The White House has said that President Donald Trump would host the United Arab Emirates' Crown Prince Mohammed bin Zayed Al Nahayan, but did not specify a date.
The news comes after Washington said Trump would host Qatar's Emir Tamim bin Hamad Al Thani on April 10 in an effort to end the diplomatic spat.
Bahrain, Egypt, Saudi Arabia and the UAE cut diplomatic and trade ties with Qatar last year, accusing Doha of bankrolling Islamist extremists and fostering ties with Saudi arch-rival Iran.
The White House said Trump spoke on the phone with Prince Mohammed "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.
