This paper is based on the background of many Chinese immigrants to Singapore in recent years. Singapore is a multicultural country. The Chinese identity in Singapore is also influenced by multiple factors such as history and culture. This paper studies the causes and status quo of the identity dilemma of the Chinese in Singapore, which provides a reference for China's research in this field and promotes the development of China-Singapore relations. This study is based on the intercultural communication theory and the consultative identity theory, using case analysis to draw the conclusion that the current Singaporean Chinese are faced with a dilemma in the identity process, and put forward suggestions on this phenomenon: Singaporean Chinese should actively negotiate to carry out innovative development on the basis of protecting the fundamental development of identity culture. Understanding and helping Singaporean Chinese to form an identity and value system is conducive to promoting the positive development of China-Singapore relations under the background of globalization.
