A quick glance at Tuva specifically on Wiki has an extremely short period of time in Russia’s political sphere. I’m not sure if the predominately Buddhist parts of Russia have that deep of a Russian history.
Well, just look at any US area, and you'll notice an extremely short USA history, compared to the Native American history and population. And yet, not a single person in the USA talks about Native Americans claiming back their historical and cultural territories. Why? The only reason that comes to mind is Native Americans being effectively extinguished by the USA, while Buddhists/Mongols in Russia are integrated and accepted as a part of the society.
