Iran warned yesterday that it could "seriously reconsider" its obligations to the International Atomic Energy Agency (IAEA) if European signatories to the nuclear deal resort to a mechanism to resolve disputes that could lead to sanctions.

The nuclear deal signed in Vienna in 2015 is in danger of collapsing since the United States unilaterally withdrew from it last year and began imposing sanctions on Tehran, while the three European signatories Britain, France and Germany are trying to save it, but so far their efforts have not been successful. .

"If they launch the mechanism, Iran will be forced to seriously reconsider its obligations to the IAEA," said Iranian Parliament Speaker Ali Larijani.

"If they think this will benefit them more, they can move forward," he told a news conference in Tehran.

A year after Washington pulled out of the deal, Tehran began to take a series of steps that violate its obligations under the agreement, and after its latest action this month to backtrack on its commitments, warned European countries that they would resort to the dispute settlement mechanism in the agreement.

"The impasse with the United States will be resolved if Washington learns from the past," he said, noting that before the nuclear deal was signed in 2015, then US President Barack Obama wrote a letter, saying he "agrees to enrich uranium for Iran, and now let's negotiate."

"If US officials take advantage of the experience of the past, they will be able to resolve this issue," Larijani said.

On the other hand, Israel condemned the accession of six new European countries to the mechanism «Instex» trade exchange with Iran, saying it encourages Tehran to suppress protests at home.

The Paris-based INCASTS mechanism is supposed to act as a clearing house to allow Iran to continue selling oil in return for importing other products or services necessary for its economy, but the process has not yet been conducted.
