Saudi Crown Prince Mohammed bin Salman met Tesla CEO Elon Musk, who was introduced by US President Donald Trump during talks at al-Yamamah Palace on Tuesday.

The Crown Prince also met with Sam Altman, CEO of OpenAI.

Trump arrived in Riyadh on Tuesday morning for what he described as a “historic visit” and the first stop in a four-day sweep through the Gulf region.

After Trump assumed his second term in January, his first phone call with a foreign leader was with Saudi Crown Prince Mohammed bin Salman—a move that US circles described as a strong message to a key partner and long-standing friend of 80 years.

Alongside the historic political ties between the two countries, Trump is keen on maintaining a close relationship with the Saudi Crown Prince, as evidenced by various occasions and statements. In an exclusive interview with Al Arabiya, Trump described the Crown Prince as a "great man with a great vision."

The close ties between Washington and Riyadh extend to many fields and have an international impact. This was reaffirmed by Crown Prince Mohammed bin Salman during his meeting with US Secretary of State Marco Rubio in Riyadh, where he reiterated his welcome to working with Trump and his administration in a way that serves the interests of Saudi Arabia, the United States, and many other countries.
