Increased Vietnamese involvement in Laotian affairs
5 September 1945. Prince Phetsarath is contacted by his half-brother, Prince Souphanouvong, who for the last 16 years has been working as a civil engineer in Vietnam. Souphanouvong explains he is in Hanoi negotiating Vietnamese support for the Lao independence struggle. The viceroy rejects the overture; he has long held anti-Vietnamese views and is already concerned about Viet Kieu involvement in the nationalist movement. Indeed, only days earlier Viet Minh-allied forces in Thakhek organized local youth into armed units to oppose the French. These Lao–Viet units will become the model for future joint Lao Issara and Viet Minh collaboration.
