Members of the committee, headed by Iranian President Hassan Rouhani, took part in a Wednesday session, during which they described as unjustified the US behavior regarding its commitments under the nuclear deal, known as the Joint Comprehensive Plan of Action (JCPOA).
On December 1, the US Senate voted 99-0 to extend the Iran Sanctions Act (ISA) for a decade after it cleared the House of Representatives 419-1 in late November.
First adopted in 1996 to punish investments in Iran over its nuclear program, the ISA now needs US President Barack Obama’s approval to be turned into law.
Referring to the US Senate vote, the committee members said that the sanctions bill was in blatant violation of the JCPOA.
They also studied retaliatory measures and approved them in case of possible future violations, stressing that the Islamic Republic would closely monitor the US government’s moves and react proportionately.
The committee is expected to hold another meeting next week.
Earlier on Wednesday, Iran’s Ambassador to the United Nations Gholam-Ali Khoshrou submitted an official letter of complaint to UN Secretary General Ban Ki-moon.
Khoshrou wrote that Washington, as a party to the JCPOA, has pledged to neither ratify nor prolong any nuclear-related bans against Tehran.
Iran and the five permanent members of the UN Security Council – the United States, France, Britain, China and Russia – plus Germany started to implement the JCPOA on January 16.
Under the deal, Iran undertook to put limitations on its nuclear program in exchange for the removal of nuclear-related bans imposed against Tehran.
