Whatever practical cooperation emerges from this week’s summit between Russian President Vladimir Putin and North Korean leader Kim Jong Un, their deepening relationship is aimed at sending their rivals a warning, analysts said.

Calling each other “comrade”, the men toasted their friendship on Wednesday after Putin showed Kim around Russia’s most modern space launch facility and they held talks alongside their defence ministers.

The two countries have an interest in demonstrating that, despite their geopolitical isolation, they have partners they can call on. And both seek to weaken US-led sanctions and pressure campaigns, against Russia over the war in Ukraine and against North Korea for its nuclear weapons and missile programs, analysts said.

“Putin and Kim would both gain from a transactional bargain but they would also gain geopolitically by giving off the impression that their nuclear-armed countries are cooperating militarily and sending a warning about potential consequences to America’s allies and like-minded partners that support Ukraine,” said Duyeon Kim, of the Center for a New American Security.

“Kim would also be signalling to Washington, Seoul and Tokyo that Russia has his back in Northeast Asia.”

Both Russia and North Korea have denied US claims that they plan to provide each other with weapons, but the leaders promised to deepen defence cooperation, and Putin said Russia would help the North build satellites.

If they simply wanted a secret arms deal, the two leaders did not have to meet in person, said Leif-Eric Easley, a professor at Ewha University in Seoul.

“Putin and Kim’s diplomatic display is meant to claim success in challenging the US-led international order, avoiding over-reliance on China, and increasing pressure on rivals in Ukraine and South Korea,” he said.

Discussions of any open violation of UN Security Council resolutions on North Korea would signal that major international agencies will be paralysed, said Andrei Lankov, a Korea expert at Seoul’s Kookmin University.

The summit is an indicator that North Korea-related Security Council resolutions are dead, as are all attempts to stop North Korea or penalise it for having a nuclear program, he said.

“It creates an important precedent that is likely to be used not only by Russia but pretty much every major international player that if you don’t like a UNSC resolution you just ignore it,” Lankov said.
