The Lao Development Association was a political party in Laos.
The party began as the Southern Bloc, a conservative group led by Leuam Insisiengmai and Boun Oum, and won 15 seats in the 1965 elections, emerging as the largest party.[1] Once in parliament, it formed the core of the Group of Thirty-Three.[2]
The Group of Thirty-Three helped vote down the 1966 budget,[2] leading to early elections in 1967. Following the elections the party was renamed the Lao Development Association. It was heavily defeated in the 1972 elections.[2]
