缅甸与泰国山地民族跨国分布格局的形成,是一个漫长的历史过程。孟人和拉佤人在泰语民族入主缅泰边境地区之前是当地至少是泰北地区的主要居民,克伦人也较早进入了该地区。随着拉祜、阿卡、傈僳、苗、瑶、克木、崩龙等民族的不断迁入,至20世纪80年代,缅泰山地民族的跨国分布格局最终形成。 The formation of cross-border distribution pattern of ethnic groups in Myanmar and Thailand is a long historical process. Before the Thai people joined the Thai-Burmese border area, the people of Meng and La Wa were the main inhabitants of at least the northern part of Thailand. Karen people also entered the area earlier. With the constant immigration of ethnic groups such as Lahu, Acre, Sunda, Miao, Yao, Kemu and Panglong, the transnational distribution pattern of the ethnic groups in Myanmar and Taishan Mountains came into being in the 1980s.
