Esperanto was intended as a sort of diplomatic language. It's got flaws, definitely. The sounds and spelling are very much from the creator's native Polish, a lot of important terms are rather obscure («Usono,» from "Usonia" is the word for the United States). That said, it is in the end relatively easy to learn, and it is easy to express the ideas of diplomacy, science, and civil society.
China and Japan used to have a lot of Esperantists before WWII, for that reason.

> After World War I, the League of Nations considered adopting Esperanto as a working language and recommending that it be taught in schools, but proposals along these lines were vetoed by France.
It may be Eurocentric, but it's hell of a lot easier for diplomats to learn than English or French!
