Iran’s deputy foreign minister says changes to a U.S. visa waiver program that now impose travel restrictions on those who visit Iran contradict the landmark nuclear agreement between Tehran and world powers.

The U.S. recently tightened security requirements of its visa waiver program, which allows citizens of 38 countries to travel to the U.S. without visas.

Now, people from those countries who have traveled to Iran, Iraq, Syria and Sudan in the past five years must obtain visas to enter the U.S.

Deputy Foreign Minister Abbas Araghchi told state TV late Sunday that the nuclear deal bars policies intended to adversely affect normalization of trade and economic relations with Iran.

Araghchi said the new visa requirement would negatively affect economic, cultural, scientific and tourism relations with Iran.
