The issue of black migration offers to the historical science a rich and varied field of study. Thus, the black identification in the continents other than Africa has often been exclusively attributed to slavery and the slave trafficking. Yet, these two facts of history were only a phase of the migration process initially from antiquity. This work scorches the origin of black presence in Asia and the main question is that, how blacks found themselves in ancient China on point to participate in the writing of the history of this country? In historical and critical approach that focuses on interdisciplinary, we propose in this reflection to identify the trace of the black migration in ancient China and to show the basis of several determinants, the historical role of blacks in the standing of current China. Based on the exploitation of various work on the issue, and the use of several sources, the consensual point is that the African continent as the starting position of this stand. It appears that the black of African origins have inhabited ancient China before the XVth century.
