This year’s Hiroshima Round Table was held on July 12-13 as a hybrid event, with Japanese experts attending in person and international participants by Zoom.

It took place against a threefold backdrop. The postponed 50th anniversary tenth review conference of the Nuclear Nonproliferation Treaty will be held in New York next month. The roundtable unanimously affirmed the importance of the NPT as the cornerstone of the global nonproliferation regime.

The other global nuclear normative framework is the Treaty on the Prohibition of Nuclear Weapons which bans the bomb. It entered into force in January 2021 and the first meeting of states parties was held in Vienna on June 21-23. All 86 signatories are also NPT non-nuclear weapon states parties.
