially regarding their identity, there is a lack of research. Therefore, this study selects individuals of Chinese ethnic background as the research subjects. The researcher of this study is a Chinese international student. Shortly after coming to Korea for studies, they encountered strong anti-China sentiments in Korean society. Criticisms of China flooded the media and social media platforms. This piqued the researcher's curiosity about the impact of the anti-China sentiments in Korean society on Chinese individuals. This curiosity became the background for initiating this paper. The focus of interest shifted towards naturalized Chinese citizens in Korea. Unlike temporary Chinese residents or overseas Chinese who have not renounced their Chinese nationality, it was wondered whether Korean naturalized Chinese citizens would have a different sentiment towards Korea. While they choose to give up their Chinese citizenship and pursue a new life in Korean society, it was believed that Korea's strong anti-China sentiments would inevitably influence them in some way. Particularly, since research specifically on Chinese immigrants who have naturalized in Korea is scarce, the researcher's curiosity grew even stronger. Through research on Chinese immigrants who have naturalized in Korea, it is evident that they experience identity confusion during the early stages of naturalization. This confusion manifests as a dual identity. On one hand, despite changing their nationality, they continue to maintain their native identity. Moreover, they actively practice their Chinese identity in their daily lives. On the other hand, the current prevailing anti-China sentiments in Korea are influencing them. This study points out that due to discrimination and prejudice stemming from anti-China sentiments, their Chinese identity is further reinforced. This can be explained by the concept of Rejection-Identification, wherein members of a particular race or ethnic group, upon perceiving discrimination against that group, strengthen their group identity based on their membership.
