The White House said Trump spoke on the phone with bin Zayed, his country's de facto ruler, "to discuss regional developments and opportunities for increasing cooperation on a range of security and economic issues."
A statement added: "The leaders agreed that all GCC (Gulf Cooperation Council) states can and should do more to increase coordination with each other and with the United States to ensure the peace and prosperity of the people in the region."

It said the pair "agreed on the importance of a united GCC," in what appeared to be a reference to the regional dispute, since the GCC member countries are Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and the UAE.
