Even in the absence of the constraints imposed by the most favoured nation and national treatment clauses, it is sometimes easier to obtain general multilateral agreements than separate bilateral agreements. In many cases, the potential loss resulting from a concession to a country is almost as great as that which would result from a similar concession to many countries. The benefits to the most efficient producers from global tariff reductions are significant enough to warrant substantial concessions. Since the implementation of the General Agreement on Tariffs and Trade (GATT, 1948) and its successor, the World Trade Organization (WTO, 1995), global tariffs have declined considerably and world trade has increased. The WTO contains provisions on reciprocity, the status of the most favoured nation and the domestic treatment of non-tariff restrictions. She has been involved in the architecture of the most comprehensive and important multilateral trade agreements of modern times. The North American Free Trade Agreement (1993) and the European Free Trade Association (1995) are examples of these trade agreements and their representative institutions. The United States is a member of the World Trade Organization (WTO) and the Marrakesh Agreement establishing the World Trade Organization (WTO) contains rules for trade among the 154 members of the WTO. The United States and other WTO members are currently participating in the WTO negotiations on development in Doha and a strong and open Doha agreement on both goods and services would go a long way in managing the global economic crisis and restoring the role of trade in promoting economic growth and development.
The following video explains and compares the different types of trade agreements: trade agreements open many doors for businesses. With access to new markets, competition intensifies. Increasing competition is forcing companies to produce better quality products. It also leads to greater diversity for consumers. If there are a variety of high quality products, companies can improve customer satisfaction. On the other hand, some local industries benefit. They are finding new markets for their duty-free products. These industries are growing and employing more labour. These compromises are the subject of endless debate among economists. Customs unions are agreements between countries in which the parties agree to allow the free trade of products within the customs union and they agree on a common external tariff (CET) for imports from the rest of the world. It is this CET that distinguishes a customs union from a regional trade agreement.
It is important to note that, although trade within the Union is comprehensive, customs unions do not allow the free movement of capital and labour between Member States. The customs union of Russia, Belarus and Kazakhstan, founded in 2010, is an example. These countries have removed trade barriers between them, but they have also agreed on some common policies on relations with third countries. Depending on the conditions and concessions agreed by the participating bodies, there are different types of trade agreements – Companies in Member States benefit from increased incentives to trade in new markets through attractive trading conditions due to the measures contained in the agreements. Regional trade agreements refer to a treaty signed by two or more countries to promote the free movement of goods and services beyond the borders of its members. The agreement contains internal rules that Member States comply with each other. As far as third countries are concerned, there are external rules to which members comply. However, the WTO has expressed some concerns. According to Pascal Lamy, Director-General of the WTO, the dissemination of regional trade agreements (RTA) is “… is the concern of inconsistency, confusion, exponentially increasing costs for businesses, unpredictability and even injustice in trade relations.  The WTO is the way in which typical trade agreements (call for
