Патет Лао
After the Battle of Vientiane in December 1960 and the subsequent retreat of Neutralist forces to the Plain of Jars, Phoumi was instrumental in arranging for Pathet Lao-Neutralist collaboration. He led the Pathet Lao delegation to the Geneva Conference on the neutrality of Laos in 1962, and served as Minister of Information, Propaganda and Tourism in the Second Coalition government. In 1964, after a series of political assassinations, Phoumi left Vientiane with other Pathet Lao ministers.
