This research aims to study the Gat arrangement and how it reflects on and affects the economies of the undeveloped countries as in the case of Syria. There might be advantages and disadvantages of Global Trade Organization on the Syrian economy in spite of the fact that this treaty has been signed in a time of increase in industrial production in the developed countries which aim to sell their products and increase their profits. Perhaps, Syria's joining Gat might benefit and help develop its industries, decrease the cost of production and improve the economy.
