European Economic Area in the context of "Open border"

The European single market, also known as the European internal market or the European common market, is the single market comprising mainly the 27 member states of the European Union (EU). With certain exceptions, it also comprises Iceland, Liechtenstein, Norway (through the Agreement on the European Economic Area), and Switzerland (through sectoral treaties). The single market seeks to guarantee the free movement of goods, capital, services, and people, known collectively as the four freedoms of the European Union. This is achieved through common rules and standards that all participating states are legally committed to follow.

Any potential EU accession candidates are required to make association agreements with the EU during the negotiation, which must be implemented prior to accession. In addition, through three individual agreements on a Deep and Comprehensive Free Trade Area (DCFTA) with the EU, Georgia, Moldova, and Ukraine have also been granted limited access to the single market in selected sectors. Turkey has access to the free movement of some goods via its membership in the European Union–Turkey Customs Union. The United Kingdom left the European single market on 31 December 2020. An agreement was reached between the UK Government and European Commission to align Northern Ireland on rules for goods with the European single market, to maintain an open border on the island of Ireland.

A free trade area is the region encompassing a trade bloc whose member countries have signed a free trade agreement (FTA). Such agreements involve cooperation between at least two countries to reduce trade barriers, import quotas and tariffs, and to increase trade of goods and services with each other. If natural persons are also free to move between the countries, in addition to a free trade agreement, it would also be considered an open border. It can be considered the second stage of economic integration.

Customs unions are a special type of free trade area. All such areas have internal arrangements which parties conclude in order to liberalize and facilitate trade among themselves. The crucial difference between customs unions and free trade areas is their approach to third parties. While a customs union requires all parties to establish and maintain identical external tariffs with regard to trade with non-parties, parties to a free trade area are not subject to this requirement. Instead, they may establish and maintain whatever tariff regime applying to imports from non-parties as deemed necessary. In a free trade area without harmonized external tariffs, to eliminate the risk of trade deflection, parties will adopt a system of preferential rules of origin.

Liechtenstein (/ˈlɪktənstaɪn/ , LIK-tən-styne; pronounced [ˈlɪçtn̩ʃtaɪn] ; Alemannic German: Liachtaschta), officially the Principality of Liechtenstein (German: Fürstentum Liechtenstein [ˈfʏʁstn̩tuːm ˈlɪçtn̩ʃtaɪn] ), is a doubly landlocked country in the Central European Alps. It is located between Austria to the east and north-east and Switzerland to the north-west, west and south. Formed in 1719, Liechtenstein became fully independent upon the dissolution of the German Confederation in 1866. Liechtenstein is a monarchy headed by the prince of Liechtenstein. Hans-Adam II, Prince of Liechtenstein has reigned over Liechtenstein since 1989. Liechtenstein is Europe's fourth-smallest country, with an area of just over 160 square kilometres (62 square miles) and a population of 41,389. It is the world's smallest country to border two countries, and is one of the few countries with no debt. Its official language is German.

Liechtenstein is divided into 11 municipalities. Its capital is Vaduz, and its largest municipality is Schaan. It is a member of the United Nations, the European Free Trade Association, and the Council of Europe. It is not a member state of the European Union, but it participates in both the Schengen Area and the European Economic Area. It has a customs union and a monetary union with Switzerland, with its usage of the Swiss franc. A constitutional referendum in 2003 granted the monarch greater powers, including the power to dismiss the government, nominate judges and veto legislation.

The Deep and Comprehensive Free Trade Areas (DCFTA) are three free trade areas established between the European Union, and Georgia, Moldova, and Ukraine respectively. The DCFTAs are part of each country's EU Association Agreement. They allow Georgia, Moldova, and Ukraine access to the European Single Market in selected sectors and grant EU investors in those sectors the same regulatory environment in the associated country as in the EU. The agreements with Moldova and Georgia have been ratified and officially entered into force in July 2016, although parts of them were already provisionally applied. The agreement with Ukraine was provisionally applied since 1 January 2016 and formally entered into force on 1 September 2017.

Unlike standard free trade areas, the DCFTA is aimed to offer the associated country the "four freedoms" of the EU Single Market: free movement of goods, services, capital, and people. Movement of people however, is in form of visa-free regime for short stay travel, while movement of workers remains within the remit of the EU Member States. The DCFTA is an "example of the integration of a Non-EEA-Member into the EU Single Market".

The European Economic Community (EEC) was a regional organisation created by the Treaty of Rome of 1957, aiming to foster economic integration among its member states. It was subsequently renamed the European Community (EC) upon becoming integrated into the first pillar of the newly formed European Union (EU) in 1993. In the popular language, the singular European Community was sometimes inaccurately used in the wider sense of the plural European Communities, in spite of the latter designation covering all the three constituent entities of the first pillar. The EEC was also known as the European Common Market (ECM) in the English-speaking countries, and sometimes referred to as the European Community even before it was officially renamed as such in 1993. In 2009, the EC formally ceased to exist and its institutions were directly absorbed by the EU. This made the Union the formal successor institution of the Community.

The Community's initial aim was to bring about economic integration, including a common market and customs union, among its six founding members: Belgium, France, Italy, Luxembourg, the Netherlands and West Germany. It gained a common set of institutions along with the European Coal and Steel Community (ECSC) and the European Atomic Energy Community (EURATOM) as one of the European Communities under the 1965 Merger Treaty (Treaty of Brussels). In 1993, a complete single market was achieved, known as the internal market, which allowed for the free movement of goods, capital, services, and people within the EEC. In 1994 the internal market was formalised by the EEA agreement. This agreement also extended the internal market to include most of the member states of the European Free Trade Association, forming the European Economic Area, which encompasses 15 countries.
