Vietnam has an area of 127,207 square miles (329,465 square kilometers) and is located in Southeast Asia. The country has a coastline of nearly 1,440 miles (2,317 kilometers), much of which fronts on the South China Sea. Border countries are China, Cambodia, and Laos.

The major lowland area is a delta that has been created by deposits from the Red River as it enters the Gulf of Tonkin. The river passes through the capital city of Hanoi. For more than 2,000 years the Tonkin Lowland, considered the cradle of Vietnamese civilization, has been the scene of considerable water control efforts in the form of canals and dikes.
The southernmost portion of the country is dominated by another lowland that is much more extensive than that in the north. This lowland has essentially been created by the Mekong River (Song Cuu Long) and its various tributaries. Just north of Ho Chi Minh City (formerly Saigon) the landscape becomes more varied and rolling with forested hills.
The central portion of Vietnam varies in width but is only 35 miles (56 kilometers) at its narrowest point. This region has only...
