A US delegation will visit Iran to review energy investment opportunities while Tehran negotiates a final deal with world powers on its nuclear program, a senior oil ministry official told Mehr news agency on Monday.
The United States has imposed sanctions on Tehran which prohibit Americans from trading directly or indirectly with Iran's oil sector, government or individuals connected to the sector, including any financing.
US companies are also prevented from investing in Iran's oil and gas industries or trading with them.
"It is forecast that by the visit of (the) American delegation this week and in the case of lifting sanctions on Iran's oil industry, we will witness involvement of major international American oil and gas companies in Iran in the future," said deputy Oil Minister Abbas Sheri-Moghaddam.
