Iran says it is preparing to unveil an agreement with Boeing for the supply of jetliners.
According a June 13 statement on the Ministry of Roads and Urban Development website, Minister Abbas Akhoundi in an address to parliament referred to a Boeing deal "within the coming days."
Western and Middle East sources were quoted as saying that the deal would involve flag carrier Iranair acquiring more than 100 Boeing jets, both directly from Boeing and from leasing companies.
The Islamic republic is emerging from international isolation after the easing of sanctions in January under a deal between Tehran and global powers to curb Iran's nuclear program.
Tehran has long said it will need to revamp an aging fleet, hit by a shortage of parts because of trade bans imposed by Washington and other Western powers.
Europe's Airbus announced this year a provisional accord with Iran for 118 jets worth $27 billion.
Both Airbus and Boeing would need require U.S. government approval to finalize their deals.
