Iran´s Rouhani warns Macron of looming nuclear step

TEHRAN: President Hassan Rouhani spoke with French counterpart Emmanuel Macron Saturday, warning him Iran would take the next step in reducing its nuclear commitments unless Europe lives up to its own undertakings.

Tensions have spiked in the Gulf since May last year when President Donald Trump unilaterally withdrew the US from a nuclear deal between Iran and world powers -- known formally as the Joint Comprehensive Plan of Action (JCPOA).

Ships have been attacked, drones downed and oil tankers seized in the Gulf in recent months.

Macron has been leading efforts to de-escalate the situation and he expressed hopes of bringing together Rouhani and Trump for a meeting during a G7 summit days ago.

But Rouhani has downplayed the likelihood of that happening unless the United States first lifts crippling sanctions that it has slapped on Iran since pulling out of the deal.

"If Europe cannot operationalise its commitments, Iran will take its third step to reduce its JCPOA commitments," Rouhani reportedly told Macron in the phone call.

However, "this step, just like the other ones, will be reversible," he added, quoted on the Iranian government´s website.

"Unfortunately after this unilateral move by the US, European countries did not take concrete measures to implement their commitments," he continued.

"The contents of JCPOA are unchangeable and all parties must be committed to its contents," he said.

Rouhani said Iran had two priorities: for all parties to the JCPOA to fully implement their obligations and "securing the safety of all free maritime transportation in all waterways including the Persian Gulf and Strait of Hormuz".

Twelve months on from the US pulling out of the nuclear deal, Iran began reducing its commitments.

The UN´s nuclear watchdog, the International Atomic Energy Agency, said Friday that just over 10 percent of Iran´s uranium stockpile was now enriched up to 4.5 percent, above the 3.67 percent limit stipulated in the 2015 deal.

It also said Iran´s total stockpile of uranium, which under the accord should be no more than the equivalent of 300 kilogrammes (661 pounds) of uranium hexafluoride, now stood at roughly 360 kilogrammes.

Iran has not specified what its third step might be in reducing its commitments to the deal.

Foreign Minister Mohammad Javad Zarif said in a recent interview with the Sueddeutsche Zeitung newspaper that the step would be taken on September 6.
