US President Donald Trump said Saudi Arabia will not enrich uranium under the nuclear cooperation agreement signed this week, and made the deal conditional on Riyadh normalising relations with Israel.

There would be no enrichment of material, Trump said in a Truth Social post on July 23, adding that the agreement was totally subject to Saudi Arabia joining the Abraham Accords. The statement came a day after the deal was formally signed and appeared to introduce a condition not previously disclosed.

US Energy Secretary Chris Wright and Saudi Energy Minister Prince Abdulaziz bin Salman signed the accord on July 22, with the Department of Energy announcing the signature that afternoon. The agreement, concluded under Section 123 of the US Atomic Energy Act, was accompanied by a bilateral safeguards agreement.

The department said the two documents lay the legal foundation for a decades-long, multibillion-dollar partnership advancing economic and strategic objectives including nuclear non-proliferation.

Wright said the agreements reflect a shared commitment to strengthening commercial relations and delivering security to allies abroad. The White House has not published the text.

Reporting before Trump's statement indicated the deal would permit domestic enrichment. CNN, citing two US officials and a source familiar with the matter, reported that the agreement could lead to Saudi Arabia enriching its own fuel for civilian reactors without adopting the gold standard of international oversight, and that the 30-year deal would involve American companies providing technology and expertise.

The network also reported that the agreement includes limits on the inspections that may be carried out on the Saudi programme. A person familiar with the matter said the framework paves the way for a uranium enrichment facility in the kingdom following a joint US-Saudi study.

The deal now goes to Congress for a mandatory review period. Section 123 agreements, which authorise US companies to sell nuclear technology abroad, normally take effect unless veto-proof congressional majorities pass joint resolutions of disapproval.

Senator Ed Markey, a Massachusetts Democrat, said the agreement risked enabling nuclear proliferation in Saudi Arabia and igniting a regional arms race. Henry Sokolski of the Nonproliferation Policy Education Center questioned what precedent the deal would set for the UAE, Turkey and Egypt.

Saudi Arabia has said it will join the Abraham Accords only once an independent Palestinian state exists, making Trump's stated condition difficult to reconcile with Riyadh's declared position.
