The United States and Saudi Arabia have reached a landmark agreement on civilian nuclear energy, the US Department of Energy said, as reported by Reuters.

The agreement allows Saudi Arabia to build nuclear reactors using American technology and to enrich uranium.

The civilian nuclear energy agreement with Saudi Arabia had been in development for years — both during Donald Trump’s first term and under Joe Biden.

However, until now the agreement had not been concluded partly because of warnings that it could open a path for Saudi Arabia to develop nuclear weapons.

Unlike Biden’s plan, the current agreement does not include the so-called Additional Protocol, which allows the UN’s International Atomic Energy Agency to conduct surprise inspections.

The agreement will also allow Saudi Arabia to enrich uranium and reprocess nuclear waste, which is a potential pathway to creating nuclear weapons.

The Department of Energy said the deal is now being sent to Congress. If Congress does not gather enough votes against the deal within 90 working days, it will take effect. But overriding a presidential veto would require a two-thirds majority.
