Kuwait Petroleum Corporation (KPC) CEO Faruk Al-Zanki said Monday that the unrest in the Mideast and North African region has lifted oil prices by around 20 percent. Zanki said on the sidelines of an oil and gas summit that started Monday the oil prices would hike further if the turmoil covers all over the Mideast that houses several of the world's main oil exporters. The earthquake in Japan also helped to lift the prices, said Zanki, who opened the two day summit with Venezuelan former Energy Minister Alirio Parra. The annual summit would tackle diversification, development and growth in the oil industry. Kuwait, the fourth largest exporter of the Organization of Petroleum Exporting Countries (OPEC), sits atop around 10 percent of the world's proven oil reserves and pumps around 2.3 million barrels under OPEC's quota.
