Most genocides in history didn't rely on any data (Caesar or Genghis Khan certainly didn't run any population analysis before putting entire cities to the sword) and most databases have never been used for a genocide. The correlation is weak.
What actually prevents genocides is good institutions, not deliberate ignorance.

And you would trust China in that, a country that locks up Muslims in concentration camps and surveillances its citizens to a degree the Soviet KGB and German Stasi wouldn't have dreamt of?
I agree with your first sentence. China cannot be trusted. I grew up in late Communist Czechoslovakia, I have no illusions about totalitarian states.
All the more reason why not leave the entire field of human genetics exclusively to them - imagine a future in which rich and influential people can get treatments for certain deadly diseases only in Shanghai and Beijing and China demands not only money, but allegiance for keeping them alive.
As for your last sentence: this ship has sailed some twenty years ago. At the current stage, China can only seriously damage/destroy itself from within. Totalitarian states are weaker than they appear, though. It may very well happen.
