Speaking at a meeting with Russia’s State Duma Speaker Vyacheslav Volodin on Friday, Larijani said that Iran has borne huge costs to achieve the agreement and he expects that Moscow will contribute to settling the issues around the deal.
"If they [US] act like it then there will be hardly anything left from this agreement. So a new issue will arise on the international arena," he said at a meeting with Volodin.
Larijani pointed out that Tehran will respond to US' possible withdrawal from the agreement.
The speech comes after the Washington Post reported on that Trump intended to "decertify" the nuclear deal with Iran. Under the terms of the current nuclear agreement, Trump has until October 15 to certify Iran's compliance.
The nuclear deal, that was agreed upon by Tehran and the so-called P5+1 group (China, France, Russia, the United Kingdom, United States plus Germany), stipulates the lifting of anti-Iranian sanctions in exchange for Tehran ceasing the production of nuclear weapons. It was signed in July 2016.
