'''Vientiane''' ( , ; , ) is the capital and largest city of Laos, on the banks of the Mekong River near the border with Thailand. Vientiane became the capital in 1573, due to fears of a Burmese invasion, but was later looted, then razed to the ground in 1827 by the Siamese (Thai). Vientiane was the administrative capital during French rule and, due to economic growth in recent times, is now the economic center of Laos. The city had a population of 948,477 as of the 2020 Census.
