According to PIN, Masoud Mir-Kazemi added that Iran can cope with any sanctions targeting its fuel imports.
He also cited that the move to raise output by 14 million liters per day increased total output to 58.5 million liters regarding domestic output at 44 million liters a day.
The higher production level, carried out at three southern petrochemical plants, would only last for a few days, he said, making clear it was not economical in the long run.
"With this move we would like to show that the West can not use any limitations on selling gasoline to Iran as a tool against the Islamic Republic," Mirkazemi told a news conference.
He also said Iran faced no problems in importing gasoline as it had a good list of suppliers. It also had at least 1.5 billion liters in storage at all times.
"We are not going to disrupt petrochemical production in our petrochemical units. We just want to show that they can not use this tool to pressure Iran," Mirkazemi said.
In the longer term, work was under way to boost capacity at existing refineries by 33.5 million liters per day by 2013, he said. In addition, a new refinery to be completed by 2014 would produce 35 million liters.
