He also said that Tehran would ramp up its defence capabilities, including its missile programme, if the U.S. undermined a nuclear deal between Iran and Western powers.
During the meeting, they exchanged views on the latest political developments related to the nuclear agreement between Iran and six world powers sealed in July 2015 and implemented in December 2016.
On Sunday, Iranian Foreign Minister Mohammad Javad Zarif said that his country would give a "response fitting" any stance adopted by Trump on the historic nuclear accord. United States officials insist this will not sink the deal itself but open the way for Congress to develop new measures to punish other aspects of Iran's behavior.

The refusal to certify kicks the issue to Congress, opening a 60-day period for debate.
On Monday, former Israeli Defense Forces military chief Amos Yadlin, who is also the head of the Institute for National Security Studies (INSS), co-authored an essay with his INSS fellow and former National Security Council official Avner Golov, urging the US President against leaving the agreement.
This may be a fairly simple task in light of the rhetorical responses given to the U.S. and its allies by various Iranian officials in the wake of new enforcement measures or even hints of the same.

In his 19 September speech at the UN General Assembly, Trump called the deal "one of the worst and most one-sided transactions the United States has ever entered into".
"We are looking with great concern towards the United States", Gabriel told reporters in Berlin. The U.S. ability to shoot down one intercontinental ballistic nuclear missile launched from either of these countries is at best 50-50. Successfully negotiating a supplemental agreement will also require offering incentives such as reinstating so-called U-turn transfers for Iran through the US financial system, or cooperation on civil nuclear technology in exchange for Iranian concessions. This has certainly been meant to reference ballistic missile tests that flout a United Nations Security Council resolution calling on Iran to avoid work on weapons capable of carrying a nuclear warhead.
While the world waits to see whether Donald Trump will blow up the Iran nuclear deal, actress and activist Nazanin Boniadi has a message for the USA president: Stop emboldening Iranian leaders.
For months now, he has been signing off every 90 days a certificate, which, begrudgingly, accepts that Iran has stuck to its side of the so-called 'Iran deal.' Its official title is the 'The Joint Comprehensive Plan of Action, ' which, when nailed by Obama in 2015, closed off any chance that Iran could get nuclear weapons for at least a decade.
"Mrs May and the president also discussed the need for the UK, US and others to work together to counter destabilising Iranian activity in the region".More news: Investigators interview prostitutes about Vegas gunman
