The United States on Tuesday signed a wide-ranging set of agreements with Saudi Arabia covering civil nuclear cooperation, artificial intelligence, and a major defence package that includes long-awaited F-35 fighter jets, the White House announced.

In its statement, the White House said Washington and Riyadh had finalised a Joint Declaration on the Completion of Negotiations on Civil Nuclear Energy Cooperation, establishing a legal framework for a “decades-long, multi-billion-dollar partnership built on strong non-proliferation standards.”

The administration also confirmed that President Donald Trump approved a “major defence sale package” involving future deliveries of advanced F-35 aircraft. According to a detailed factsheet on the White House website, the new agreements deepen the US–Saudi strategic partnership, expand opportunities for American workers, and reinforce regional security.

The deals follow Crown Prince Mohammed bin Salman’s visit to the United States, during which Saudi Arabia increased its investment commitments in the US from the $600 billion pledged during Trump’s visit to Riyadh in May to nearly $1 trillion.

The factsheet said the latest agreements cover several sectors: a Civil Nuclear Cooperation Agreement; a critical-minerals framework aimed at diversifying supply chains; and an artificial intelligence memorandum of understanding that grants Saudi Arabia access to American AI systems while safeguarding US technology. The two nations also signed a Strategic Defence Agreement, described by the White House as strengthening their more than 80-year-long security partnership and enhancing deterrence across the Middle East.

The defence package includes future F-35 jets and nearly 300 American-made tanks, which the White House said will bolster the US industrial base and support high-paying American jobs.
