The European Free Trade Association (EFTA) is a regional trade organization and free trade area consisting of four European states: Iceland, Liechtenstein, Norway and Switzerland. The organization operates in parallel with the European Union (EU), and all four member states participate in the European Single Market and are part of the Schengen Area. They are not, however, party to the European Union Customs Union.

Liechtenstein, officially the Principality of Liechtenstein, is a doubly landlocked German-speaking microstate located in the Alps between Austria and Switzerland. Liechtenstein is a semi-constitutional monarchy headed by the prince of Liechtenstein of the House of Liechtenstein, currently led by Hans-Adam II. Liechtenstein is bordered by Switzerland to the west and south and Austria to the east and north. It is Europe's fourth-smallest country, with an area of just over 160 square kilometres and a population of 39,790. It is the world's smallest country to border two countries.
