An official familiar with the negotiations said Iranian negotiators left Doha talks on Sunday, not because of difficulties.

Iranian foreign ministry spokesman BAGHAEI said on Nov. 2 the secretary of Iran’s Supreme National Security Council will decide how and whether to respond to a U.S. letter based on national interest. He said all indirect, mediator-led talks with the U.S. are primarily built on Iran’s "seven-day plan", which has been streamlined and can be fully implemented within two days; its timing flexibility reflects Iran’s goodwill. Implementation of the plan, the start of negotiations and restoration of security in the Strait of Hormuz depend entirely on U.S. decisions, conduct and concrete actions.
