With new weapons, cash and battleground experience from Ukraine, North Korea has become much more formidable

The war between Russia and Ukraine is taking place in Europe, but its security implications are increasingly being felt in Asia, too.

North Korea has benefited tremendously from its decision to supply enormous quantities of ammunition and soldiers to Russia in return for advanced nuclear and missile technology and diplomatic cover.

North Korea's involvement in the conflict is transforming it into a much more capable and technologically advanced rogue state in east Asia. This evolving threat may soon prompt South Korea to reassess its security strategies in an increasingly challenging international environment.

How has North Korea helped Russia?

As Russia's invasion of Ukraine began to turn into a protracted conflict in late 2022, Moscow faced a problem: it was at risk of running low on ammunition and soldiers to send to the front lines.

Its diplomatic overtures to North Korea began soon after.

In July 2023, Russian Defence Minister Sergei Shoigu was warmly received by North Korean leader Kim Jong Un in a visit to the North Korean capital, Pyongyang.
