Iran says talks with the United States are unlikely without a "fundamental change" in American behavior.
Foreign Ministry spokesman Bahram Ghasemi told reporters today that any future negotiations were unlikely "considering the policies taken by (President Donald) Trump."
Then-president Barack Obama held a phone call with his Iranian counterpart, Hassan Rouhani, in 2013, the highest level contact since 1979.
US and Iranian diplomats met frequently in the lead-up to the 2015 nuclear accord.
Trump has taken a harder line toward Iran, portraying it as a regional menace.
Ghasemi said that at the UN General Assembly last month, "some people close to Mr Trump requested and expressed his willingness for a meeting with Rouhani." He said Rouhani declined.
The White House said reports that Trump requested a meeting were false.
