The exchange of goods among people, states and countries is referred to as a trade. The market is the place where such exchanges take place. Trade between two countries is called international trade. It may take place through sea, air or land routes. While local trade is carried out in cities, towns and villages, state-level trade is carried out between two or more states. The advancement of international trade of a country is an index to its economic prosperity. It is, therefore, considered the economic barometer for a country. As the resources are space-bound, no country can survive without international trade. Export and import are the components of the trade.
