Iran says talks format changed after US ‘threatening statement’ Iran's foreign ministry spokesperson Esmaeil Baghaei said the Iranian delegation refused to continue quadrilateral talks involving the United States, Pakistan and Qatar in Switzerland after what he described as a "threatening statement" by US President Donald Trump during the negotiations. Speaking to Iranian media, Baghaei said Qatar and Pakistan attempted to keep the four-party format in place, but Tehran rejected the proposal. "Qatar and Pakistan tried to continue the talks, and we said it would not be a quadrilateral meeting," he said.
