Tai
The Tai ethnic minorities include the Thai, Lao, Shan, and the Kula. They remain in very small numbers scattered throughout the provinces of Cambodia. Thai minorities mainly live in Phnom Penh while the Laotian people live in with the hill tribes to the north. Shan and Kula minorities reside in Pailin Province where their ancestors migrated to participate in the lucrative gem trade. The local Khmer dialect in Pailin has been noted to have been influenced by Burmese in tone and pronunciation from the ethnic minorities speaking it.
