In the global ideological movements of the early twentieth century, notably communism, new political concepts moved across different cultures. Together with the process of internationalization, this led to problems concerning the translation and interpretation of linguistic terms. Based on little-studied sources deposited in the Comintern archive in Moscow, this article shows that, although the members of the newly formed Malayan Communist Party (1930) were virtually all Chinese, it became the first organization to discuss directly the possibility of a multi-ethnic Malayan nation within the borders of the Malay Peninsula. As the Comintern encouraged the establishment of ‘national’ communist parties, the ambiguity of the Chinese word minzu resulted in the emergence of a discourse regarding the Malayan ‘nation’, which would be liberated from colonialism under communist leadership.
