Tickrrguy is right that developing viruses that kill your enemy and not you is simply not a realistic goal.

That won't stop the Chinese from trying. Their ideology is this:

China is the center of the universe.

The Han are a race of supermen fated to rule the world, and the only truly civilized breed of humanity.

Their Emperor is God incarnate.

Non-Chinese are nothing but animals to be used as beasts of burden or vermin to be exterminated. They do not consider us human at all.

Anybody who thinks, wrongly, that white people are racists has never had much to do with Chinese, whose bigotry would have been breath-taking even by Nazi German standards.

(Oh, yes, by the way---they really, REALLY hate Jews. Anti-Semitic conspiracy theories of western politics are very popular in China. No prizes for guessing why deep-cover PLA officers "studying" in America are prone to seducing upwardly-mobile Jewish boys.)
