Overview

• Britain, France and Germany formally activated the JCPOA snapback on Aug. 28, opening a 30‑day window that could reimpose UN measures by Sept. 28.
• China and Russia joined Iran in a joint foreign-ministers’ letter calling the European snapback attempt legally and procedurally flawed, according to Reuters.
• Tehran disputes the E3’s authority, says it will respond if sanctions return, rejects talks under coercion, and claims at least 15 outreach messages to Washington received no reply.
• Iran is enriching uranium to about 60% and has curtailed routine IAEA cooperation since July after strikes on nuclear sites, a gap the E3 cited in pressing for restored verification.
• An adviser to President Masoud Pezeshkian warned renewed UN sanctions would severely strain Iran’s economy and international ties, while Iranian officials welcomed Russia‑China proposals for more time through a short technical extension.
