I found this gem in a June 21, 1900 Washington Post article:
It is a cute, and surely manufactured story, but it does get at something I have wondered about: did Asian powers who were granting special rights in their ports to Europeans ever seek any similar special trade access to certain ports in Europe?
That is funny. Less so, perhaps, when you realize how close Japan was at that point to having the right to give away access to Korean ports….
I’m not aware of any reciprocal trade rights in the unequal treaties: certainly it never comes up when they’re dealing with immigration restrictions later.
