As regards his meetings in Iran, Badri stated that he and Iranian Oil Minister Rostam Qassemi discussed the latest developments in global economy, and described the meeting as \"very good\". \"During the meeting we emphasized that effort should be made so that we could reach an agreement in the next general meeting,\" Badri stated. Iranian Oil Minister Qassemi, too, said he expects oil prices remain unchanged by the end of this winter. \"Demand and supply in the market determine the price of oil. Although at present the price has decreased due to political and economic developments, the present price seems to remain steady by the end of winter,\" Qassemi told reporters in a news conference in Tehran on Tuesday. Qassemi further pointed to the OPEC\'s upcoming meeting on December 14 at its headquarters in Vienna, Austria, and said that before the next meeting Iran will consult with members to reach a conclusion about the oil market.
