President Donald Trump plans to leave Monday for a four-day trip to Saudi Arabia, Qatar and the United Arab Emirates, a mission that is expected to focus heavily on business deals and new investments from the oil-rich region.

The swing through deep-pocketed Middle East monarchies, Trump’s first major international travel of his second term, is a marker of the president’s priorities and another sign of his intention to de-emphasize the traditional U.S. allies that typically serve as the first foreign destinations for new presidents. It also reflects his affection for the region, its wealth, and the pageantry that the host countries plan to roll out for him.
