But you have to keep in mind that not everyone will be willing to receive "savages" on their ports and land so that they can move to Switzerland. Even if the government did, there's no saying the local population would like it.
Europeans did not view the Chinese comparably to indigenous peoples in the Americas, or Africans. You are making broad assumptions without any evidence. Besides, it's not like European nations had extremely effective port control affording easy management of travel. Borders were far more porous then than they are now. And guests of a sovereign nation would not likely be turned away.
