Iran's top negotiator said Tehran will return to talks in hopes of reviving the abandoned 2015 nuclear deal.

In 2018 under former President Donald Trump, the US backed out of the deal and reimposed sanctions, which hit significant portions of the Iranian economy, including much of its shipping industry.

Bagheri Kani tweeted following meetings with European Union officials on Wednesday that talks would resume by the end of November.

"Exact date would be announced in the course of the next week," Kani said.
