Iran hails European decision not to criticise it at IAEA
But diplomats said the resolution, which had not yet been formally submitted to the UN nuclear watchdog, would no longer be put forward.
"Iran hopes the parties participating in the agreement can seize this opportunity, with serious cooperation, to ensure the full implementation of the agreement by all," he added.
The latest moves come at a delicate moment for diplomacy on the Iranian nuclear issue, with fragile efforts underway to revive the ailing 2015 deal between Iran and world powers on its nuclear programme.
Ahead of the meeting, the Iranian authorities had warned the adoption of such a resolution at the IAEA could harm efforts by it and the international community to save the accord.
The deal, known formally as the Joint Comprehensive Plan of Action, has been unravelling since former US president Donald Trump pulled the United States out of the agreement in 2018.
