London– Hours after Donald Trump was elected the 45th U.S. president, reactions ranging between fear and anticipation rose in Iran.

Iran’s President Hassan Rouhani said on Wednesday that the U.S. election results would have no effect on Tehran’s policies, noting that Tehran’s expanding economic ties with the world were irreversible.

“The results of the U.S. elections have no effect on the policies of the Islamic Republic of Iran,” Rouhani said.

He added that Iran’s nuclear deal with the six world powers has been reflected in a United Nations Security Council resolution and cannot be dismissed by one government.

The 2015 accord, signed between Iran and six powers, including the U.S., cannot be overturned by one government’s decision.

“Iran’s understanding in the nuclear deal was that the accord was not concluded with one country or government but was approved by a resolution of the U.N. Security Council and there is no possibility that it can be changed by a single government,” Rouhani told his cabinet, according to state television.

Last year’s accord with world powers saw international sanctions on Iran lifted in exchange for guarantees that it would not pursue a nuclear weapons capability.

Rouhani’s statement about the role of the Security Council comes after Iran’s Foreign Minister Mohammed Javad Zarif minimized the role of the U.N. in reaching the agreement, despite the adoption of Resolution 2231.

Rouhani said Trump’s victory won’t be able to stop Iran’s economic growth.

“The constructive engagement policies of Iran towards the world, and the fact that international sanctions have been lifted, have placed the Iranian economy on a road where there is no possibility of going backwards,” Rouhani added.

Trump’s previous statements are expected to affect the course of the presidential elections in Iran happening in May, which Rouhani plans to run for a second term.

Rouhani also questioned the U.S. ability to face Iran, saying: “The United States no longer has the capacity to create Iranophobia and a consensus against Iran.”

Tehran views Trump’s statements as a serious threat to its attempt to succeed in the post-nuclear deal era in which Iran enhances its trust with other nations to establish economic and political relations.

Previously, Trump described the nuclear deal as the worst in the history of America and stressed that canceling the agreement is on his agenda.

Tehran expressed relief at Trump’s program for Syria and Iraq where he called for cooperation with Russia.

Iranian analysts compared between Trump’s focus on fighting ISIS and statements of Democratic candidate Hillary Clinton when she pledged to face Iran’s role in the Middle East and its support for terrorist organizations.
