Bordering on Laos by the Mekong River, Chiang Khan in northern Loei province of Isan (northeastern Thailand located on Khorat Plateau) is a sparsely-populated district. Two main roads in the district center spanning around 2 km and running parallel to the River are connected by more than 20 inner streets, with rows of one- or two-storey houses stand on the waysides.
