Iran Suspends Nuclear Talks, Warns It May Block Key Oil Route

Iran halted negotiations with the U.S. on June 1, threatening to close the Strait of Hormuz—a waterway carrying roughly a third of the world's traded oil. The collapse followed months of failed talks over Iran's uranium enrichment and missiles. Tehran's closure threat echoes earlier posturing under sanctions, likely serving as negotiating leverage. Yet Iran simultaneously sent a new proposal through Pakistan, suggesting talks may not be entirely over.
