Trump, who generated controversy with his push to ban many Muslims from entering the United States, described the fight against terrorism as a battle between good and evil rather than a clash of civilizations. "This is a battle between barbaric criminals who seek to obliterate human life, and decent people of all religions who seek to protect it.This is a battle between good and evil".

Among the deals signed on Saturday, GE said it reached $15 billion of agreements involving nearly $7 billion of goods and services from GE itself.

Introduced by Saudi Arabia's King Salman, who said he did not blame the people of Iran for the regime that "violated principles of global law", Trump made a 33-minute speech that encouraged people to unite against Islamist militants.

He said his administration would instead be offering partnership based on shared interests and values.

Trump's address Sunday was the centrepiece of his two-day visit to Saudi Arabia, his first stop overseas as president. But on Sunday he avoided that kind of Islamophobic rhetoric, and specifically the phrase "radical Islamic terrorism", which he had often trumpeted at rallies.

She noted that Trump on Saturday signed a $110 billion arms deal with Saudi Arabia, a key objective of the visit.

While Riyadh is likely to welcome Trump's tough talk on Iran in his speech, he has yet to follow through on his election pledge to renegotiate the Iran nuclear deal struck by his predecessor and worldwide allies.

The ebullient welcome reflected a kingdom eager to rekindle its relationship with the United States, and to use the visit to declare and solidify its own leadership role in the Muslim world. Trump's visit also coincided with the Saudi-US CEO Forum and Tweeps 2017. In an interview with Fox Business Network last March following a series of attacks in Brussels, Trump said, "we're having problems with the Muslims", adding, "You need surveillance, you have to deal with the mosques whether we like it or not".

The fund, which will be run by World Bank, not Ivanka Trump, aims to provide to female entrepreneurs with financial support in the form of capital and access to networking and financial markets, something Trump says she anticipates will be important to the future growth of women.

Moreover, there are political factors involved in the attraction to extremism, which is indelibly linked to the autocracy that festers throughout much of the Arab world - in his speech, Mr. Trump drew no attention to that whatsoever. "He denied the Palestinian people the right to resist, which is a legitimate and sacred right to liberate the land and holy places".

Earlier, Saudi Arabia's King Salman bin Abdulaziz accused regional rival Iran of exporting extremist Islamic movements to the world and vowed to eliminate the Islamic State group.

This is Trump's first foreign trip as president, and he delivered the address to leaders of dozens of Arab and Muslim-majority nations. Or indeed, Mr. Trump himself, when he proclaimed, "I think Islam hates us"?

His Secretary of State Rex Tillerson set the tone on Saturday when he urged Iran's newly re-elected President Hassan Rouhani to dismantle his country's "network of terrorism".

President Trump slammed Iran for spreading "destruction and chaos" through the region.
