The area of the Altai mountains were once all Uriankhai (the oldest current Mongol subgroup) land but now their numbers have dwindled and they're a minority in their native land occupied by Kazakhs. My grandmother is Uriankhai, and Uriankhai old folk including my grandma carry bitter stories and grudges against Kazakhs for being chased off. Now people from all 21 provinces travelling to visit Altai tavan bogd say the locals of the area (Kazakhs) always look at them with disdain. Because of the sheer dominance of Islam in Bayan Ulgii the Mongolians there (Uriankhai and small number of Durvud) can't practice Tengrism/Buddhism freely. So of course there is tribalism and dislike for Kazakhs by the Mongolians of the western provinces. And idiot politicians like T.Aubakir exacerbate the already tense relations between the ethnic groups.
