Iran's supreme leader said on Tuesday that his country's future should not be tied to the success or collapse of nuclear talks with world powers, Iranian state media reported, adding that the negotiations to revive a 2015 nuclear deal "are going well", News.az reports citing Mehr.

Ayatollah Ali Khamenei, who has the last say on all state matters such as Iran's nuclear programme, made the comments about a month after almost a year of indirect talks between Iran and the United States stalled. Both countries blame each other for lack of "political will" to settle remaining issues.

"Absolutely do not wait for nuclear negotiations in planning for the country and move forward," Khamenei told a gathering of senior officials, state TV reported.

"Do not let your work be disrupted whether the negotiations reach positive or semi-positive or negative results."
