Iran's foreign minister Hossein Amirabdollahian arrived in Moscow on Tuesday and expressed hopes his visit would lead to Russian support for a "good, stable and strong nuclear deal," Iran's semi-official ISNA news agency reported.
Amirabdollahian said Russia had so far supported talks in Vienna to revive a 2015 nuclear deal between Iran and major powers.
The talks are at risk of collapsing after a last-minute Russian demand forced world powers to pause negotiations for an undetermined time, despite having a largely completed text.
