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.

Indirect talks between Iran and the US in Vienna have been on hold since the summer, when the two sides took a break for Iranian elections.

The two sides, using the remaining signatories as intermediaries, had hoped to revive a deal that saw sanctions on Iran lifted in exchange for the country agreeing to limit its nuclear programme.

Reportedly, current President Joe Biden would like to see the deal revived and will hold meetings with the UK, Germany and France on the issue later this week.

All three countries are signatories to the agreement, alongside Russia and China.

Despite the stringent US sanctions, Iran continues to export oil, using a host of tactics including automatic identification manipulation and so-called identity theft, where a ship takes on a false International Maritime Organization-registered profile, to avoid sanctions.

The tactics have created issues for shipping companies around compliance, with some complaining identity theft is impossible to detect unless they are provided with direct evidence.

The sanctions have also been blamed for holding up the tanker market recovery.

Rates for crude tankers have rallied in recent weeks, with the Baltic Dirty Tanker Index hitting 796 on Wednesday after starting the month at 630, but remain at depressed levels.

The sanctions are said to keep older tonnage on the water with shipowners unfazed by the possibility of being frozen out of US financial markets fixing ships to carry sanctioned cargoes.

Lifted sanctions, they say, would send those ships to the scrapyard while increasing the supply of oil, which recently eclipsed $80 a barrel on both the West Texas Intermediate and Brent Crude benchmarks.
