A new nuclear agreement with Iran is expected within days, a European diplomat told Fox News on Friday – coming after weeks of renewed talks in Vienna to revive the 2015 Iran nuclear deal.

The diplomat cautioned, however, that any deal involving Iran, China, Russia, and the U.S. could always unravel.

Meanwhile, on Thursday, Iran’s chief negotiator told reporters that a deal would be done within 24-48 hours.
The 2015 Joint Comprehensive Plan of Action (JCPOA) set limits on Iran’s nuclear activity in exchange for a significant rollback of international sanctions. The Trump administration pulled the U.S. out of the deal amid concerns that the agreement did not do enough to curb Iran’s nuclear ambitions -- including the sunset clauses on restrictions.

Iran eventually pulled out of the deal after the Trump administration re-imposed sanctions as part of its maximum pressure campaign, and Tehran has been ramping up its enrichment since then. The International Atomic Energy Agency (IAEA) said this week it believes Iran has significantly increased its stockpile of highly enriched uranium, but that it is unable to verify the exact size of the stockpile due to limits imposed on inspectors by the regime.
