DUBAI (Reuters) - Iran said on Tuesday that talks with world powers over reviving its 2015 nuclear deal would resume in a few weeks, the official Iranian news agency IRNA reported.

"Every meeting requires prior coordination and the preparation of an agenda. As previously emphasised, the Vienna talks will resume soon and over the next few weeks," Iranian Foreign Ministry spokesman Saeed Khatibzadeh said, according to IRNA.

The world powers held six rounds of indirect talks between the United States and Iran in Vienna to try and work out how both can return to compliance with the nuclear pact, which was abandoned by former U.S. President Donald Trump in 2018.

The Vienna talks were adjourned in June after hardliner Ebrahim Raisi was elected Iran's president and took office in August.

Ministers from Britain, China, France, Germany and Russia will not meet jointly with Iran at the United Nations this week to discuss a return to the talks, European Union foreign policy chief Josep Borrell told reporters on Monday. 

But Khatibzadeh said Iranian Foreign Minister Hossein Amirabdollahian would meet individually with ministers from those countries on the sidelines of the annual U.N. gathering of world leaders and the nuclear deal and the Vienna talks would be among the main topics under discussion, IRNA reported.
