The sharp increase in the international prices of crude oil has been attributed to the political tension in the Middle East, concerns about the sustainability of international crude oil production and high demand for crude oil by China.

In addition, the increase in oil prices has also been attributed to uncertainty about the future of the Russian oil producer Yukos, efforts by crude oil producing countries to increase earnings from crude oil sales and international market speculation, the Department of Minerals and Energy said.
