From time to time, you will hear about fast track trade laws, in which Congress would give the president the power to negotiate trade agreements. This law has not been passed and remains controversial. A trade agreement (also known as a trade pact) is a large-scale tax, customs and trade agreement, which often includes investment guarantees. It exists when two or more countries agree on conditions that help them trade with each other. The most frequent trade agreements are preferential and free trade regimes to reduce (or remove) tariffs, quotas and other trade restrictions imposed on intermediaries. U.S. tariffs are at their lowest in history. Before the Second World War, they were up to 40% for some imports. Today, customs revenues account for less than 5% of the volume of imports and the dollar, and many imports are exempt from tariffs and quotas.
Non-tariff barriers have also been largely eliminated, but not completely. A government does not need to take concrete steps to promote free trade. This upside-down attitude is called “laissez-faire trade” or trade liberalization. That does not mean that everything is rosy in the world of foreign trade, nor does it mean that the United States is still playing fairly in the global marketplace. U.S. agricultural subsidies and textile tariffs, for example, impede imports of food, wipes and clothing from poor countries to protect these domestic industries. Nevertheless, the United States and the world at large should continue on the path of freer international trade. The creation of free trade zones is seen as an exception to the most privileged principle of the World Trade Organization (WTO), since the preferences of the parties to the exclusive granting of a free trade area go beyond their accession obligations.  Although GATT Article XXIV authorizes WTO members to establish free trade zones or to conclude interim agreements necessary for their establishment, there are several conditions relating to free trade zones or interim agreements leading to the creation of free trade zones.
Regional trade agreements are very difficult to conclude and claim when countries are more diverse. A definite prognosis is that international trade agreements will continue to be controversial. The guides are aimed in particular at small and medium-sized exporters and tell you what each agreement produces without having to read the detailed technical language of the full text. The world`s major countries introduced the GATT in response to the waves of protectionism that paralyzed and contributed to world trade during the Great Depression of the 1930s. Successive GATT “cycles” have significantly reduced customs barriers on industrial products in industrialized countries. Since the beginning of the GATT in 1947, the average tariffs set by industrialized countries have increased from about 40% to about 5% today. These tariff reductions helped to promote both the considerable expansion of world trade after the Second World War and the resulting increase in real per capita income between developed and developing countries. The annual benefit of the elimination of tariff and non-tariff barriers resulting from the Uruguay Round agreement (negotiated between 1986 and 1993 under the aegis of GATT) was estimated at about $96 billion, or 0.4% of global GDP. The logic of formal trade agreements is that they reduce penalties for deviation from the rules set out in the agreement.
 As a result, trade agreements make misunderstandings less likely and create confidence on both sides in the sanction of fraud; this increases the likelihood of long-term cooperation.  An international organization such as the IMF can further encourage cooperation by monitoring compliance with agreements and reporting violations.  It may be necessary to monitor international agencies to detect non-tariff barriers that are disguised attempts to create barriers to trade.
