I have noticed that in some countries many city elements such as streets (where they have names, not numbers), squares, parks etc. might bear important foreign figure names, capital city names (e.g. Tokyo, Paris).
One example that comes into my mind is Charles de Gaulle, who has many avenues and squares named after him across the entire world.
I wonder how does one country obtain things outside its territory named after import political or cultural figures.
Question: How can a country get a street / square / park in another country named after an important figure?
