While addressing the leaders of 50 Muslim-majority countries on Sunday afternoon in his first speech on a foreign soil, Trump, called on the Middle-eastern countries to combat the crisis of Islamic extremism emanating from the region.
White House aides have also tried to play down expectations for significant progress on the peace process during Trump's stop, casting the visit as symbolic.
The US has no other way but to think of "a win-win approach vis-a-vis Iran, otherwise they will fail", he said. "Trump, in his address at the Riyadh Summit, repeatedly slammed Iran claiming that it funds arms, trains militias that spread destruction and chaos" and pointed to Iran's support for Syria's Bashar al-Assad as he committed "unspeakable crimes".
Rouhani, who defeated hardline challenger Ebrahim Raisi in Friday's presidential election, responded by ridiculing decades of U.S. strategy in the Middle East.
He made the remarks at a news conference with Saudi Foreign Minister Adel al-Jubeir in Riyadh.
Asked whether he could envisage ever phoning Zarif - something former Secretary of State John Kerry did frequently during and after the negotiations that produced the nuclear deal - Tillerson replied, "I've never shut off the phone to anyone that wants to talk or have a productive conversation".
Asked about the possibility of direct talks with the U.S. over the mutual issues, the Iranian President said that "we are waiting for the USA new administration to settle, so that we could have accurate view about the ruling group in Washington".
BA cancels all flights from Heathrow, Gatwick
The airline had issues with its online check-in systems in September and July past year , causing severe delays for passengers. The shutdown is particularly problematic because it falls on a holiday weekend when thousands of Britons are traveling.
White House is 'not going to comment on Jared' Kushner
It covers materials such as emails, phone records and documents dating to Trump's first days as a candidate in July 2015. Kushner initially failed to declare the meetings on forms to obtain a security clearance to serve in the White House .
Trump began his trip this weekend in Saudi Arabia, where he gave a speech revealing a more measured stance towards Islam compared to much of his campaign rhetoric, as well as a turn away from the Obama-era policies towards the region. The Arab Spring uprisings of 2011 showed again the instability created by unreconstructed authoritarian rule in the region.
"Small and weak countries that could not imagine a fight with Iran, are now publicly talking about forming a military alliance against it". The flight symbolized his attempt to unify two nations that have no diplomatic relations in a bigger fight against Iran. "You just need a small trigger that can escalate the situation on the ground".
"Who can say regional stability can be restored without Iran?"
He said: "Terrorists don't worship God".
Ivanka Trump, the president's daughter and senior adviser, was more direct during an entrepreneurship roundtable with Saudi women Sunday morning, telling the participants that in every country, "women and girls continue to face unique systematic, institutional, cultural barriers, which hinder us from fully engaging in and achieving true parity of opportunity within our communities".
But the policy could be counter-productive, he said.
