Champa's southern border from the 13th to 17th centuries

Abstract

In the process of researching the history of Champa and Cambodia before the 17th century, a question arose, where was the borderline between the two? Historical sources, especially the Western ones, show that the border between Champa and Cambodia is different from today's understanding. This paper, by examining various sources, aims to identify the borderline between these two countries. The initial research results of this research suggest further in-depth research on the issue.
