As the title says. POD is 1868 when Japan begins the Meiji Ishin. AHC a non-Japanese power takes Formosa from China.
In the 19th century? Absolutely not. They might be able to keep it with a POD in the17th century, but in the 19th century the Netherlands was a mere shell of what it used to be.It was now a poor backwards country that would not be able to project its power so far from its core (which in this case be the Dutch East Indies.Uh, the Dutch? Who sorta had it as I recall?
In saying that, I see Taiwan as being a bit like Asia's Congo. None of the great powers will want any of the other great powers to have it, resulting in a sort of political stalemate. Only in this case it doesn't go to neutral Belgium - it remains with China.
Or you could have the Great Powers award it to one of the lesser countries for that reason, like the Dutch and their claim on it.
Could France take it after the Sino-French War?
