Pyongyang shows no signs of denuclearisation as it prepares for Xi visit.

North Korea (the DPRK) has a nuclear arsenal of 60 warheads, a think tank has claimed.

The Stockholm International Peace Research Institute (SIPRI) estimates that as of last January, the DPRK

had probably assembled around 60 warheads and possessed enough fissile material to potentially produce at least 90 warheads.

The same research—published on Sunday, June 7th, in the SIPR 2026 yearbook—contrasts with previous years’ estimates, which described North Korea as possessing 50 assembled warheads.

Last week DPRK leader Kim Jong Un inspected his country’s third and newest (known) site for enriching fuel for producing nuclear materials, as he prepared to meet Chinese leader Xi Jinping in Pyongyang on Monday, June 8th, for their first summit since September.
