Iran weighs nuclear diplomacy with US; gaps over missiles remain

Iran is weighing the terms for resuming talks with the US soon, a foreign ministry official said on Monday, after both sides signalled readiness to revive diplomacy over a long-running nuclear dispute and dispel fears of a new regional war.

Tensions are running high amid a military buildup by the US. Navy near Iran, following a violent crackdown against anti-government demonstrations last month, the deadliest domestic unrest in Iran since its 1979 revolution.

US. President Donald Trump, who stopped short of carrying out threats to intervene during the crackdown, has since demanded Iran make nuclear concessions and sent a flotilla to its coast. He said last week Iran was “seriously talking”, while Tehran’s top security official Ali Larijani said on X that arrangements for negotiations were underway.

Iranian sources told Reuters last week that Trump had demanded three preconditions for resumption of talks: Zero enrichment of uranium in Iran, limits on Tehran’s ballistic missile program and ending its support for regional proxies.

Iran has long rejected all three demands as unacceptable infringements of its sovereignty, but two Iranian officials told Reuters its clerical rulers see the ballistic missile programme, rather than uranium enrichment, as the bigger obstacle.

Foreign Ministry spokesperson Esmaeil Baghaei said Tehran was considering “the various dimensions and aspects of the talks”, adding that “time is of the essence for Iran as it wants lifting of unjust sanctions sooner.”

A senior Iranian official and a Western diplomat told Reuters that US. Special Envoy Steve Witkoff and Iranian Foreign Minister Abbas Araghchi could meet in Turkey in the coming day.

A Turkish ruling party official told Reuters that Tehran and Washington had agreed that this week’s talks would be focused on diplomacy, a potential reprieve for possible U.S. strikes.

The Iranian official said “diplomacy is ongoing. For talks to resume, Iran says there should not be preconditions and that it is ready to show flexibility on uranium enrichment, including handing over 400 kg of highly enriched uranium (HEU), accepting zero enrichment under a consortium arrangement as a solution”.

However, he added, for the start of talks, Tehran wants US. military assets moved away from Iran.

“Now the ball is in Trump’s court,” he said.

Tehran’s regional sway has been weakened as by the ousting of Iran’s close ally, Syrian dictator Bashar al-Assad.

Last year the US struck Iranian nuclear targets, joining in at the close of a 12-day Israeli bombing campaign.

TEHRAN DEMANDS LIFTING OF SANCTIONS

After five rounds of talks that have stalled since May 2023, several hard-to-bridge issues remained between Tehran and Washington, including Iran’s insistence on maintaining uranium enrichment on its soil and refusal to ship abroad its entire existing stockpile of highly enriched uranium.

Since the US. strikes on Iran’s three nuclear sites in June, Tehran says its uranium enrichment work has stopped. The U.N. nuclear watchdog has called on Iran repeatedly to say what happened to the HEU stock since the June attacks.

Western countries fear Iran’s uranium enrichment could yield material for a warhead. Iran says its nuclear programme is only for electricity generation and other civilian uses.

The Iranian sources said Tehran could ship its highly enriched uranium abroad and pause enrichment in a deal that should also include lifting economic sanctions.
