Iran's president warned President Trump on Sunday that pulling the U.S. out of the nuclear deal with world powers would be a "historic regret."
President Hassan Rouhani made the comments in the city of Sabzevar while on a tour of Iran's Razavi Khorasan province.
Rouhani said: "If [the U.S.] opts to pull out of the nuclear deal, it will soon realize that this decision will become a historic regret for them."
Rouhani also assured Iranians that "no change will occur in our lives next week" regardless of Trump's decision.
Trump faces a self-imposed May 12 deadline concerning the 2015 nuclear deal, which he long has criticized.
