Import Export International trade is one of the hot industries of the new millennium. But it's not new. Think Marco Polo. Think the great caravans of the biblical age with their cargoes of silks and spices. Think even further back to prehistoric man trading shells and salt with distant tribes. Trade exists because one group or country has a supply of some commodity or merchandise that is in demand by another. And as the world becomes more and more technologically advanced, as we shift in subtle and not so subtle ways toward one-world modes of thought, international trade becomes more and more rewarding, both in terms of profit and personal satisfaction.
