Trading blocs
A regional trading bloc is a group of countries within a geographical region that protect themselves from imports from non-members. Trading blocs are a form of economic integration, and increasingly shape the pattern of world trade. There are several types of trading bloc:
Preferential Trade Area
Preferential Trade Areas (PTAs) exist when countries within a geographical region agree to reduce or eliminate tariff barriers on selected goods imported from other members of the area. This is often the first small step towards the creation of a trading bloc.
Free Trade Area
Free Trade Areas (FTAs) are created when two or more countries in a region agree to reduce or eliminate barriers to trade on all goods coming from other members.
Customs Union
A customs union involves the removal of tariff barriers between members, plus the acceptance of a common (unified) external tariff against non-members. This means that members may negotiate as a single bloc with 3rd parties, such as with other trading blocs, or with the WTO.
Common Market
A ‘common market’ (or single market) is the first significant step towards full economic integration, and occurs when member countries trade freely in all economic resources – not just tangible goods. This means that all barriers to trade in goods, services, capital, and labour are removed. In addition, as well as removing tariffs, non-tariff barriers are also reduced and eliminated. For a common market to be successful there must also be a significant level of harmonisation of micro-economic policies, and common rules regarding monopoly power and other anti-competitive practices. There may also be common policies affecting key industries, such as the Common Agricultural Policy (CAP) and Common Fisheries Policy (CFP) of the European Single Market (ESM).
