"Undoubtedly, cooperation among the aligned countries in the OPEC can both defuse the plots of certain powers against the organization and help stabilize an acceptable price for oil in 2015," the agency quotes Rouhani as saying in a meeting with his Venezuelan counterpart Nicolás Maduro in Tehran on Saturday.
Maduro also urged other oil exporting countries for cooperation in order to return stability to oil prices, according to the Venezuelan Noticias24 newspaper.
Earlier in November, while meeting with Venezuelan Foreign Minister Rafael Ramirez in Tehran, President Rouhani already underlined the need for cooperation between Tehran and Caracas to help stabilize the crude prices in the global markets in a bid to prevent instability of the international economy.
"The sudden fluctuations in oil prices (negatively) influence the stability of the global market and hence we should try to maintain balance in oil prices," the agency quotes the Iranian president as saying at that meeting.
The oil prices have fallen dramatically since June 2014 and now stand at $50 per barrel.
On Wednesday, the price for Brent crude fell below $50 per barrel, marking the lowest point since 2009 and a 50 percent drop from summer 2014 levels. Amid the indications of the US oil reserves reduction, the prices increased for a couple of days, however on Friday continued to drop.
Oil exporting countries, including Venezuela, Iran and Russia have faced significant economic problems due to the low prices on crude.
The Iranian head of state also stressed that both countries are opposed to terrorism and extremismin the world and help each other in the establishment of stability and security across the world.
And also called for the further development of bilateral relations in trade, investment, exports of technical and engineering services, medical industries, ship-building and direct flights between the two countries.
