U.S., Iran Negotiations Threatened by Dispute Over Billions in Frozen Tehran Funds

A major dispute is emerging between the US and Iran over billions of dollars in potentially unfrozen Tehran funds, threatening to undermine a landmark Iran deal brokered by former President Donald Trump. The issue stems from a 2016 UN Security Council resolution that calls for the return of frozen Iranian assets. A regional analyst has warned that this dispute could test the durability of the US-Iran agreement, which aims to limit Iran's nuclear program in exchange for relief from economic sanctions.
