Liechtenstein's foreign economic policy has been dominated by its customs union with Switzerland (and with Austria-Hungary until World War I).
Unlike Switzerland however (where citizens rejected membership in a referendum), Liechtenstein is part of the European Economic Area.
Liechtenstein maintains resident embassies in Austria, Belgium, Germany, the Holy See, Switzerland and the United States, along with a number of missions to international organisations.
An offer from the Czech Republic to return the palaces and castles (without the surrounding land) was rejected by Liechtenstein.
[7] Liechtenstein's ruling prince, Hans-Adam II, has announced that the principality will take no further legal action to recover the appropriated assets.
