What's Behind Iran's Fuel Shipment to Venezuela? Mehdi Jedinia WASHINGTON - The arrival in Venezuela of five Iranian oil tankers is expected to ease the South American nation's gasoline crisis, while challenging U.S. sanctions targeting both countries. The Iranian fuel tankers began arriving in Venezuela last week under the protection of Venezuelan military forces, with the fifth cargo reportedly arriving on Sunday. Venezuela's oil sector has been acutely damaged by years of political and economic instability. Iran says the fuel shipment provided to Venezuela is about 1.53 million barrels of gasoline and petrochemical components. U.S. sanctions imposed on Venezuelan state-owned oil company PDVSA also have crippled Venezuela's ability to import certain types of fuel from abroad, but the government of President Nicolas Maduro has turned to Iran for refining parts and fuel. On Saturday, Venezuelan officials announced that the Iranian gasoline has arrived at hundreds of gas station across the country. "Venezuela has the right to buy in the world whatever it wants to buy," Maduro said in a recent speech. "Fortunately, Venezuela has more friends than what people can imagine." Defying Washington Iran and Venezuela are under U.S. economic sanctions, which has brought the two countries closer economically and politically. "Iran and Venezuela have always supported each other in times of difficulty," Venezuelan foreign minister Jorge Arreaza said in today last week, adding that, "Today we see the fruits of the multipolar world, of our Bolivarian Diplomacy for Peace and South-South Cooperation." The South-South cooperation refers to the technical cooperation among developing countries in the Global South, including the sharing of skills and resources. Some experts believe that the Iranian move to transport oil to Venezuela is a show of defiance against the U.S. by the two allies. .
