History of the Khmu:

     The Khmu, or also known as Khamu or Kammu, are a subdivision of the greater Khmuic peoples and are known as being the first to settle into the Indo-China Peninsular around 40,000 B.C. To define the Khmu and its people, they are Austro-Asiatic people and believed to of resided in what is currently known as the Peoples Republic of China all the way to their destination of origin, Indo-China Peninsula. The people of Laos, where most Khmu are currently present, refer to the Khmu as Kah, Austro-Asiatic people, which has a central meaning of slave. They are also referred to as the hill people within the same region using the name Lao Theung and known as the first indigenous people of Laos. However,in the Peoples Republic of China they are placed under the category of undistinguished ethnic groups due to the fact that they are not recognized officially as a separate ethnic group. http://en.wikipedia.org/wiki/Khmu_people
