TEHRAN, April 21 (Xinhua) -- Iran's economy would not be negatively affected by the possible withdrawal of the U.S. from the 2015 international nuclear deal, Iran's President Hassan Rouhani said Saturday.

Iran is prepared for the U.S. president's possible decision to pull out of the nuclear deal internationally known as Joint Comprehensive Plan of Action, Rouhani said.

The recent reforms that the Iranian administration made to the currency market was a preemptive measure before the U.S. likely decision against Iran, he was quoted as saying by Tasnim news agency.

Besides, the Atomic Energy Organization of Iran has developed technical plans to surprise the United States in case it scraps the deal, he said at a meeting of governmental officials.

Last week, Iran's Central Bank (CBI) banned non-governmental forex market from buying, selling and transferring foreign currencies in an attempt to regulate and stabilize currency rates.

The new move by the Iranian government comes as the forex market in Iran went out of control and the value of local currency rial plunged sharply over the past weeks.

U.S. President Donald Trump has repeatedly lashed out at the nuclear pact and demanded the elimination of sunset clauses for some of the restrictions the U.S. places on Iran from the nuclear deal.

He also called for stronger inspection rules and limitation to Iran's development of long-range missiles.

But Iran says it will neither tolerate anything beyond its commitment to the nuclear deal, nor accept changes to the agreement.

Iran has threatened to withdraw from the deal if it cannot receive economic benefits.
