Almost every kind of product can be found on the international market：food, clothes, spare parts, oil, jewelry, wine, stocks, currencies and water. Services are also traded： tourism, banking, consulting and transportation. A product that is sold to the global market is an export, and a product that is bought from the global market is an import.

International trade can benefit us a lot. Trading globally allows us to expand our markets for both goods and services that otherwise may not have been available to us.
