Russia said on Saturday that it wanted written guarantees from the United States that sanctions on Russia would not damage its cooperation with Iran under a 2015 nuclear deal with global powers that Tehran and Washington are seeking to revive.
"We need a guarantee that these sanctions will not in any way touch the regime of trade-economic and investment relations which is laid down in the Joint Comprehensive Plan of Action," Russian Foreign Minister Sergei Lavrov told reporters.
"We have asked for a written guarantee ... that the current process triggered by the United States does not in any way damage our right to free and full trade, economic and investment cooperation and military-technical cooperation with the Islamic Republic."
Russia's demand is "not constructive" for talks between Tehran and global powers to revive a 2015 nuclear deal, a senior Iranian official told Reuters on Saturday.
"Russians had put this demand on table since two days ago. There is an understanding that by changing its position in Vienna talks Russia wants to secure its interests in other places. This move is not constructive for Vienna nuclear talks," said the official in Tehran.
