Iran warned on Tuesday that New US sanctions against the Islamic Republic were negative and could adversely affect the nuclear talks scheduled for next month with world powers.
"We consider any kind of sanction as negative and a wrong step," foreign ministry spokesman Ramin Mehmanparast said in his weekly briefing.
"Any decision by Western officials, including the Americans, can affect the atmosphere of talks," he said.
A day earlier, US President Barack Obama announced measures aimed at preventing Iran, and Syria, from acquiring surveillance software and monitoring equipment to control its population.
Obama's executive order was announced ahead of May 23 talks to be held in Baghdad between Iran and the P5+1 group comprising the United States, Russia, China, France, Britain and Germany.
Iran and the P5+1 met in Istanbul on April 14 to revive talks that had been stalled for 15 months, and agreed to hold the more substantive round of negotiations in the Iraqi capital.
