Trade is commonly defined as the voluntary exchange of goods or services; in the modern world these are usually exchanged for money. ‘Trade’ involves both buying and selling activities but the focus is on the needs of producers and distributors (usually companies). ‘Marketing’ involves finding buyers for a given quality and quantity of product on the most advantageous terms for the seller and therefore focuses on understanding the needs of the buyer. International buyers are commonly traders or retailers that reflect or presume the requirements of the consumers they serve. In the case of international trade, producers and buyers are usually located in different countries although the advent of integrated multinational agribusinesses and supermarkets complicates this situation.
