Donald Trump has offered to meet Iran’s leaders with “no preconditions” and “any time they want”.
“I’d meet with anybody. I believe in meetings,” the US president told reporters at the White House.
Mr Trump’s conciliatory approach comes after he and Iranian President Hassan Rouhani traded hostile warnings earlier this month.
In May, the US left a deal which curbed Iran’s nuclear activities in return for the lifting of international sanctions.
Washington is preparing to re-impose sanctions on Tehran within days – despite objections from the UK, France, China, Russia and Germany, which also signed the 2015 agreement.
The US is deeply suspicious of Iranian activity in the Middle East and is an ally of Israel and Saudi Arabia, two of Iran’s foes.
“If they want to meet, we’ll meet,” Mr Trump said.
Such a meeting would be the first between US and Iranian leaders since before the 1979 Iranian revolution. In 2013 Mr Rouhani spoke on the phone with President Obama after declining an offer to meet him on the sidelines of the UN General Assembly.
Mr Trump’s abrupt change in tone also echoes the run-up to his meeting with North Korean leader Kim Jong-un, another diplomatic first, which took place after the two leaders had previously traded insults and threats.

Shortly afterwards Secretary of State Mike Pompeo said he would support a meeting if Iran showed it was willing to change its behaviour.
The “president wants to meet with folks to solve problems”, he told CNBC.
Last week Mr Trump responded angrily to Mr Rouhani, who had earlier warned of the consequences of a conflict with his country.
Mr Trump tweeted in capitals that Iran would “suffer consequences the likes of which few throughout history have ever suffered before” if it threatened the US.
Mr Rouhani had told Iranian diplomats: “America should know that peace with Iran is the mother of all peace, and war with Iran is the mother of all wars.” His remarks were reported by Iran’s state news agency IRNA.
To Iranian President Rouhani: NEVER, EVER THREATEN THE UNITED STATES AGAIN OR YOU WILL SUFFER CONSEQUENCES THE LIKES OF WHICH FEW THROUGHOUT HISTORY HAVE EVER SUFFERED BEFORE. WE ARE NO LONGER A COUNTRY THAT WILL STAND FOR YOUR DEMENTED WORDS OF VIOLENCE & DEATH. BE CAUTIOUS!

Responding to Mr Trump’s broadside, Iranian Foreign Minister Javad Zarif tweeted: “Color us unimpressed.”
COLOR US UNIMPRESSED: The world heard even harsher bluster a few months ago. And Iranians have heard them —albeit more civilized ones—for 40 yrs. We’ve been around for millennia & seen fall of empires, incl our own, which lasted more than the life of some countries. BE CAUTIOUS!

n May Mr Pompeo laid out 12 conditions for any “new deal” with Iran, including the withdrawal of its forces from Syria and an end to its support for rebels in Yemen.
What do the US and Iran disagree on?
- Mr Trump has consistently opposed the 2015 nuclear deal, which saw the US release billions of dollars of frozen assets in exchange for curbs on Iran’s nuclear programme
- The Trump administration regards Iran as a destabilising force in the Middle East, arguing the nuclear deal enabled Iran to pursue a more assertive regional policy. Iran has sent hundreds of troops and thousands of volunteer militiamen to Syria, and has strengthened its military presence there
- Gulf states have accused Iran of backing Yemen’s Houthi rebels with both money and weapons, though Iran has denied this. Saudi Arabia, a key US ally, is a major adversary of Iran and has repeatedly warned about Iran’s intentions
Why did the US withdraw from the nuclear deal?
In May, Mr Trump called the nuclear accord – or Joint Comprehensive Plan of Action (JCPOA) – a “horrible, one-sided deal that should have never, ever been made”.
He alleged that the deal did not restrict Iran’s “destabilising activities” in the region enough.
Analysts also cited the influence of White House Iran hawks including Mr Pompeo and US National Security Adviser John Bolton, and Mr Trump’s tendency to target major policies of his predecessor President Obama.
Iran insists its nuclear programme is entirely peaceful, and its compliance with the deal has been verified by the International Atomic Energy Agency (IAEA), which has said Iran is honouring its commitments.
The IAEA has said its inspectors were granted access to all locations they needed to visit in 2017, but that they did not seek to enter any military sites, which Iranian officials declared off-limits – a move the US said raised doubts over Tehran’s compliance.
Iran is one of the world’s largest oil producers, with exports worth billions of dollars each year.
It is already feeling economic pressures, and has seen large-scale protests over rising prices and a decline in the value of its currency, the rial.
