China has been a popular research subject in the past few decades, while the way to view China has witnessed dramatic changes. This research holds that it is important to systematically study the relationships between China studies and the social, economic and political forces guiding through analyzing the analytical angles selected by scholars have an impact upon how they perceive China. In the China studies communities, the ethnic Chinese scholars¡¦ knowledge of China in Southeast Asian is a noteworthy example: their identities imply diverse degree of Chinese history and cultural inheritance. The variety of ethnic Chinese identities represents the different epistemology of China. This research aims to add to the¡§Epistemology of China Studies¡¨ project by exploring the perspective of ethnic Chinese interpretation of China through Prof. Leo Suryadinata, who perceives China from a distant, yet culturally connected viewpoint. Through the sociology of knowledge approach, we could understand Leo Suryadina¡¦s China interpretation which involves an alien emotion in his academic and literature works, and also from the Southeast Asian Chinese society where he locates in. In Leo Suryadina¡¦s epistemology of China, China is an alien homeland and an object as he interprets it. On the other hand, as Leo Suryadinata¡¦s interpretational tool, China is a concept of ethnic Chinese identities with redefinition.
