Trade can be defined as the sale of goods from one country to another. It is known as import (seen from the country into which the goods are shipped) or export (seen from the country from which the goods are shipped).

Investment can be defined as the incorporation of a company in the foreign country, or as a financial investment in a company incorporated in the foreign country (generally in the form of an equity Joint Venture).
