Iran has received response from the United States on its comments on the European Union;s draft proposal aimed at salvaging the 2015 nuclear deal and lifting draconian US sanctions, the foreign ministry spokesman said on Wednesday.

The spokesman for the Iranian Foreign Ministry says the Islamic Republic has received a response from the United States to the European Union’s proposal on reviving the 2015 nuclear deal, stressing that Tehran will announce its position following thorough assessment of the answer.

Nasser Kan’ani said that Iran had received the US government’s response to its opinions on resolution of the remaining issues in the Vienna negations aimed at the removal of sanctions through the EU coordinator for the talks Enrique Mora on Wednesday evening.

“A careful review of the US opinions has started, and the Islamic Republic of Iran will announce its views in this context after having completed its review,” he added.

On Monday, Kan’ani said Tehran had responded to the EU’s proposal on revival of the 2015 accord, officially known as the Joint Comprehensive Plan of Action (JCPOA), but was awaiting Washington’s response.

“Iran has participated seriously, constructively and responsibly in the negotiations, responded to the proposals of the European side in a timely manner, acted innovatively and showed the necessary flexibility for the conclusion of an agreement,” the Iranian diplomat said during a press conference.

“But what matters now is the procrastination of the American side in providing an answer. The US government is responsible for the JCPOA status quo and non-implementation of the accord. We can move to the next stage in case the US government shows serious willpower and acts responsibly in its promises and actions,” he added.

“We can talk about the success of this phase of negotiations when the European side announces that it has received the response from Americans,” Kan’ani noted.

The United States, under former president Donald Trump, left the JCPOA in 2018 and returned the sanctions that the agreement had lifted.

Iran and the remaining parties to the deal resumed on-and-off talks on a potential revitalization of the deal in the Austrian capital of Vienna since last year, months after Joe Biden succeeded Trump, to examine the potential of the deal’s revival and removal of the sanctions.

Late on August 15, Iran said it had provided the European Union’s coordinator in the JCPOA talks with its final conclusion related to the bloc’s proposals for the revival of the deal, emphasizing that it was now the US’s turn to show realism and flexibility if it really wanted a final agreement to be reached.

The EU confirmed that it had received Iran’s response, saying the bloc was studying the reply with the parties to the deal and the United States.

According to a New York Times report, officials described Iran’s response as “encouraging,” saying it does not raise major new objections.
