Iranian and American delegations are scheduled to arrive in Muscat on Saturday morning and the negotiations are set to begin in the afternoon, the Revolutionary Guard-affiliated Tasnim News reported.
The talks will begin after separate meetings with Oman's Foreign Minister, who will act as the mediator between the two sides, it added.
The report cited sources familiar with the matter saying Iran has clearly outlined its red lines ahead of the talks. "These include a strict rejection of any threatening rhetoric from the American delegation, a firm refusal to entertain excessive demands or frameworks regarding its nuclear program, and an insistence that no discussions related to Iran’s defense industry be raised."
"Iran will not tolerate any form of threat or attempts to cross these red lines during the negotiations," the report said citing the sources.
"However, they added that Iran remains open to building confidence around the peaceful nature of its nuclear program—provided that sanctions are lifted in return."
"If the US is genuinely concerned only about the possibility of an Iranian nuclear bomb, the path to agreement should not be difficult," Tasnim cited the sources as saying.
"But if the Americans enter the talks with duplicity and excessive demands, they must be prepared to shoulder the international blame for any obstruction of the negotiation process."
