landform that separates vietnam from cambodia and laos
Geography of Cambodia Cambodia's low mountain ranges - representing the walls of the bowl - remain as the result of only rather recent substantial infrastructural development and economic exploitation - in particular in remote areas - formidably forested.[28] The country is fringed to the north by the Dangrek Mountains plateau, bordering Thailand and Laos, to the north-east by the Annamite Range, in the south-west by the Cardamom Mountains and in the South by the Elephant Mountains. Highlands to the north-east and to the east merge into the Central Highlands and the Mekong Delta lowlands of Vietnam.[29][30]
Siamese fighting fish This species is native to the Mekong basin of Laos, Cambodia, Vietnam and Thailand. The fish can be found in standing waters of canals, rice paddies and floodplains.[2] It is listed as Vulnerable by the IUCN.
