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.
Ah, thanks; I actually don’t know about the events, I was repeating what the guy who replied said.
