The U.S. president claims he has signed a $100 trillion deal during his visit to Saudi Arabia, Qatar and the UAE.

President Donald Trump praised the relationship between the United States and the United Arab Emirates and said the latter will invest $1.4 trillion in the former's artificial intelligence sector over the next decade.

"I absolutely have no doubt that this relationship will only get bigger, better," Trump said in a meeting with UAE President Sheikh Mohamed Bin Zayed Al Nahyan on Thursday.

Sheikh Mohammed said the UAE remains “committed to working with the United States to promote peace and stability in our region and globally”.

The agreement with the UAE is expected to enable Gulf countries to build data centers that are crucial to developing AI models. These countries have not said which AI chips can be included in the UAE data center. NVIDIA CEO Jensen Huang earlier spoke with Sheikh Mohamed and Trump.

The White House said the AI ​​agreement “includes UAE’s commitment to investing, building or investing in U.S. data centers, at least as powerful and powerful as the UAE.”

Al Jazeera's Hashem Ahelbarra reported in Doha, Qatar that the deal was a "national security concern" in Washington in the past. "But then they decided to change Trump's mind, especially when the UAE expressed willingness to invest $1.4 trillion," he said.

Ahelbarra said the deal was an "important step" for the UAE, positioning it as "the most important player in artificial intelligence, followed by Saudi Arabia".

Before leaving for the UAE, Trump said in a speech to the U.S. military at the Al Udyid Air Force Base in Qatar, that the defense purchases signed by Qatar on Wednesday were worth $42 billion.

Other deals signed during Trump's four-day swing include a deal by Qatar Airways to purchase up to 210 Boeing's wide, wide-ranging maneuver jets, and a Saudi Arabia pledge to invest $60 billion in the U.S. and purchase $14.2 billion worth of U.S. weapons.

The tour also brought a series of diplomacy, with Trump saying in Qatar on Thursday that the United States is approaching a nuclear deal with Iran. He said on Tuesday that the U.S. will eliminate long-term sanctions on Syria.

Trump said he might return to Washington on Friday, though he said "almost a destination because they'll get a call 'Can you come here? Can you come there?'''

Trump has previously hinted that he could stop negotiating the Russian-Ukrainian war in Istanbul.
