"After the authorisation from the US administration to Boeing, we have invited the company to begin talks on developing the country's air fleet," Akhoundi said, without giving a date, quoted by state television news agency IRIB.
Akhoundi's deputy, Asghar Fakhrieh Kashan, told AFP: "We never closed the doors to Boeing, and we are ready for negotiations whenever they come."
Boeing said on February 19 it had received authorisation from the US administration -- despite the lack of Washington-Tehran diplomatic ties for more than three decades -- to study the commercial plane market in Iran, in the wake of the lifting of nuclear sanctions in mid-January.
The orders -- mostly in the form of hire purchase -- also include 50 planes from Brazil's Embraer, the world's third biggest commercial manufacturer, and up to 40 aircraft from Europe's ATR which builds turboprop aircraft.

Kashan has said the Airbus deal alone -- for 73 long-haul and 45 medium-haul aircraft -- is worth between USD 10 and USD 11 billion. The planes -- worth as much as USD 25 billion at list prices -- are to be delivered over the next four years.
Before the nuclear deal with world powers under which Iran has curbed its atomic programme in return for a lifting of international sanctions, an embargo dating from 1995 prevented Western manufacturers from selling equipment and spare parts to Iranian companies.
The restrictions, which have been blamed for crippling the industry, were partly lifted by an interim agreement on Iran's nuclear programme that came into force in January 2014.
This allowed for the sale of spare parts, although direct sales of aircraft remained banned.
