Some countries did this, but not most. At that time, the international community did not clamor for a travel ban on India, which is completely different from the current calls around the world to ban Chinese tourists from traveling. And don't forget that now covid is over, that's the collective consensus around the world.
The current calls seem to be more based on emotional and irrational thinking.
And this history also tells us that the travel ban is useless, I thought this was the consensus of most of this forum, but it seems that this only applies to non-China regions, what kind of logic is this
