US President Donald Trump has announced deals totalling over $200 billion between the United States and the United Arab Emirates, including a $14.5 billion commitment between Boeing, GE Aerospace and Etihad Airways, the White House says.

UAE President Mohammed bin Zayed Al Nahyan also presented Trump with the Order of Zayed, the UAE's highest civil decoration and credited Trump with building the two nations' economic partnership to new heights.

The White House said Boeing and GE had received a commitment from Etihad Airways to invest $14.5 billion to buy 28 American-made Boeing 787 and 777X aircraft powered by GE engines. Etihad did not immediately respond to a request for comment. GE and Boeing did not comment.

"With the inclusion of the next-generation 777X in its fleet plan, the investment deepens the longstanding commercial aviation partnership between the UAE and the United States, fuelling American manufacturing, driving exports," the White House said.

Trump pledged to strengthen US ties to the Gulf State as he announced the deals.

"I have absolutely no doubt that the relationship will only get bigger and better," he said.

Etihad has a fleet of around 100 aircraft.

Etihad CEO Antonoaldo Neves said last month that Etihad planned to add 20 to 22 new planes this year, as it aims to expand its fleet to more than 170 planes by 2030 and boost Abu Dhabi's economic diversification strategy.

Etihad, which is owned by Abu Dhabi's $225 billion wealth fund ADQ, has been through a multi-year restructuring and management shake-up, but has expanded under Neves.

He said that 10 of the new aircraft this year would be Airbus A321LRs, which the carrier launched on Monday and will start operating in August. The remainder include six Airbus A350s and four Boeing 787s.

The announcement comes as US sought to block arms sales to the UAE over its alleged involvement in Sudan's civil war and concern about crypto currency ties.

Democrats Chris Murphy, Chris Van Hollen, Brian Schatz and Tim Kaine and Bernie Sanders, an independent who caucuses with Democrats, introduced resolutions of disapproval in the Senate that would block three arms sales to the UAE.

The senators cited concerns that have been raised about Abu Dhabi arming Rapid Support Forces (RSF) paramilitaries in Sudan's civil war. The UAE has repeatedly denied such charges.

They also cited the announcement by MGX, an investment firm backed by the Emiratis, that it would use a stablecoin launched by Trump's World Liberty Financial crypto venture for its $2 billion investment in crypto exchange Binance.

"The Trump administration's end-run around Congress is irresponsible and will further embolden the UAE to violate the UN's Darfur arms embargo and continue its support for the RSF and the killing of innocent civilians," Meeks and Jacobs said in a statement.
