Saudi foreign ministry said it highly commends mediation efforts by Pakistan and Qatar.

U.S. Vice President Vance said the agreement grants the U.S. authority to take action against Iran's nuclear program.

U.S. Republican Senator Lindsey Graham, an ally of Trump, said he welcomed Iran's agreement to a memorandum of understanding on reopening the Strait of Hormuz but warned Tehran's interpretation appears to differ from that of the U.S. negotiating team. He said he will monitor talks on Iran's nuclear program and other issues, and noted that under U.S. law any nuclear agreement with Iran must be submitted to Congress for review and a vote. He expects to review the final draft and said Vice President Vance and the negotiating team should be involved in submitting the accord to Congress.
