President Donald Trump made the announcement as he wrapped his Gulf tour of Saudi Arabia, Qatar and the UAE, with a pledge by oil power Abu Dhabi - the UAE's capital and richest emirate - to hike the value of its energy investments in the US to $US440 billion ($A685 billion) in the next decade.
He pledged on Thursday to strengthen US ties with the UAE, announcing deals totalling over $US200 billion, including a $US14.5 billion commitment from Etihad Airways to invest in 28 American-made Boeing aircraft.
"We work together and the money that's made here comes back to us," Trump told Abu Dhabi Crown Prince Sheikh Khaled bin Mohamed bin Zayed during a news conference in Abu Dhabi on Friday, touting the business relationship between the US and UAE.
"We've made it work, and you know they were being wooed by others. But there's no more wooing, I think we're in pretty good shape," he said.
"Absolutely," the crown prince said.
The AI deal, finalised on Thursday, is a boost for the UAE, which has been trying to balance its relations with its longtime ally the US and its largest trading partner China.
It reflects the Trump administration's confidence that the chips can be managed securely, in part by requiring data centres be managed by US companies.
"Yesterday the two countries also agreed to create a path for UAE to buy some of the world's most advanced AI semiconductors from American companies, a very big contract," Trump said.
The UAE energy investment commitment was announced during a presentation by Sultan Al Jaber, Abu Dhabi state energy giant ADNOC's chief executive, to Trump during the last stage of his tour that has drawn huge financial commitments from the UAE, Saudi Arabia and Qatar.
The enterprise value of UAE investments in the US energy sector would be boosted to $US440 billion by 2035 from $US70 billion now, Al Jaber told Trump, adding US energy firms will also invest in the UAE.
Already in March, when senior UAE officials met Trump, the UAE had committed to a 10-year, $US1.4 trillion investment framework in the US in sectors including energy, AI and manufacturing to deepen reciprocal ties.
"We're making great progress for the $US1.4 (trillion) that UAE has announced it intends to spend in the United States," Trump said on his last stop on a Gulf tour that has focused, at least publicly, on investment deals, not security crises in the Middle East, including Israel's war in Gaza.
However, Trump did engage in some diplomacy on his whirlwind meetings with some of the world's biggest energy producers.
He met with Syria's new interim President Ahmed al-Sharaa in Riyadh and said he would order the lifting of sanctions on Syria at the behest of Saudi Arabia's crown prince, a major US policy shift.
