The Guardian view on Putin and Kim: an alarming new pact needs close attention | Editorial

The revival of ties between Russia and North Korea is prompted by events outside Asia, but the best hopes of containment may lie within the region

A shiny, sanctions-busting Russian limousine for KimJong-un. A fawning, rapturous reception for Vladimir Putin. These grand gestures may be welcomed by the North Korean and Russian leaders, but are intended as much for their global audience as for each other. The real prize is the strategic partnership treaty that they signed during Mr Putin's first visit to Pyongyang since 2000. The question is what it will mean in practical terms.

The relationship has been reinvigorated by events outside Asia, but hopes of containing it lie within the region. The proximate cause is evidently Russia's invasion of Ukraine: an isolated and impoverished Pyongyang is already believed to have supplied millions of artillery shells in return for cheap oil, food and other sorely needed goods. Russia might also benefit from North Korean manpower, though much more likely for labour than combat.
