China isn't so crude or bold as to just exterminate Uighurs in massive numbers. China is patient.
China denies it is doing anything wrong and doesn't even seem to care that its lies aren't believed:
The United States has described what is happening to the mostly Muslim Uyghurs as a genocide. Starting in 2016, China launched a campaign of repression, banning Muslim names, forbidding long beards. It transformed the vast Uyghur homeland of Xinjiang into one of the most sophisticated surveillance states in the world, bristling with police checkpoints and facial-recognition cameras. Then people began to disappear.
Students coming home on break found empty houses. Officials told them their parents had been “infected” by the virus of Islamic radicalism and needed to be quarantined and cured, according to documents obtained by The New York Times. Occasional stories began to emerge from the camps: high-pressure indoctrination classes; forced labor; physical and sexual abuse; a grinding out of Uyghur language, culture, and identity.
Satellite imagery says China is lying.
And if it takes generations to erase minorities with indoctrination, repression, compulsory lower birth rates, and Han migrants from the rest of China, China is fine with that.
