Overview

  • Iran and European E3 envoys met in Istanbul on July 25 to resume talks on Tehran’s nuclear programme after mid-June Israeli-U.S. airstrikes damaged key facilities.
  • Tehran reaffirmed its sovereign right to enrich uranium to 60%, far above the 3.67% cap set by the 2015 accord.
  • France, Germany and the UK cautioned that meaningful concessions are required by autumn or they will invoke the UN snapback mechanism.
  • Iran signalled it will renew cooperation with the IAEA under a “new form,” with inspectors expected to return under revised monitoring terms.
  • Tehran threatened to withdraw from the Nuclear Non-Proliferation Treaty if UN sanctions are reimposed over its enrichment activities.
