Saudi King Salman bin Abdulaziz has decided not to attend a summit of Gulf leaders which is hosted by the US President Barack Obama, and sending his Crown Prince to represent him, Saudi Arabia's Foreign Minister, Adel al Jubeir said in a statement on Sunday.
Al Jubeir said the Crown Prince Mohammed bin Nayef have been assigned to lead the Saudi delegation during the summit which will be held on May 14, at Camp David.
The Deputy Crown Prince Mohammed bin Salman and a group of senior officials will also accompany with bin Nayef.
The king decided to stay in the country and focus on the Yemen cease-fire and humanitarian aid effort according to al Jubeir.
Arab Gulf allies are expecting the US would defend them against increasing threat of ISIS as situation in Syria and Iraq and the conflict in Yemen continues to destabilize the region.
It is also expected that Obama would try to reassure the allies over Iranian nuclear deal.
Yousef Al Qtaiba, the United Arab Emirates' ambassador to the United States said they were looking for reassurance, given the behavior of Iran in the region and also against the militant groups.
"In the past, we have survived with a gentleman's agreement with the United States about security,” said al Qtaiba.
“I think today, we need something in writing. We need something institutionalized."
With the previous King Abdullah died on January 23, 2015 , his brother Salman became the king.
Salman replaced the Crown Prince Muqrin bin Abdulaziz with the Deputy Crown Prince Mohammed bin Nayef bin Salman with a surprise decision in late April .
He also appointed his son, Prince Mohammed bin Salman, as deputy crown prince, and replaced veteran Foreign Minister Prince Saud al Faisal with the kingdom's Washington ambassador Adel al-Jubeir.
