WASHINGTON - The six world powers negotiating with Iran over its nuclear program would consider limited pullback of sanctions in exchange for clear evidence that Tehran is taking steps to halt the advance of its nuclear program, the White House said on Thursday.
In exchange for "concrete, verifiable measures" to address long-standing international concerns, the six powers "would consider limited, targeted, and reversible relief that does not affect our core sanctions architecture," White House spokesman Jay Carney told reporters at a briefing.
The broader sanctions regime would be maintained until there is a "final, comprehensive, verifiable" agreement that resolves international concerns, he said.
If Iran failed to show progress on its nuclear program, the modest sanctions relief could be reversed, and stiffer sanctions could be imposed, Carney said.
