Foreign Trade International trade is the exchange of goods and services across international boundaries or territories. In most countries, it represents a significant share of GDP. While international trade has been present throughout much of history (see Silk Road, Amber Road), its economic, social, and political importance has been on the rise in recent centuries. Industrialization, advanced transportation, globalization, multinational corporations, and outsourcing are all having a major impact. Increasing international trade is the primary meaning of "globalization".

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.
