In the ensuing power vacuum, Phetsarath moved to unite the southern provinces of Laos with Luang Phrabang. This put him at odds with the pro-French King Sisavang Vong, who had agreed with the French that he intended to have the country resume its former status as a French colony. Phetsarath sent a telegram to all Laotian provincial governors notifying them that the Japanese surrender did not affect Laos' status as independent and warning them to resist any foreign intervention. On 15 September Phetsarath declared a unified Kingdom of Laos which led the King to dismiss him from his post as Prime Minister on 10 October.
