Iranian Foreign Minister Abbas Araqchi said on November 16 that there remains a "limited opportunity" for nuclear negotiations with the West, according to Iranian state media.
Relations between Tehran and the United States have been especially tense since then-President Donald Trump withdrew unilaterally from a 2015 nuclear deal with Iran and global powers and reimposed tough U.S. sanctions on Iran.
"There is still an opportunity for diplomacy, although this opportunity is not much. It is a limited opportunity," Araqchi was quoted as telling state television.
Western concerns at Iranian actions have soared amid the yearlong war in the Gaza Strip after U.S.- and EU-designated terrorist organization Hamas carried out a brutal attack in Israel in October 2023, with Iranian allies including Huthis in Yemen and Hezbollah in Lebanon attacking Israel in support of Hamas.
With Trump poised to return to the White House in January following his election victory earlier this month, reports circulated of possible informal contacts, including claims that Trump ally Elon Musk met last week in New York with Iran's envoy to the United Nations.
After days of silence, Tehran on November 16 "categorically denied" that any such meeting took place.
This week, Rafael Grossi, head of the UN's International Atomic Energy Agency (IAEA), urged Iran and its global partners to achieve "concrete, tangible, and visible results" in talks over Tehran's nuclear program as the return of Trump could mean the window for diplomacy is closing.
The 2015 deal, known officially as the Joint Comprehensive Plan of Action (JCPOA), had given Iran some limited relief from international sanctions in exchange for curbs on its nuclear program designed to prevent it from acquiring a nuclear weapon.
After Washington's withdrawal from the JCPOA, Iran expanded its nuclear program and restricted IAEA inspections of its nuclear sites.
U.S. President Joe Biden entered the White House in 2017 pledging to try to revive the deal but made no breakthroughs.
Trump's announced pick for secretary of state, U.S. Senator Marco Rubio, is generally regarded as an advocate of tough action to counter Iranian influence through a return to a "maximum pressure" policy.
