Export and import are two basic elements in international trade. Export refers to the sale of goods and services produced in a country to other countries, while import means buying goods and services from other countries and importing them into the country. Export and import bring many benefits to countries. First, exporting allows a country to exploit its comparative advantage. Each country, based on its natural resources, technical expertise and labor force, has the ability to produce goods and services that can be the best supplier in the world market. On the other hand, imports allow the country to meet domestic needs that are not readily available.
