Saqqayian told Brazilian officials that Tehran could easily find new suppliers of corn, soybeans and meat if the South American country refused to permit the refueling of the vessels.
“I told the Brazilians that they should solve the issue, not the Iranians,” he said in an interview at the Iranian embassy in Brasilia.
“If it’s not solved, maybe the authorities in Tehran may want to take some decision because this is a free market and other countries are available,” he added.
Saqqayian said Iran was considering sending fuel to the stranded ships, even though it would take longer and prove costly.
His remarks came as two Iranian vessels, one reportedly loaded with corn, were stranded at the port of Paranagua, unable to head back to Iran due to lack of fuel.
Iran is one of the largest grain importers from Brazil and the complication with the Iranian ships is already worrying Brazilian traders about the broader impact on trade with the Islamic Republic.
Brazil's state oil company Petrobras has said the ships, Bavand and Termeh which had brought urea to Brazil, appeared on a list of US sanctions. The company says there are other fuel companies that can supply the Iranian ships, but it has an effective monopoly on refueling services at Brazilian ports.
Brazil has emerged as a new destination for petrochemical shipments from Iran which is tapping new markets to compensate for sliding oil sales.
