TEHRAN, Aug. 11 (Xinhua) -- Iranian experts started reviewing the proposals from the European Union (EU) to revive the 2015 Iran nuclear deal after the Iranian delegation returned from Vienna, Iran's Noor News website reported on Thursday.

"No high-level meeting has yet been held to review the ideas of the European Union coordinator in Tehran," said the report, adding that the preliminary result of the expert-level review will be presented to relevant decision-making institutions for a final decision.

The EU on Monday put forward a final text of the draft decision on reviving the nuclear deal, while awaiting political decisions from participants of the Vienna talks.

The talks on reviving the Iranian 2015 nuclear deal, formally known as the Joint Comprehensive Plan of Action (JCPOA), began in April 2021 in Vienna but were suspended in March because of political differences between Tehran and Washington.

The latest round of talks, which had begun on Thursday following a five-month hiatus, came to an end on Monday.

Iran signed the JCPOA with world powers in July 2015, agreeing to curb its nuclear program in return for the removal of sanctions on the country. However, former U.S. President Donald Trump pulled Washington out of the agreement and reimposed unilateral sanctions on Tehran, prompting the latter to drop some of its commitments under the pact.
