The eviction of Chinese cotton farmers from Mexicali, Baja California serves as a focal point to explore the racial boundaries of dominant discourses of Mexican national identity. By examining the politics of agrarian reform, the article illustrates how the racial alterity of Chinese immigrants to national ideals served to consolidate diverse Mexican peoples as liberal mestizo racial subjects. Racial alterity is further explored by tracing the lives of Mexican women who married Chinese men and their multi-ethnic children. Anti-Chinese politics and conscription of mestizo subjects were central themes in the Mexicanization of Baja California.
