It starts with the Muslims because they can semi-credibly use the threat of Islamic Extremists as justification for the population control measures. Note the minimal backlash from world leaders outside reports in UK journals. However, this is should be a wake up call for what is coming next, in fact it has already started with their online monitoring and ongoing assessments to their citizens resulting in a social rating based on how well they conform to "correct thinking." The dictator Xi is scared to death of internal unrest, and is taking extreme measures to suppress it. After the Uighurs it will be Hong Kong, University campuses will become indoctrination centers (not unlike the U.S.), etc.. The technologies and tactics that enable this oppression will be exported to other countries that seek similar control. Most likely to countries where Xi has bought off the leaders and needs them to stay in power so he can exploit the country for economic gain.

We ignored this threat too long, it is a form of political extremism not unlike Nazism, or Maoism enabled by state controlled capitalism. The oppression of the Muslims was the first wave, we're watching the second wave of oppression build (social credit system), and we need to anticipate what the third wave will be.
