Dr Al-Assaf also spoke about the Kingdom's role regionally and internationally, and its efforts to join the World Trade Organization (WTO). He cited a strong global demand for oil, plus factors such as tense situations in certain parts of the world, as having an impact on oil prices, and stressed the need for cooperation among oil producing and oil consuming countries in order to preserve oil price stability under the auspices of the Riyadh-based International Energy Forum.
