Russia had a positive role in the JCPOA and after the US pull-out from the nuclear deal, other sides of the deal should find new mechanisms for its implementation, Ali Larijani said in a meeting with Chairman of the Russian State Duma's Foreign Affairs Leonid Slutsky.
Iran-Russia trade relations are being developed on a daily basis, he added.
Larijani underlined development of the two countries' relations in the banking field.
Elsewhere in his remarks, he referred to Iran-Russia cooperation on Syria, and said that despite the complicated situation, there, the two countries can help resolve the crisis through cooperation.
US President Donald Trump announced on May 8 that Washington would pull out of Iran's nuclear deal and re-impose nuclear sanctions on the country.
This is while most world powers, including Russia, China, and the European Union have repeatedly stressed that keeping the deal is in the interest of the global peace and security.
Earlier, Russia said it sees no room for amendments or additions to the 2015 nuclear deal between Iran and six world countries.
“We are seriously concerned by all of this - I am referring to comments made by the presidents of the United States and France about the Joint Comprehensive Plan of Action (JCPOA) on the Iran nuclear program. Russia has repeatedly said that there is no possibility for some kind of revote for this document, changing or enlarging it,” the spokeswoman for the Russian Foreign Ministry Maria Zakharova said on Thursday.
Elsewhere in her remarks, Zakharova announced an unscheduled meeting of the foreign ministers of Russia, Iran and Turkey in Moscow on April 28, saying the three states – which are cooperating in a peace process on Syria – will exchange views on “including the worsening situation around the implementation of the JCPOA,” among other issues.
