Trump loves cheap oil and high-dollar deals. His trip to Saudi Arabia is putting the two on a collision course.

Oil barely garnered a mention from U.S. President Donald Trump during his glitzy visit to Saudi Arabia this week. But the black gold may explain why the trip went so smoothly.

A Chinese startup has opened the world’s first clinic in Saudi Arabia where artificial intelligence diagnoses patients, a key step in replacing human doctors as the first line of medical treatment.

The deal features a mix of public and private partnerships, a strong emphasis on emerging technologies, and a $142-billion arms deal.

Al-Ittihad, captained by Karim Benzema, clinched the Saudi Pro League title with two matches to spare as they came from a goal down to beat Al-Raed 3-1 on Thursday.

President Trump delivered remarks Tuesday at a U.S.-Saudi investment summit, as he marks his first international trip of his second term.

The meeting came after Trump—who is in the middle of a three-country tour of the Middle East—delivered a speech on Tuesday in which he announced his plan to lift U.S. sanctions on Syria in support of "a new government that will hopefully succeed in stabilizing the country and keeping peace.”

Muhammad bin Salman, the crown prince and de facto ruler, often known as MBS, has been trying for a decade to ease Saudi Arabia’s stultifying social strictures and to reduce the economy’s dependence on oil and the state.
