A senior US official later told Reuters that President Donald Trump is "very likely" to approve the recertification.
And yet, considering the wrecking ball that the Trump administration has already taken to Obama's foreign-policy legacy, and the degree to which the White House has adopted hostility to Iran as a guiding principle, the deal looks more robust on its second birthday than you might think. But that official also said the president has "reservations" and could decide not to.
Trump and Republicans in Congress have criticized JCPOA, with Trump decrying it as one of the worst deals in history.
Trump's administration certified the deal in April.
Conservative opinion magazine The Weekly Standard was the first to report the news Thursday, citing four unnamed sources.
"The Joint Comprehensive Plan of Action (JCPOA) proved that followers of the policy of pressure have finally realized its inefficiency, therefore, the U.S. should also reconsider its approach towards the agreement", Iran's IRNA news agency quoted Zarif as saying in NY.
While lifting nuclear-linked sanctions, the United States maintains sanctions related to Iran's ballistic missile program and human rights record.
"Those who imposed such pressure upon Iran, finally found out that they can't achieve what they want", asserted the Iranian top diplomat; "at the end they concluded that the agreement was the best achievement to garner, and as the nature of multilateral negotiations, all parties achieved their objectives at the end".
"The disease is broader Iranian aggression".
Other signatories have been open in their rejection of Trump's assessment of the deal and warned that they would continue to honor the deal no matter what the United States does.
Asked about those comments, European Union foreign-policy chief Federika Mogherini said at a Tuesday news conference with Russian Foreign Minister Sergey Lavrov, "I simply reply with the numbers of trade and investments from the European Union [that] have increased to Iran in terms of double digits, and this will continue.The engagement with Iran will continue, and the deal will be implemented in all of its parts by all".
"This deal belongs to the global community, having been endorsed by the United Nations Security Council, that expects all sides to keep the commitments they took two years ago", she added.
