# Diplomatic dispute over Iran at IAEA conference > Live situation record from CLSTR: https://clstr.news/situations/diplomatic-dispute-over-iran-at-iaea-conference > Updated: 2026-09-14T14:15:32.000Z. Sources: 31. Developments: 2. A diplomatic dispute has emerged at the 70th IAEA General Conference in Vienna following Austria’s decision to deny a visa to Mohammad Eslami, the head of Iran’s Atomic Energy Organization. Austria denied the entry request after a UN sanctions committee waiver was rejected, a move supported by the United States due to concerns over Iran’s production of near weapons-grade uranium and lack of cooperation with inspectors. Iran and Russia have criticized the decision, arguing it violates the IAEA Statute regarding the equal rights of member states. In response to the denial, Iran’s Foreign Ministry summoned Austria’s chargé d’affaires in Tehran to protest what it described as acting under U.S. pressure. The standoff occurs as IAEA Director General Rafael Mariano Grossi warns of global proliferation risks, noting that the agency has been unable to conduct field verification activities in Iran for over six months. Grossi expressed concern regarding the lack of information concerning Iran’s inventory of 60 percent enriched uranium. U.S. Energy Secretary Chris Wright characterized Iran’s lack of transparency as ‘unacceptable.’ ## Timeline ### 2026-09-14: IAEA General Conference opens amid Iran visa dispute The IAEA 70th General Conference opened in Vienna amid disputes over Austria denying a visa to Iran's nuclear chief and warnings from Director General Grossi regarding Iran's nuclear transparency. 3 sources. https://clstr.news/cluster/iaea-general-conference-opens-amid-iran-visa-dispute ### 2026-09-13: Austria denies entry to Iran’s nuclear chief for IAEA conference Austria denied Iranian nuclear chief Mohammad Eslami entry to the IAEA conference in Vienna following a failed UN sanctions waiver request.
