After what China did to Japan 500 years ago (under Mongol rule) (not Mongol rule as a hexbearer pointed out actually), they have no right to condemn Japan for anything; also bacteria, viruses, what's the difference? Also it was an attack, not an epidemic that formed naturally like they have throughout history.
We went through and entire pandemic and fascist dipshits like this still don't know the difference between bacteria and viruses. It'll blow their mind when they learn about bacteriophages.
And they'll go blithering mad when they learn about viroids
