There are currently a number of free trade agreements in the United States. These include multi-nation agreements such as the North American Free Trade Agreement (NAFTA), which includes the United States, Canada and Mexico, and the Central American Free Trade Agreement (CAFTA), which includes most Central American nations. There are also separate trade agreements with nations, from Australia to Peru. The European Union is now a remarkable example of free trade. Member States form an essentially borderless unit for trade purposes, and the introduction of the euro by most of these countries paves the way. It should be noted that this system is governed by a Brussels-based bureaucracy, which has to deal with the many trade-related issues that arise between the representatives of the Member States. Governments with free trade policies or agreements do not necessarily abandon import and export controls or eliminate all protectionist policies. In modern international trade, few free trade agreements lead to completely free trade. Both the creation of trade and the diversion of trade have a decisive impact on the establishment of a free trade agreement. The creation of trade will result in a shift in consumption from a cost producer to a low-cost producer, which will lead to an expansion of trade. On the other hand, trade diversion will mean that trade will move from a low-cost producer outside the zone to a more expensive producer in the free trade agreement.  Such offshoring will not benefit consumers under the free trade agreement, which will be deprived of the opportunity to purchase cheaper imported goods. However, economists note that trade diversion does not always harm the overall national well-being: it can even improve national well-being as a whole if the volume of misappropriated trade is low.
 It should also be stressed that a free trade agreement is a reciprocal agreement that is authorized by Article XXIV of the GATT. Autonomous trade agreements for developing and least developed countries are permitted by the 1979 decision by the signatories of the General Agreement on Tariffs and Trade (GATT) («empowerment clause») on differentiated and more favourable treatment, reciprocity and increased participation of developing countries. It forms the legal basis for the WTO`s Generalized Preference System (GSP).  Free trade agreements and preferential trade agreements (as mentioned by the WTO) are considered an exception to the MFN principle.  A free trade agreement is an agreement between two or more countries to facilitate trade and remove trade barriers. The aim is to eliminate tariffs completely from day one or over a number of years. In general, trade diversion means that a free trade agreement would divert trade from more efficient suppliers outside the zone to less efficient suppliers within the territories. Whereas the creation of trade implies the creation of a free trade area that might not otherwise have existed. In any case, the creation of trade will increase a country`s national well-being.  A free trade agreement helps create a level playing field for U.S. workers and businesses to succeed. These agreements create a more responsible and equitable trade relationship between two or more countries.
