Vice President JD Vance said negotiations between Washington and Tehran have achieved "great progress," despite periods of tension and sharp exchanges during talks in Bürgenstock, Switzerland.
According to Vance, the talks continued successfully despite what he characterized as "threatening" and "whining" during the negotiations.
The discussions faced strain over the weekend after Iran announced the closure of the Strait of Hormuz in response to Israeli military strikes in Lebanon, arguing that the attacks violated an existing ceasefire arrangement.
Vance said both sides are also working to establish a regional "deconfliction mechanism" aimed at preventing future crises from escalating into wider conflict.
Earlier, Iranian Foreign Minister Abbas Araghchi likewise described the latest round of talks as having produced "major progress," reported by officials involved in the negotiations.
