DUBAI, (Reuters) – Iran’s negotiations with six world power aimed at reviving a 2015 nuke deal will resume before the end November. The top nuclear negotiator of Iran stated Wednesday that this was in response to growing Western concerns about the Islamic Republic’s recent nuclear developments.

“Had a very serious & constructive dialogue with @enriquemora_ on the essential elements for successful negotiations. Following a meeting with EU officials in Brussels, Ali Bagheri Kani posted on Twitter: (NYSE:) “We agree to commence negotiations before November.”

He said, “The exact date will be announced during the week to come.”

Six powers and Tehran began to meet in April to talk about salvaging the 2015 nuclear agreement, which was abandoned by Donald Trump three years earlier. Trump placed harsh sanctions again on Iran to ravage its economy, squeezing Iran’s oil exports.

However, the negotiations have been in limbo since June’s election of Iran’s ultra-conservative President Ebrahim Rasi. If the talks resume in Vienna, Raisi is expected to be tough.

Raisi wants to be like Iran’s Supreme leader Ayatollah Al Ali Khamenei and seeks results-oriented discussions that bring Washington and Tehran back in full compliance with the agreement.

Trump’s pressure led Tehran to gradually break the agreement. Tehran rebuilt its stockpiles with enriched Uranium and refined it to a higher fisile purity. Tehran also installed advanced centrifuges to accelerate production.

Since months, the West has urged Iran not to abandon negotiations. However, the time is approaching fast as Tehran’s nuke program moves well past the limit set out in the deal.

Robert Malley (US Special Envoy to Iran) said Monday that the efforts to revive pact are in “critical phases” and Tehran is losing motivation for its refusal of talks.

Six rounds of negotiations in Vienna have concluded, but Washington and Tehran still don’t agree on what steps should be taken. The key questions are what Iran will accept as nuclear limits and Washington’s plans to remove sanctions.

It doesn’t matter to us if America returns to the deal. What is important is that the outcome of talks be in Iran’s favour,” Iranian Foreign Minister Hossein Amirabdollahian said in a televised news conference.

He reiterated Iran’s request for the immediate release of assets that were frozen by U.S. sanctions.

“(U.S. President Joe) Biden has to put his goodwill into practice by for instance releasing $10 billion of Iran’s blocked assets,” Amirabdollahian said.

Due to U.S. bans on Iran’s banking and energy sectors, Iran was unable to access foreign banks holding tens to billions of dollars worth of assets, mostly from oil and gas exports.
