LIECHTENSTEIN is one of only two countries in the world (along with Uzbekistan) that is “doubly landlocked.” That means people there must cross the borders of at least two other nations before reaching the sea. Liechtenstein also has no airport. For many countries, being landlocked has often meant economic struggle, yet Liechtenstein is one of the world’s wealthiest nations—thanks largely to a low business tax rate that attracts investment, robust manufacturing and financial sectors, and a long history of political stability.
