Kou Voravong
In June 1958, the "Committee for the Defense of National Interests" was created in Vientiane. Its program was the eviction of communist ministers of the "Lao Neo Hak Sat" party (ແນວລາວຮັກຊາດ), and the overthrow of the neutralist Government, in order to maintain Laos in the United States orbit. This civic association of young Laotians, anti-communist and renovator, was led by the army strongman, the general Phoumi Nosavan. Born in the Thai-Lao region border (Moukdahane-Savannakhet), he was the nephew of Sarit Thanarat (thai: สฤษดิ์ ธนะรัชต์) – the current Thai Government Prime minister – and first of all, the general Phoumi Nosavan was Kou Voravong's cousin and brother-in-law.
