The US and its allies are planning a new round of sanctions against Iran to test "how high Iran's pain threshhold is" and to further pressure Teheran into ending its uranium enrichment program, The New York Times quoted the chief US nuclear adviser as saying on Friday.
US President Barack Obama's coordinator for weapons of mass destruction, Gary Samore, was skeptical about Iran's sincerity in nuclear talks between the Islamic Republic and western nations that were relaunched in Vienna just three days ago.
"[Iran] believes it can manipulate the appearance of negotiations to weaken existing sanctions and avoid additional measures," Samore stated at a conference held by the Foundation for the Defense of Democracies.
“This ploy will not work,” Samore said. “In the wake of the Geneva talks, we and our allies are determined to maintain and even increase pressure. We need to send the message to Iran that sanctions will only increase if Iran avoids serious negotiations and will not be lifted until our concerns are fully addressed,” he added.
