G7 leaders will discuss the prospect of reviving the Iran nuclear talks after the European Union's foreign policy chief met senior officials in Tehran, a French presidency official said on Sunday.

Iran's indirect talks with the United States on reviving the 2015 nuclear pact will resume soon, the Iranian foreign minister said on Saturday amid a push by Josep Borrell to break a months-long impasse.

The official said discussions would take place on Sunday at a dinner between the leaders of the Group of Seven rich nations with more detailed talks taking place on Tuesday morning between France, Britain, Germany and the United States.

The three European powers are parties to the nuclear deal, which then-US President Donald Trump pulled out of in 2018.

The pact appeared close to being revived in March after 11 months of talks, when the process came to a halt. Tehran insisted that Washington remove the Islamic Revolutionary Guard Corps (IRGC), its elite security force, from the U.S. Foreign Terrorist Organization list.

"Talks have intensified between our teams," said the French official, adding that it was crucial to revive the pact for the nuclear non-proliferation benefits, regional security and also to see how it all fits into the question of high oil prices.

Israel has reportedly critized Borrell's trrip to Tehran and the revivial of the JCPOA, which it regards as inadequate in preventing Tehran from acquiring nuclear weapons.
