FNA- Russian Deputy Foreign Minister Sergei Ryabkov voiced his country's regret over the renewal of the Iran Sanctions Act (ISA) and said that Russia assesses the decision as wrong and harmful.

"Russia believes that the political situation was not apt for the US to take such a move," Ryabkov told reporters on Friday.

He reiterated that Russia deems Washington's move as wrong and harmful.

"Moscow was sad that the majority of representatives in the two American legislative bodies voted in favor of renewal of the ISA and believed the votes revealed the general atmosphere prevailing across the US," Ryabkov added.

The senior Russian diplomat said that the US decision was not a correct one, specially given the fact that the first anniversary of the implementation of the Joint Comprehensive Plan of Actions (JCPOA) was imminent.

He said that Russia hoped wiser people would assume positions in the next US Congress.

The senior Russian nuclear negotiator went on to urge all parties to fully abide by the agreement.

He described the JCPOA as a very valuable, useful and a necessary document which has a long-term impact on reinforcement of international security structure.

Both the US House of Representatives and the Senate have voted for the 10-year extension ISA dating back to 1996 in the name of proponent of the bill, the US Senator D'Amato, to penalize the US companies making investments over 20 million dollar worth in the Iranian energy industry.

Renewal of the US sanctions against Iran became law without the US President Barack Obama's signature on Thursday.
