Genocide is killing people for their ethnicity in an effort to wipe all of them out. What Russia and China are doing (to Ukrainians and Uyghurs) is more like colonization with a heavy handed attempt at destroying any independent national identity (especially native language) over one generation, by force yes, but trying to avoid an outright Holocaust because they want these people as loyal workers. What their victims need is more understanding and indeed more advocates and protests from the Russian and Han Chinese populations.
