Look up the definition of genocide you would be surprised that mass culling are just one aspect of it.
Also oppressing people on the basis of economic progress are very capitalistic thinking don't u know. What would uncle Mao say to that I wonder?
ZENZ: I have long argued that the atrocity in the region is a cultural genocide, not a literal genocide. I do continue to believe that, generally speaking, the Chinese government does not intend to physically eradicate the Uighurs and Kazakhs, just to integrate, subjugate, dominate and assimilate them. However, this is coupled with a policy of ethnoracial domination, as the government has brought millions of Han Chinese settler in the regions with promises of high salaries, jobs and free housing.
The reason why now this has changed - we do need to probably call it a genocide - is quite simply because the evidence now, for the first time, very specifically meets one of the five criteria set forth by the United Nations Convention for the Punishment and Prevention of the Crime of Genocide from 1948, which specifically says the suppression of birth.
BTW this is from your government source:

If the uighur are the majority & did half the things you people did to them you will not be saying this to be a good thing.
