Actually, thinking about it a bit more, I'd bet my money (but of course, pure speculation) that China would continue to take a path of minimizing risk, with little concerns for so-called "human rights". So, the same treatment the Uyghurs are currently getting I expect would eventually be applied to all groups that could be plausibly considered to be non-conforming. Considering the typically independent thinking personality of a lot of Westerners, I expect we would eventually be in for a bit of that ourselves. Whether some old scores are settled (Japan) is another wildcard.
Of course, all of this is not only speculation, but a work in progress - even if I do turn out to be mostly right, it is all subject to a combination of which particular person is running the show in China at the time, the general nature of Chinese culture (including how that changes over time as things progress), as well as whether there are complications in terms of pushback or natural disasters. So....who knows. But a lack of certainty in no way means risk management is a completely pointless exercise...if we'd been doing any for the last 20 years, we needn't have ended up in this current predicament where we hold very few of the cards, and any path we choose almost certainly comes with massive pain.
This Canadian youtuber has some interesting commentary on the matter now and then:
The 2:40 point where he opines on China's approach to the Uyghurs is very interesting. Trigger warning: it is not quite compliant with the "facts of the matter" as dictated to us by all right thinking Western institutions.
I like watching these sorts of opinions on YouTube from people that actually know something about the world, rather than spending all their time in a classroom or TV studio, it shows how silly the "facts" of how we "should behave" are, and how it's just a bunch of largely empty ideology that's been drilled into Western people's heads through several vectors over decades. Chinese people have been subject to propaganda as well, but a completely different kind than us. We've been told ad naseum that all cultures think like us, and want the same things we do, but it simply isn't true. Going into battle for superpower status of the world with a head full of utterly delusional ideas doesn't seem like a winning strategy to me, but then maybe I need some more schooling.
