The human rights situation of Tibetans in the whole of the Tibetan Plateau is the same. Their economic marginalization is similar. The environmental destruction is similar. Even the Chinese government says that the Tibet Autonomous Region and other, adjacent Tibetan areas are all Tibetan autonomous prefectures and Tibetan autonomous counties. The Chinese government also called them “Tibetan autonomous areas”. Essentially, the Chinese government recognized them as the same Tibetan area. It's just that they have called them “Tibetan autonomous areas” and put them in different Chinese provinces.
