The well sourced Wikipedia article indicates there is some conflict among the international community. Some people are calling China's treatment of the Uyghurs a genocide even without well documented mass murder. Other's are just calling "cultural genocide" and a "crime against humanity".
Whichever technical point you want to pick is up to you. Either way the treatment of the Uyghur people is unethical and the Chinese government is undoubtedly trying to erase the Uyghur people and their culture from existence.
