Deputy Foreign Minister Abbas Araqchi offered the framework to IAEA Director General Yukiya Amano in a Monday meeting ahead of the talks.
Araqchi was positive about the discussion, saying that the proposals coming two weeks after high-level talks between the Islamic Republic and the 5+1 Powers in Geneva, and just ahead of technical discussions offered a way forward and that Iran is ready to respond to all IAEA questions and ambiguities in a short period of time.
The reduction from about $100 per barrel to about $90 may be part of a $3.6 billion line of credit extended by Tehran to the Assad regime this spring.
The 10% discount was confirmed in a letter of May 12 from the Managing Director of Sahand Naft Iran, which co-ordinates Iranian oil and petrochemical distribution, to the President of Syrias oil company Sytrol.
