In my opinion, it meets the definition of genocide specifically on preventing births, and partially and to an extent on some of the other ones such as mental harm and parent-child separation. The intention is to break and assimilate the Uighurs. In this sense, I do not believe that this is a genocide like the Nazi genocide of literally trying to obliterate the ethnic group in whole, but it's designed to destroy the ethnic group in part in terms of identity and even population size.
