Laos is a landlocked country in Southeast Asia and the thickly forested landscape consists mostly of rugged mountains, the highest of which is Phou Bia  at 9,242 feet (2,817 m), with some plains and plateaus. The Mekong River forms a large part of the western boundary with Thailand, whereas the mountains of the Annamite Chain form most of the eastern border with Vietnam.
