International trade is the exchange of goods and services produced in one country for goods and services produced in another country. In addition to visible trade, which involves the import and export of goods and merchandise, there is also invisible trade, which involves the exchange of services between nations. Nations such as Greece and Norway have large maritime fleets and provide transportation service. This is a kind of invisible trade. Invisible trade can be as important to some nations as the export of raw materials or commodities is to others. In both cases, the nations earn the money to buy necessities.
(B)
There is no country in the world that can produce all the products it needs. Thus countries join in international division of labor for effective production and reproduction. Sometimes a country can buy goods and services from abroad on a barter （易货）basis. Barter means doing business by exchanging goods of one sort for goods of another sort without using money. Barter trade itself is not enough to meet a country’s import needs. But as a form of international trade, it is still attractive in developing countries where foreign exchange is in short supply and inflow of foreign funds is far from sufficient to meet their obligations in external trade.
(C)
There is only a small proportion of service activity in international trade. By their very nature, services are much less tradable than goods since services have to be consumed at the point where they are produced. This means that either the supplier of a service must move to where the consumer is located, or the consumer must move to where the producer is located. Only a small proportion of services are capable of being traded like goods with neither the producer nor the consumer being required to move. For example, transport services, banking, insurance and education.
