Trump says Iran attack on ‘hold’: What we know about latest negotiations

While the specific proposals in the latest plan from Iran have not been made public, Baghaei said demands include the release of its assets frozen abroad and the lifting of sanctions.

“The points raised are Iranian demands that have been firmly defended by the Iranian negotiating team in every round of negotiations,” he said.

Iran has also previously demanded compensation for damage inflicted by US-Israeli attacks, an end to the ongoing US naval blockade of Iranian ports and a halt to fighting on all fronts, including in Lebanon, where Israeli forces continue daily attacks and have mounted a ground invasion in the south of the country.

Washington has urged Tehran to dismantle its nuclear programme and lift a blockade on the Strait of Hormuz, which, before the war, carried one-fifth of the world’s crude oil and liquefied natural gas ‌(LNG) supply.

What are the main sticking points between Iran and the US?

A major point of contention is Iran’s stockpile of enriched uranium. During negotiations, Washington has urged Tehran to give away its enriched uranium, a demand Tehran has resisted.

Iran is believed to have about 440kg (970lb) of uranium enriched to 60 percent. A 90 percent threshold of enriched uranium is needed to produce a nuclear weapon. Iran has never officially declared an intention to build nuclear weapons. The US wants this stock to be handed over to it, but Iran is reportedly only willing to consider handing it to a third party – if at all.

Iran’s Foreign Minister Abbas Araghchi told reporters on the sidelines of a meeting of foreign ministers from BRICS nations in New Delhi last week that Iran and the US have reached a “deadlock” on the question of Iran’s “enriched material”.

As a result, he said, the topic is being “postponed” until later stages in the talks. “For the time being, it is not under discussion, it’s not under negotiation, but we will come to that subject in later stages.”

Araghchi confirmed he had spoken to Russian officials about an offer from Moscow to store Iran’s enriched uranium. He said Iran may consider Russia’s proposal at an “appropriate time” and that he appreciates Moscow’s efforts.

“When we come to that stage, obviously we will have more consultations with Russia and see if the Russian offer can help or not,” he said.

The US and Iran are also arguing about whether Iran should be allowed to enrich uranium at all. Under the Obama-era Joint Comprehensive Plan of Action, signed with several countries in 2015, Iran was able to continue enriching to 3.87 percent – enough for the development of a nuclear power programme. Trump withdrew the US from that agreement in 2018, despite consistent reports from the International Atomic Energy Agency (IAEA) that Iran had stuck to its terms. Now, the US wants a moratorium on all uranium enrichment for a period of up to 20 years, it says.

Another sticking point between the two countries is the Strait of Hormuz in the Gulf.

Since early March, Iran has restricted shipping through the strait, a narrow waterway linking Gulf oil producers to the open ocean and through which 20 percent of the world’s oil and liquefied natural gas (LNG) supplies are shipped during peacetime. Iran has allowed passage by vessels from select countries, but they are required to negotiate transit with the Islamic Revolutionary Guard Corps (IRGC).

In its previous proposals to end the war, Iran has mentioned charging fees or tolls for vessels seeking to pass through the state. Washington has repeatedly rejected the prospect. In April, the US announced a naval blockade on ships entering or leaving Iranian ports, further adding to the disruption of global oil and gas supplies.

Iran’s state media reported, citing the Iranian Ministry of Foreign Affairs, that technical teams from Iran and Oman met in Oman to negotiate a mechanism for safe transit in the Strait of Hormuz.

A third likely major point of friction – although one which may also be kicked into later discussions – is Iran’s support for a network of “proxy” armed groups around the Middle East which it calls its “axis of resistance”. These include the Houthis in Yemen, who have also caused disruption by launching attacks on Israel-linked ships in the Red Sea in the past, Hezbollah in Lebanon and multiple groups based in Iraq and Syria.
