Iran's transportation minister says a possible deal between the Islamic Republic and Boeing Co. could be worth as much as $25 billion. Boeing didn't immediately respond to a request for comment, but the figure would be on par with a sale already made by its European rival Airbus to Iran, the AP reports. Iranian Transportation Minister Abbas Akhoundi's remarks on state television on Wednesday are the first figures floated by Tehran about the proposed sale. The deal is believed to involve around 100 aircraft, Bloomberg reports, though Boeing is likely cautious about entering Iran's market as other sanctions remain in place against Tehran. American officials say the sale would need permission from the US Treasury. (More Iran stories.)
