British Foreign Secretary Jeremy Hunt has met with his Iranian counterpart, Foreign Minister Mohammad Javad Zarif, in the Iranian capital Tehran for talks that were expected to focus on a 2015 multilateral nuclear deal with the Islamic Republic.

The British official arrived in the Iranian capital earlier on Monday and later met with Zarif.

IRNA reported that Hunt would also meet with Secretary of Iran’s Supreme National Security Council (SNSC) Ali Shamkhani.

Later on Monday, Zarif posted a tweet on his official Twitter account saying that the 2015 nuclear deal between Iran and the P5+1 group of countries, officially known as the Joint Comprehensive Plan of Action (JCPOA), ways of maintaining it, and the crisis in Yemen were major items on the agenda of his talks with Hunt.

The Iranian foreign minister added that the two sides also discussed Europe’s commitment to normalize economic relations with Iran.

Secretary Hunt is the first Western official of his rank to visit Iran since the United States — formerly a party to the deal — unilaterally withdrew from the agreement in May.

The administration of US President Donald Trump had been hoping to get the other parties to the deal with Iran to likewise scrap the deal. Instead, they have stressed that not only will they stick to the agreement but that they will also work to sustain it in the face of increased US pressure.

In a statement ahead of the visit, Hunt called the Iran deal “a vital component of stability in the Middle East.”

“It (the Iran nuclear deal) needs 100 percent compliance though to survive,” the British foreign secretary stressed. “We will stick to our side of the bargain as long as Iran does.”

Just last week, the International Atomic Energy Agency (IAEA) confirmed that Iran continues to adhere to all of its obligations under the JCPOA, despite the US pullout, which also entailed the restoration of unilateral sanctions on Iran and the countries doing business with it.

The IAEA is tasked with monitoring the technical aspects of the deal. It is yet to post its latest verification and monitoring report on Iran on its website, but Reuters has obtained a copy and reported its content.

Iran’s partners in the deal, namely the UK, France, Russia, China, Germany, and the European Union (EU), have been working on a financial mechanism that would bypass the American monetary system and enable direct and secure payments to the Islamic Republic, including for oil purchases, which the US sanctions have attempted to hinder.

That mechanism, known as the Special Purpose Vehicle, will likely be one topic of discussion between Hunt and Zarif.

Hunt also plans to discuss what he has said are “destabilizing activity by Iran” in the region and the case of British nationals imprisoned in Iran on espionage charges.
