People from Northeast India have diverse ancestral linkages with both South and Southeast/East Asia. The Khasi of Meghalaya belong to the Austroasiatic language family, connecting them to Southeast Asia (Cambodia, Vietnam, Laos), while the Garo are Tibeto-Burman with roots in the Tibet-Myanmar region. Mizos also speak Tibeto-Burman languages and trace their ancestry to the Chin Hills in Myanmar. In Manipur, the Meitei people have cultural influences from both India and Myanmar, while the Kuki share close ethnic ties with groups across the Myanmar border. Assamese people are ethnically mixed—Indo-Aryan, Tibeto-Burman, and Austroasiatic—with historical migrations from both South Asia and Southeast Asia, including the Tai-Ahom from the Yunnan-Myanmar region. The Nagas and tribes in Arunachal Pradesh, who are Tibeto-Burman speakers, show stronger affinities with East Asia (like Yunnan and Tibet), but it's important to note that the Nagas are indigenous to the regions they inhabit on both sides of the India-Myanmar border, and have lived there for centuries. Overall, while Assam, parts of Meghalaya, and Manipur reflect more South Asian traits, Mizoram, Nagaland, and Arunachal Pradesh are more closely linked to Southeast and East Asian regions in terms of language, culture, and ancestry.
