- Rafael Grossi said North Korea has made “very serious” progress in its ability to produce more nuclear weapons during a visit to Seoul.
- North Korea is thought to have assembled about 50 nuclear warheads, though some experts doubt its ability to miniaturise them for long‑range ballistic missiles.
- Yongbyon nuclear complex has seen intensified work at its 5 MW reactor, reprocessing unit, light‑water reactor and other facilities, according to Grossi.
- Center for Strategic and International Studies reported satellite imagery shows a new uranium‑enrichment building at Yongbyon nearing operational readiness, and a similar undeclared facility at Kangson.
- Lee Jae Myung warned that North Korea’s production could build 10‑20 nuclear weapons a year and that excess material could be exported, creating a global danger.
- IAEA maintains enhanced readiness to verify North Korea’s nuclear program, calling it a “clear violation” of UN Security Council resolutions.
Why it matters: North Korea’s expanding warhead stockpile and new enrichment facilities boost its nuclear arsenal, breaching UN sanctions and heightening the risk of nuclear material export. This strengthens Pyongyang’s deterrence while eroding diplomatic leverage for the United States, South Korea and the broader international community.
