Washington maintains strict sanctions against Iran's oil industry to try to halt the country's nuclear program. Earlier this year, Tehran sent several gasoline cargoes to Venezuela to help it overcome fuel shortages, as well as equipment to help state oil company PDVSA repair its dilapidated refineries.
"We are helping each other," Maduro said in an interview broadcast on state television. "I think the Iranian experience will help us reinforce our management capacity." He did not provide further details of how Iran was helping, noting he should maintain "silence since we are in a war."
The growing ties between Iran and Venezuela are concerning other countries in the region. Colombian President Ivan Duque said this week Maduro was eyeing missile purchases from Iran, which Venezuelan officials denied.
But in the interview, Maduro said Duque's statement was a "good idea" he had not yet considered. "If it is possible and convenient, we will buy those missiles," he said.
