History of Switzerland
Switzerland's most important exports during the war were precision machine tools, watches, jewel bearings (used in bombsights), electricity, and dairy products. During World War Two, the Swiss franc was the only remaining major freely convertible currency in the world, and both the Allies and the Germans sold large amounts of gold to the Swiss National Bank. Between 1940 and 1945, the German Reichsbank sold 1.3 billion francs worth of gold to Swiss Banks in exchange for Swiss francs and other foreign currency.
European integration
The European Economic Area (EEA) agreement allows Norway, Iceland and Liechtenstein to participate in the European Single Market without joining the EU. The four basic freedoms apply. However, some restrictions on fisheries and agriculture take place. Switzerland is linked to the European Union by Swiss-EU bilateral agreements, with a different content from that of the EEA agreement.
The Eurozone refers to the European Union member states that have adopted the euro currency union as the third stage of the European Economic and Monetary Union (EMU). Further, certain states outside the EU have adopted the euro as their currency, despite not belonging to the EMU. Thus, a total of 25 states, including 19 European Union states and six non-EU members, currently use the euro.
