Regulation of international trade

Traditionally trade was regulated through bilateral treaties between two nations. For centuries under the belief in Mercantilism most nations had high tariffs and many restrictions on international trade. In the 19th century, especially in Britain, a belief in free trade became paramount and this view has dominated thinking among western nations for most of the time since then. In the years since the Second World War multilateral treaties like the GATT and World Trade Organization have attempted to create a globally regulated trade structure.

Free trade is usually most strongly supported by the most economically powerful nations in the world, though they often engage in selective protectionism for those industries which are politically important domestically, such as the protective tariffs applied to agriculture and textiles by the United States and Europe.

The Netherlands and the United Kingdom were both strong advocates of free trade when they were economically dominant, today the United States, the United Kingdom, Australia and Japan are its greatest proponents.

However, many other countries (such as India, China and Russia) are increasingly becoming advocates of free trade as they become more economically powerful themselves. As tariff levels fall there is also an increasing willingness to negotiate non tariff measures, including foreign direct investment, procurement and trade facilitation. The latter looks at the transaction cost associated with meeting trade and customs procedures.

Traditionally agricultural interests are usually in favour of free trade while manufacturing sectors often support protectionism. This has changed somewhat in recent years, however. In fact, agricultural lobbies, particularly in the United States, Europe and Japan, are chiefly responsible for particular rules in the major international trade treaties which allow for more protectionist measures in agriculture than for most other goods and services.

During recessions there is often strong domestic pressure to increase tariffs to protect domestic industries. This occurred around the world during the Great Depression leading to a collapse in world trade that many believe seriously deepened the depression.

The regulation of international trade is done through the World Trade Organization at the global level, and through several other regional arrangements such as MERCOSUR in South America, NAFTA between the United States, Canada and Mexico, and the European Union between 25 independent states. The 2005 Buenos Aires talks on the planned establishment of the Free Trade Area of the Americas (FTAA) failed largely due to opposition from the populations of Latin American nations. Similar agreements such as the MAI (Multilateral Agreement on Investment) have also failed in recent years.
