You assume that a regime that does exterminate an ethnicity makes it appear from the outset as their ultimate goal. Historians of the Holocaust rigorously debate whether the Nazis intended from the start to exterminate all Jews worldwide. There's no straightforward answer. If you want to know where the threat of genocide exists, you don't look merely at rhetoric. Genocide happens across several discrete stages. It usually starts with popular sentiments such as "you are not like us, you are not one of us", proceeds to "you may not live among us", then ultimately ends in "you may not live". China is at the step immediately before extermination. The number one predictor of extermination isn't rhetoric, it's ghettoization and internment.
