The IAEA derestricted its quarterly report dated 5 June estimating that as of 20 May “Iran’s total enriched uranium stockpile… was 1571.6kg”, with enrichment rates topping out at 4.5 per cent. Addressing the Agency's board, the U.S. representative maintained: “Iran has continued to expand its proliferation-sensitive activities and is showing no signs of slowing its destablising nuclear escalation... Iran's actions are simply transparent attempts at extortion that seek to intimidate the international community”. She further noted that “we remain ready and willing to negotiate with Iran a comprehensive deal”, adding: “the long-term stability of any diplomatic solution with Iran will require a firm basis in verification”.  Relatedly, in a joint statement, the E3 countries stated that “we are extremely concerned by Iran’s violation of its nuclear commitments, which have grave and irreversible proliferation consequences”. They further reiterated “regret and concern regarding the U.S. withdrawal from the JCPOA including by not extending sanction waivers for nuclear non-proliferation projects”, and affirmed: “we will continue to contribute to the Arak Modernisation Project and support EU-led civil nuclear cooperation projects”.
