Iran formally offered to suspend uranium enrichment for five years during Islamabad negotiations with US officials including Vice President JD Vance. The Trump administration rejected the proposal, demanding a twenty-year freeze instead. The two sides also disagreed on Iran's enriched uranium stockpile. The US wants it removed entirely; Iran proposed diluting it. Russia offered to accept the uranium as a compromise. Vance said progress was made but Iran "didn't move far enough." A US naval blockade of Iranian ports took effect Monday.
