Iran and the three European signatories to the 2015 nuclear deal held talks in Istanbul to discuss the state of nuclear and sanctions-lifting negotiations, Iranian Deputy Foreign Minister Kazem Gharibabadi said on Friday.

Gharibabadi said he and fellow Deputy Foreign Minister Majid Takht-Ravanchi hosted the political directors of the UK, France, and Germany for discussions aimed at advancing diplomatic efforts.

“Iran and the E3 are determined to sustain and make best use of diplomacy,” he wrote on X. “We will meet again, as appropriate, to continue our dialogue.”

A German diplomatic source told Iran International ahead of the meeting that discussions would focus on Iran’s nuclear program, but stressed, “These are not negotiations.” The source said Germany was represented by Dominik Mutter, Political Director at the Federal Foreign Office.

Earlier this week, Iranian Foreign Minister Abbas Araghchi said Iran remained open to talks with Europe, “even if their own policies have led to some isolation in these negotiations.”

Few details have emerged from the meeting, and no major breakthroughs have been announced.

Under the UN resolution that endorsed the 2015 nuclear deal, the three European signatories – Britain, France, and Germany – have the authority to reimpose UN sanctions on Iran through a mechanism known as the "snapback," if they determine that Tehran is not complying with the agreement.

Diplomats told Reuters that the E3 could move to trigger the snapback mechanism as early as August if no significant progress is made in negotiations. The deadline to do so under the resolution is October 18.

Separately, US Secretary of State Marco Rubio met Friday in Istanbul with the national security advisors of the UK, France, and Germany to discuss both Iran and the war in Ukraine, according to a US official and a Reuters witness.

The United States and Iran have held four rounds of indirect nuclear negotiations mediated by Oman since April. Both sides have described the talks as “constructive,” though no formal agreement has been reached.

Meanwhile, during his visit to Persian Gulf states this week, US President Donald Trump said Iran had “sort of agreed” to American terms and declared, “We’re getting very close to a deal.” Trump reiterated that Iran must never obtain a nuclear weapon and warned Tehran faces either “a very, very nice step” or “a violent step — the violence like people haven’t seen before.”

On Friday, Trump added that Iran has received a formal US proposal and must act quickly. Axios reported that the written proposal was handed to Iranian negotiators during the fourth round of talks in Oman and taken back to Tehran for consultation with senior officials.
