Cambodia's boundaries in 1987 were for the most part based upon those recognized by France and by neighboring countries during the colonial period. The 800-kilometer boundary with Thailand, coincides with a natural feature, the watershed of the Dangrek Mountains, only in its northern sector. The 541-kilometer border with Laos and the 1,228-kilometer border with Vietnam result largely from French administrative decisions and do not follow major natural features. Border disputes have broken out in the past between Cambodia and Thailand as well as between, Cambodia and Vietnam.
