Abstract
Now, in 2007, international exchanges in the world has become very frequent. Since 1945, we have seen a very strong growth of international exchanges, the world exports has progressed twice as quickly as world production. World trade accounted for 10% of the world wealth in 1960 whereas it represents more than 25% now. It is a consequence of the liberalist system. In fact, international trade is the exchange of goods and services in the entire world. We will speak about this phenomenon and explain it. We will work around one main question, that is, 'is the opening of international exchanges always a synonym of growth?'
