It is not found any previous study on the Cham traders and the trade routes from the Central Coast to the Highlands of Vietnam. Taken just few scattered and related ancient documents, the authors have conducted some field surveys and researches of the local ethnic groups in the Highlands since 2013. Their moves aim at learning about the relationships and the trade routes connecting the Cham people and other ethnic minority people in the Central Highlands. The article is considered as one of the initial research outcomes. In this article, we identify the evidence of the Cham-Thuong relationships and their trade routes. It is the route along the main rivers, in parallel with the French-build railway in Highland and plenty of roads explored by both the minority people and Cham people through the historical periods.
