Iran's economy will not be affected by sanctions imposed by the United Nations, even if Japan goes along with them, visiting Iranian Deputy Foreign Minister Mohammadali Fatollahi said in Tokyo Friday.

"The Iranian economy is self-sufficient," Fatollahi asserted at a press conference at the Iranian Embassy in Minato Ward. "I don't see much difference in sanctions we were under before and we will be from now on. As we anticipated (sanctions), it won't have much effect" on the economy, even if Japan follows the U.S., he said.

On June 9, the U.N. Security Council adopted a resolution to impose fresh sanctions on Iran over its nuclear program.
