The economic structure of Middle Eastern nations are different in the sense that while some nations are heavily dependent on export of only oil and oil-related products (such as Saudi Arabia, the UAE and Kuwait), others have a highly diverse economic base (such as Cyprus, Israel, Turkey and Egypt). Industries of the Middle Eastern region include oil and oil-related products, agriculture, cotton, cattle, dairy, textiles, leather products, surgical instruments, defence equipment (guns, ammunition, tanks, submarines, fighter jets, UAVs, and missiles). Banking is also an important sector of the economies, especially in the case of UAE and Bahrain.
