accounts for more than one-third of the world total. The European Union or EU is a supranational union of European states, the most recent acceding member being Croatia, which became full member on 1 July 2013. It has many functions, the most important being the establishment and maintenance of a common single market, consisting of a customs union, a single currency (adopted by 18 of the member states), a Common Agricultural Policy and a Common Fisheries Policy. The European Union also undertakes various initiatives to co-ordinate activities of the member states. The union has evolved over time from a primarily economic union to an increasingly political one. This trend is highlighted by the increasing number of policy areas that fall within EU competence: political power has tended to shift upwards from the Member States to the EU. European Free Trade Association The European Free Trade Association (EFTA) was established on 3 May 1960 as an alternative for European states that did not wish to join the European Union, creating a trade bloc with fewer central powers. The EFTA member states as of 1992 were Austria, Denmark, Finland, Iceland, Liechtenstein, Norway, Sweden and Switzerland. In 2014 only four countries, Iceland, Norway, Switzerland and Liechtenstein, remained members of EFTA, as the other members have gradually left to join the EU. European Economic Area The European Economic Area (EEA) came into being on 1 January 1994 following an agreement between the European Free Trade Association (EFTA) and the European Union (EU). It was designed to enable EFTA countries to participate in the European Single Market without having to join the EU. In a referendum, Switzerland (ever keen on neutrality) chose not to participate in the EEA (although it is linked to the European Union by bilateral agreements similar in content to the EEA agreement), so the current members are the EU states plus Norway, Iceland and Liechtenstein. A Joint Committee consisting of the non EU members plus the European Commission (representing the EU) has the function of extending relevant EU Law to the non EU members. Commonwealth of Independent States The Commonwealth of Independent States (CIS) is a confederation consisting of 9 of the 15 states of the former Soviet Union, (the exceptions being the three Baltic states, Georgia, Turkmenistan, and Ukraine (Turkmenistan and Ukraine are participating states in the CIS)). Although the CIS has few supranational powers, it is more than a
