Abstract
Nowadays, it is paradoxical to see the development, in a global world, of several types of regions. This process began after the Second World War, with the development of the international trade flows between economies. The creation in 1957 of the European Economic Community, by the Treaty of Rome, has launched this phenomenon. In response to this trend, other countries in the world, seeing the creation of this bloc, have created free trade areas, customs unions or common markets. Thus, we have seen the creation of the American Common market in 1960, the African Common Market in 1962 and other forms of regional protectionist unions. This phenomenon can be assimilated as the ‘Old Regionalism', which had a tendency to create regional integration agreements and further the form of defensive protectionism.
