In the wake of the nuclear agreement with Iran, President Barack Obama will meet Friday with Saudi Arabia’s foreign minister, a White House official said.

It is Obama’s first meeting with a key American ally from an Arab state since reaching the Iran deal, The Wall Street Journal reported on Friday.

Saudi Arabia is the largest of the Arab states that have been deeply skeptical of Obama’s diplomatic outreach to Iran.

Obama’s meeting with Saudi Foreign Minister Adel al-Jubeir comes as the White House is working to ease fears among Arab states and follow through on commitments made earlier this year to provide them with new military and security guarantees.
