Kremlin expressed concern about Iran's decision to resume uranium enrichment, President Vladimir Putin's spokesman Dmitry Peskov said on Tuesday.
"The dismantling of the Joint Comprehensive Plan of Action [JCPOA] does not bode well," he said.
Peskov said they understand Iran’s concerns over the unprecedented sanctions against the country, which are deemed illegal.
Russia supports keeping the Iran nuclear accord, also known as the JCPOA, which was signed in 2015 between Iran and Russia, China, France, the U.K. and the U.S. plus Germany.
"We are watching the developments with concern because it is not good to destroy a comprehensive plan," Peskov stated.
Earlier on Tuesday, President Hassan Rouhani said Iran would begin the fourth step in decreasing its commitments to the nuclear agreement.
Tensions have been escalating between the U.S. and Iran after President Donald Trump withdrew the U.S. in May 2018 from a nuclear pact struck between Tehran and the five permanent members of the UN Security Council plus Germany and the EU.
Following the U.S.' unilateral decision to withdraw from the agreement, Iran started to cut its commitments to the deal in a retaliatory move.
The U.S. has since embarked upon a diplomatic and economic campaign to ramp up pressure on Iran to force it to renegotiate the agreement.
The deal allows Iran to reduce its commitments in the event of a breach from other parties. Tehran insists the EU take more active steps to implement its obligations, and said it would return to full compliance with the deal once the EU has nullified U.S. sanctions.
