"We are prepared for the worst status not only in the political field, but also in the economic field," Takht Ravanchi, a member of Iran's nuclear negotiating team in 2015, said on Tuesday.
He pointed to Iran's commitment to the JCPOA, and said, "Most of the world states want extension of the nuclear deal."
"We will not be the first country which withdraws the JCPOA," Takht Ravanchi, currently Deputy Chief of Staff of Iran's Presidential Office, said, adding that Iran will stay in the nuclear deal as long as it benefits from the deal.
The US administration has done a great deal during the past year to kill the JCPOA. Although the international Atomic Energy Agency has confirmed Iran's commitment to the deal eight times, the US President Donald Trump didn’t confirm Iran's commitment and sent the deal to the Congress to be decided on.
The Congress couldn't reach a decision in the legal period, so the US president is to announce his decision on January 12 on the issue.
