The G-8 would also maintain its promise to duplicate the aid to Africa to 50,000 million dollars for the 2010, adopted in its appointment in Gleneagles (Scotland) in 2005, said a source of the group. But ” ” the countries still are divididos” on the calendar of other commitments with Africa, mainly the date limit for the payment of 60,000 million dollars to fight against AIDS and the malaria, announced in the summit of the 2007,+ G-8 of Michelle Foss, economist specialized in energy, calculates that the G8 can raise effective measures to medium and long term in relation to the price of the energy, as long as their commitments and recommendations are acts of political value more than of political speed. Some experts and legislators have blamed to the financial speculators by the increasing increase of the price of petroleum, but Foss, that directs to the Center of Economy Energetics in the University of Texas, in Austin, said to the Informed Service from Washington that, even though that outside certain one, are other important reasons for the increase of the price of petroleum, as they are ties to the power supplying and subsidies in the consuming petroleum countries. It is possible that the G8 can make change medium term the markets of petroleum, if it puts on the table those controverted subjects. If the United States showed determination to seriously consider the subject of the perforation in those areas, could diminish the pressure in the price of petroleum, commented Foss. It is necessary to be pending on the conclusions, agreements that will leave this Summit, which we trusted must be to the benefit of all, of the poorest countries especially, we will already be in contact with the enemy on these conclusions..
