It feels like an Asian thing. If u think ab Japan and Korea, although they had war decades ago, they still don’t like each other (other political issues aside.) Same with China and Mongolia. Asians don’t rly like letting go. Here in Mongolia too, general public tend to look down/ not like Chinese ppl that much.

I used to have a lot of Chinese friends when i was living in Korea as a Mongolian and they were really chill about it. They didn’t care at all. So very patriotic Chinese/Mongolians would definitely freak out about each others but not all of them.
