I'm tellin' ya' man, after thousands of years, it still the same. Japan and China hate each other.
Japan doesn't like the Koreans who don't like the Chinese or Japanese. And the Chinese think they're superior to all Asian countries. It looks like a small thing but it's big to them. All those countries are just waiting for a chance to poke each other in the eye over something, anything.
The Chinese more than likely just accidentally contaminated the dumplings but of course the Japanese think it's a conspiracy. I'm tellin' ya it
never ends.
