Vienna--Although Iraq's decided to stop oil deliveries  , the 11-nation Organization of Petroleum Exporting Countries (OPEC)   will not increase production to make up the shortfall   caused by Iraq.     The 11 oil ministers   decided to meet again on July 3 to discuss the effects of the Iraq temporary   stop. The organization's president Charkid Khelil of Algeria said after the meeting that stocks   were high and prices were stable   and that quota   increases were not necessary.     The EU Commission   has also expressed concern about Iraq's output stop. A speaker said OPEC had to take all possible measures to keep or lower the oil price.     Saudi Arabia's Oil Minister Ali Al-Nuaimi had earlier said that there would not be any shortfall of oil in the market. The organization had already taken steps to fill the gap  , he said. OPEC Secretary General Ali Rodriguez added that the period of the Iraq stop to export was not known, so other exporters were not going to lift quotas yet. If the market was destabilized  , a suitable response   would be made.     Iraq stopped delivery of crude oil   on Monday to protest   against the UN Security Council's   decision to extend   the oil-for-food program by only a month, instead of the normal six-month renewal  .
