U.S. Secretary of State Marco Rubio acknowledged he faces a delicate mission this week pitching Washington’s Iran peace deal to Gulf Arab leaders who fear excessive concessions will strengthen Tehran and reshape the region’s security ‌balance and oil flows.

America’s top diplomat arrived in the United Arab Emirates late on Tuesday and was due to travel in coming days to Kuwait and Bahrain, where he will meet officials from the Gulf Cooperation Council, a grouping of monarchies that also includes Saudi ⁠Arabia, Qatar and Oman.

Asked if he was planning to address allies’ disquiet with the accord, Rubio told reporters: “That most certainly will come up in these discussions.” He said they would also discuss issues not covered by the memorandum of understanding.

The House approved the resolution earlier this month.
