US State Department spokeswoman Jen Psaki has said that the United Nations Security Council would endorse any final nuclear agreement between Iran and the P5+1 group.
"We would anticipate that, if we're able to reach a joint comprehensive Plan of Action between the P5+1 and Iran, an endorsement vote would be held by the UN Security Council," Psaki told reporters on Friday.
She added that Washington’s unilateral restrictions imposed against Tehran would be in place, even if the UN Security Council decides to ease its sanctions on the country.
Iran and the P5+1 group -- the US, Britain, France, China, Russia, and Germany -- are currently working to complete the outlines of a nuclear deal by the end of March after they reached an interim agreement in November 2013.
The two sides have by the end of June to clinch a final agreement.
