The leaders of the Middle Eastern countries that President Donald Trump is visiting this week have discovered the keys to the American leader's heart - grand displays and glitzy architecture.

Trump was pumped for the pomp put on display in both Qatar and Saudi Arabia as he leaves for the United Arab Emirates mid-day Thursday.

He was hosted by both leaders in a series of palaces and other grand buildings that met his love of the ostentatious.

On Wednesday night, Qatar's Emir Tamim bin Hamad Al Thani held a state dinner for Trump at the opulent Lusail Palace.

There were camels on hand - and eaten by guests - and Arabian horses leading the Beast, the presidential limo, to the palace's doors.
