Iran's Ambassador has poured cold water on hopes of any imminent deal to forcibly send up to 9000 failed Iranian asylum seekers home.

Ahead of a visit by the nation's foreign minister next week, Ambassador Abdolhossein Vahaji told Fairfax Media that Iran had no intention of accepting back its citizens returned forcibly after their asylum applications had been rejected.

His comments follow a report in The West Australian newspaper this week that said talks on the long-running point of contention between the two countries were well-advanced and Foreign Minister Julie Bishop was hopeful of a deal next week.

Asked whether there was any chance of a deal on returning people involuntarily, Mr Vahaji said: "No agreement. No improvement in that regard."
