Iran is in the process of building up its nuclear weapons capacity and it is urgent that Tehran and Washington return to a 2015 nuclear agreement, France's foreign minister argues.
Iran has been accelerating its breaches of the nuclear deal and earlier this month started pressing ahead with plans to enrich uranium to 20 per cent fissile strength at its underground Fordow nuclear plant. That is the level Tehran achieved before striking the deal with world powers to contain its disputed nuclear ambitions.
Iran's breaches of the nuclear agreement after President Donald Trump withdrew the United States from it in 2018 may complicate efforts by President-elect Joe Biden, to rejoin the pact.
"The Trump administration chose what it called the maximum pressure campaign on Iran. The result was that this strategy only increased the risk and the threat," French foreign minister Jean-Yves Le Drian told the Journal du Dimanche newspaper.
"This has to stop because Iran and - I say this clearly - is in the process of acquiring nuclear (weapons) capacity."
The agreement's main aim was to extend the time Iran would need to produce enough fissile material for a nuclear bomb, if it so chose, to at least a year.
Western diplomats have said Iran's repeated breaches have already reduced the "breakout time" to well below a year.
Iran denies any intent to weaponise its nuclear program.
With presidential elections in Iran due in June, Le Drian said it was urgent to "tell the Iranians that this is enough" and to bring Iran and the United States back into the accord.
Biden has said he will return the United States to the deal if Iran resumes strict compliance with it. Iran says US sanctions must be lifted before it reverses its nuclear breaches.
However, Le Drian said that even if both sides were to return to the deal, it would not be enough.
"Tough discussions will be needed over ballistic proliferation and Iran's destabilisation of its neighbours in the region," Le Drian said.
