The U.N. Security Council voted June 9 to place new sanctions on Iran that allow for searches of banned goods in cargo to or from Iran and increases the number of individuals and companies subject to travel bans and an asset freeze.
Mehdi Ghazanfari, the Iranian commerce minister, was quoted by the semiofficial Mehr News Agency as saying Iran had the right to respond to the inspections.
"Iran reserves the right to respond to inspections as any such attempts will be a move beyond the sanctions resolution," Mehr news agency reported on Friday.
Iranian President Mahmoud Ahmadinejad said in June that Tehran reserved the right to defend its international rights.
"We reserve the right of retaliation for ourselves ... we are able to defend our rights," he said.
Iranian opposition leader Mehdi Karroubi said sanctions on Iran would backfire, bringing in profits for the Islamic Revolutionary Guard Corps.
