Iran on Monday cited "good progress" in talks aimed at reviving the 2015 nuclear agreement with the West.

- So far, we had good progress - Foreign Ministry spokesman Nasser Kanaani told reporters in Tehran.

Agreement on all issues

- But negotiations are a totality and there should be agreement on all issues. As long as there is no (overall) agreement, we cannot say we have reached a deal…although remaining issues in terms of percentage (of all issues) are small, but they are important - he added.

The spokesman said the Americans have not replied to Iran’s latest response to the latest European Union proposal for a nuclear agreement.

- We can speak about whether the negotiations were fruitful once the European Union announces it has received a response from the Americans. So far, this has not happened - Kanaani added.

"Maximum pressure campaign"

The Iranian spokesman insisted that the Europeans and Americans need to reach a nuclear deal more than Tehran.

Former US President Donald Trump unilaterally withdrew the US from the Iran nuclear deal in 2018 and reimposed sanctions as part of a "maximum pressure campaign" on Tehran.

Iran retaliated by stepping back from its nuclear-related commitments under the deal. Tehran has since exceeded thresholds on the enrichment of uranium, as well as the amount it is allowed to possess under the pact.
