TEHRAN (Press Shia Agency) – Iran’s Foreign Ministry spokesman on Monday warned against implementation of a US congressional bill extending anti-Tehran sanctions, which will violate the JCPOA, unveiling plans for of a package of measures by Iran in retaliation to such a move.

Iran will not renege on its commitments to the Joint Comprehensive Plan of Action (JCPOA) as long as the other parties do not violate the deal, Bahram Qassemi said at a weekly press conference in Tehran, in reaction to the US congressional decision to extend the Iran Sanctions Act (ISA) for ten more years.

He also reminded the US not to swim against the current, because the JCPOA is not a bilateral agreement, but a multilateral deal between Iran and the Group 5+1 (Russia, China, the US, Britain, France and Germany).

The spokesman made it clear that Iran has made preparations for reaction to  any breach of the JCPOA by the US or any other party, saying Tehran has plans for every scenario.

“Our reaction in the first stage will be a political and legal move, and if we fail to reach a certain solution to the US breaches, we will press on with our measures in various fields according to a package we have,” Qassemi added.

His comments came after the US Senate voted 99-0 to extend the ISA for another decade. The bill was passed by the House of Representatives nearly unanimously in November, and congressional aides said they expected President Barack Obama would sign it.

On Sunday, Iranian President Hassan Rouhani said implementation of the bill will draw a decisive response from Tehran, noting that even Obama’s endorsement of the bill will provoke Iran’s commensurate reaction.
