Why are switzerland's initials "SUI"?

Travel Tips

the "offical" name of Switzerland is Confoederatio Helvetica (CH) but this is normally not used internationally. derived from the french word for Switzerland (Suisse), SUI has been taken as the offical abbreviation (due to the offical language french used at the olympic games).
Switzerland has four offical languages, German, French, Italian and Romansh.

Probably has a lot to do with the fact that "Suisse" is the proper spelling of Swiss in Switzerland.

Well Suitzerland, cause at the middle age speaks German an Flamish that's why they take the "SUI"
