In Xi Jinping's first term, he did not do that much, but as soon as he stabilized his second term, he dramatically increased this high nationalism combined with the domination of the Communist Party, which was increasingly put into the curriculum. That's one example.
The other concrete example I can give you is that in 2015, when I was sitting with Chinese scholars, they would say, “We can give generous autonomy to the TR, but the entire Tibetan region is too big.” At the time we could talk about this, but in 2018, those Chinese scholars started detaching themselves from these long-term friendships with Tibetan scholars and other minority scholars. The entire social atmosphere was turned into high nationalism in society.
