Grateful to @unodavienna for marking this anniversary with us. Ending nuclear test explosions belongs to the wider non-proliferation and disarmament effort, and our two offices carry that work forward side by side.
30 years ago today, countries began signing the CTBT: no more nuclear weapon test explosions. Anywhere. By anyone. Ever again. 🌍
