The document discusses the potential for aluminium production to diversify the economies of Middle Eastern countries away from their dependence on oil. It notes that several Gulf countries have established large aluminium smelting industries over the past few decades, with the six primary smelters in the region producing over 4.9 million tons in 2014. As oil prices decline and reserves are depleted, expanding industries like aluminium will become increasingly important to Middle Eastern economies. The document argues that the region has competitive advantages for aluminium production, like low-cost energy resources and labor, but that foreign investment could be limited by strict rules regarding local hiring and conservative social environments.
