WASHINGTON (AP) — President Donald Trump said Monday he will sell F-35 advanced fighter jets to Saudi Arabia on the eve of Crown Prince Mohammed bin Salman’s Washington visit, as he praised the kingdom for its long partnership with the United States.

“I will say that that we will be doing that,” Trump said when asked if he would sell the jets to Saudi Arabia. “We’ll be selling F-35s.”

The crown prince, who is set to make a White House visit Tuesday, had been expected to arrive with a wish list that includes receiving formal assurances from Trump defining the scope of the U.S. military protection for the kingdom and an agreement to buy U.S.-made F-35 fighter jets, one of the world’s most advanced aircraft.

The Republican administration, however, has been wary about upsetting Israel’s “qualitative military advantage” over its neighbors, especially at a time when Trump is depending on Israeli support for the success of his Gaza peace plan.

Another long-standing concern, which also derailed a potential similar sale to the United Arab Emirates, is that the F-35 technology could be stolen by or somehow transferred to China, which has close ties to both the UAE and Saudi Arabia.
