It is the latest message of support from Pyongyang to Moscow since the beginning of the war in Ukraine, which it has described as a US “proxy war” to destroy Russia.
As a permanent member of the UN Security Council, Russia has long held the line against increasing pressure on North Korea, which is under wide-ranging UN and Western sanctions over its nuclear weapons and missile programmes.
Leif-Eric Easley, a professor at Ewha University in Seoul, said Russian President Vladimir Putin’s invasion of Ukraine threatens the “stability of the Russian state”.
“There will be implications for the Russia-China-North Korea bloc, and officials in Beijing and Pyongyang are no doubt taking notes to avoid repeating Moscow’s mistakes,” he added.
