U.S. Pres­i­dent Don­ald Trump kicked off a four-day Mid­dle East trip on Tues­day in Sau­di Ara­bia, putting the fo­cus on seal­ing eco­nom­ic agree­ments with a key Mideast al­ly while shared con­cerns about Iran’s nu­clear pro­gram and the war in Gaza bub­ble in the back­ground.

Crown Prince Mo­hammed bin Salman, the Sau­di de fac­to ruler, warm­ly greet­ed Trump as he stepped off Air Force One at King Khalid In­ter­na­tion­al Air­port in the Sau­di cap­i­tal. The two lead­ers then re­treat­ed to a grand hall at the Riyadh air­port, where Trump and his aides were served tra­di­tion­al Ara­bic cof­fee by wait­ing at­ten­dants wear­ing cer­e­mo­ni­al gun belts.

“I re­al­ly be­lieve we like each oth­er a lot,” Trump said lat­er dur­ing a brief ap­pear­ance with the crown prince at the start of a bi­lat­er­al meet­ing.
