“We have warned our Western partners against taking such a step by reminding them of the negative implications of such a process,” the Islamic Republic News Agency (IRNA) quoted Mikhail Ulyanov as saying on Saturday.
“The Kremlin views this measure taken by the three European states in negative light,” he added.
Last week, the three European signatories to the Joint Comprehensive Plan of Action (JCPOA) released a statement saying the mechanism was activated in response to what they claimed was Iran’s repeated violations of the accord.
Iran, however, has rejected the accusations, saying it has suspended its JCPOA obligations as permitted under the deal in cases where other JCPOA signatories fail to uphold their commitments.
The European push to trigger the dispute mechanism may ultimately lead to the restoration of UN sanctions against Iran which were lifted under the JCPOA.
In a press conference on Friday, Acting Russian Foreign Minister Sergei Lavrov slammed the European measure as a “dangerous turn” which aims to use the moment of heightened tensions between Iran and the US to “blame Iran for all what happened”.
He said the European signatories of the deal had failed to set up a promised trade mechanism to bypass US sanctions against Iran and uphold their JCPOA commitments.
Washington imposed crippling economic sanctions against Iran after unilaterally pulling out of the nuclear deal in May 2018.
The US has since coupled economic measures with regional military deployments and provocations as part of a bid to wage a campaign of “maximum pressure” against Tehran.
Earlier this month, Washington ignited serious tensions in the region by assassinating Lieutenant General Qassem Soleimani in Baghdad International Airport while he was on a formal visit to Iraq.
Iran retaliated by firing volleys of ballistic missiles at Ain al-Asad, a large airbase hosting about 1,500 US troops in Western Iraq, and another outpost in Erbil, the capital of the semi-autonomous Iraqi Kurdistan, last week.
