At the end of the war, as the Communists succeeded in gaining power through the Provisional Government of the National Union, Kham Ouane Boupha was appointed Deputy Minister of Defense on April 9, 1974.
The Patriotic Neutralists movement that Kham Ouane Boupha headed was an indirect result of the 1960 coup led by Captain Kong Le.
Kong Le would subsequently lose both the Battle of Vientiane and control of Laos in December 1960 to General Phoumi Nosavan, and retreat to the Plain of Jars.
[3] Because he was considered competent,[4] Kham Ouane Boupha was appointed to the dual posts of governor and Military Region commander in Phongsali Province in either November 1957[3] or January 1958.
[6] On January 9, Brigadier General Kham Ouane offered to march on Luang Prabang and oust Kong Le's Forces Armee Neutraliste.
[7] Nevertheless, when a garrison from all parties to the Laotian Civil War was agreed upon in Luang Prabang, a company from BV 11 was flown in from Boun Neua.
[9] Prime Minister Souvanna Phouma struck a deal with the People's Republic of China, allowing the Chinese to build roads within Laos.
[11] On April 9, 1974, Kham Ouane Boupha was named Deputy Minister of Defense in the newly formed Provisional Government of the National Union.
[citation needed] In accordance with the new government's directives, U.S. personnel were drawn down to a 45-person Defense Attaché Office supplying the Royal Lao Army.
As Minister, he promptly halted Royalist troop movements as part of ending the Laotian Civil War and required them to pledge loyalty to the PGNU.
[18] On December 3, 2012, the Bureau of Human Resources of the Lao People's Revolutionary Party rewarded Kham Ouane Boupha's service with a housing award of 400 million kips.
