How to combine geopolitics with Chinese frontier studies seems to be the correct way out for the principle of Chinese frontier studies. Besides social system, industrialization degree, national composition and historical identity, geo-organism is another important factor that determines the state construction form. This paper attempts to explain the different functions of geographical pattern before and after industrial civilization through the brilliant history of Angkor Dynasty in Cambodia. For example, the landform surrounded by mountains on three sides and going out to sea in the southwest makes it possible to build large-scale water conservancy facilities, which in turn contributes to the largest rice producing area in the Indochina Peninsula. Another example is that the unique waterway channel opens the gate of military and material transportation, which facilitates the expansion of production and military occupation. These are enough to prove the relationship between the state form and the geographical organism, and put forward new ideas for exploring the principles of China’s frontier science, and also provide useful historical reference for strengthening regional cooperation along route of the Belt and Road Initiative and building Community of Shared Future for Mankind.
