He defined the concept of WTO and its role as well as its positive and negative impacts on the economic sectors like agriculture, insurance, petrochemical industries, governmental projects and tourism. Dr Al-Qahtani called for adopting policies that protect the Saudi economy from the unfair competition notably after the world economic crisis.
