"While it was not benefiting from the deal, no one should expect Iran to go to implement more voluntary measures", Iran's ambassador to the IAEA, Reza Najafi added.
“We gave a few weeks to our European counterparts. A few weeks means a few weeks, not a few months", Najafi concluded.
Meanwhile, IAEA chief Yukiya Amano has said the comment is “not an expression of concern or complaints but rather an encouragement to Iran”.
The three European powers that signed the deal — France, Britain and Germany — are looking to shield European companies from U.S. sanctions while also keeping Iranian oil exports and the revenue from them flowing.
In its' previous report, International Atomic Energy Agency (IAEA) approved Iran’s full compliance with its commitments within the framework of JCPOA.
US President Donald Trump officially declared America's withdrawal from the JCPOA on 8 May 2018.
Tehran has said it would make a decision on its future role in the nuclear agreement in the coming weeks following negotiations with the other signatories to the deal.
