A senior U.S. official said the prisoner swap deal with Iran would not change "the nature of hostility between Washington and Tehran."
Iran remains an adversary, but the door remains open to diplomacy over Iran's nuclear program, he said.
In the same context, Washington imposed sanctions on the Iranian Ministry of Intelligence and former President Ahmadinejad, as the website of the US Treasury Department showed that the United States imposed sanctions on those mentioned on Monday.
The deal is a separate track
US Secretary of State Antony Blinken commented at a press conference in New York on the prisoner swap deal with Iran.
"This path that led to the release of those Americans who were detained was separate from the nuclear program and Iran's behavior," Blinken told reporters.
"We are focused on working to bring American citizens back to their families."
"The matter (the exchange deal) is not reflected in the relationship, and we will continue our determination to take appropriate steps to deal with Iran's actions in many areas," he said.
"The first issue with Iran is the nuclear program, and diplomacy is the best way to reach a tangible and sustainable outcome."
"At the moment we are not communicating with Iran but we will see if there are opportunities in the future, but Biden has been clear that he is committed that Iran will not get a nuclear weapon."
"I wouldn't expect anything this week. We focused on the fact that these Americans are free after their suffering. Some have spent eight years in an unjust prison."
