"Our current crude oil production is 3.3 million barrels per day and by the end of September this amount will increase to 3.4 million," Javad Owji said.
In 2018, then-U.S. President Donald Trump exited a nuclear agreement and re-imposed sanctions on Tehran, whose crude oil output dropped to 2.4 million barrels per day on average in 2021.
Earlier this month, Iran announced its oil exports had surpassed 1.4 million barrels per day.
