Switzerland has high degrees of economic freedom, immigrants, and globally-oriented business. Switzerland is one of the richest countries in the world. It is bordered by Germany, France, Italy, Austria and Liechtenstein and has a long history of neutrality — it has not been at war since 1815 — and hosts many international organizations, including the Red Cross, the World Trade Organization and one of the U.N.'s two European offices. Switzerland is multilingual and has four national languages: German, French, Italian and Romansh. The country's Latin formal name, Confoederatio Helvetica is derived from the Helvetii, an ancient Celtic people in the Alpine region.
