Cambodia’s transport system was seriously damaged by war and continuing fighting. Nowadays, thanks to the assistance from the outsides like the Asian Development Bank (ABD), neighbor countries, etc, Cambodian infrastructure of transport has been positively improved. Almost the main highways in the country are upgraded and paved. Cambodian government’s target is developing a transport system which can match international standards and expending highway lines to neighbor countries in the region. Inland waterways on Mekong and Tonle Sap River also play an important role in national transport. Moreover, Cambodia’s transport now comprises several kinds of transportation such as plane & helicopter, bus, train, car & taxi, motorcycle & cycle, and boat. Especially, there are some unique sorts of vehicle like bamboo-train, cyclo, sampan, river cruise, etc.
