President Donald Trump pulled the United States out of the agreement during his first term in 2018.Since then, there have been stop-and-start talks between Iran and Western powers to revive the deal, but negotiations have stalled.
Iran suspended its cooperation with the International Atomic Energy Agency (IAEA) after the United States and Israel bombed Iran's nuclear facilities in June.
In August, Britain, France and Germany jointly notified the UN Security Council that Iran was in significant violation of the nuclear deal, triggering the reinstatement of suspended international sanctions.
The three European powers announced last week they would resume discussions aimed at finding a "comprehensive, durable and verifiable agreement."
However, Iranian Foreign Minister Abbas Araghchi said Tehran does "not see any reason to negotiate" with the Europeans, given they triggered the snapback mechanism.
