Specific details were not given but earlier media reports , externalsuggested that, after undertaking a joint study with the US, Saudi Arabia may be allowed to enrich uranium on its soil to produce fuel at a US-built enrichment facility, instead of relying on imported fuel.

This could be worth billions of dollars to the US, whose companies could be involved in building a facility to produce enriched uranium, which can be used as fuel for power plants but also to make nuclear bombs.

According to Wednesday’s statement, the deal will “advance US and regional security by upholding high standards of nuclear safety, security, and nonproliferation and strengthening the United States’ competitive edge in civil nuclear technology”.

“Rest assured, these agreements uphold the highest standards of nuclear safety and nonproliferation, while relying on the world’s best nuclear technology and scientists, designed right here in the United States,” said US Secretary of Energy Chris Wright.

“Thanks to President Trump, the American nuclear renaissance is underway and will deliver long-term benefits to the American and Saudi people.”

Nuclear experts and former officials in Israel – the US’s top ally in the Middle East – voiced concern the plan could ultimately lead to Saudi Arabia being able to develop a nuclear weapon.

The agreement will now be sent to Congress for review. Some lawmakers on both sides of the political aisle are also expected to oppose the deal, though Trump’s Republican Party controls both the upper and lower chambers.
