Vladimir Putin has accepted Kim Jong Un’s invitation to visit North Korea, according to the country’s state news agency.
While there was no immediate confirmation from Moscow, KCNA reports the Russian president will visit “at a convenient time”.
Kim is currently in Russia, where he has vowed to support the Kremlin’s “sacred war” against Ukraine, raising concerns the two nations could bolster their military capabilities.

“At the end of the reception, Kim Jong Un courteously invited Putin to visit the DPRK at a convenient time,” KCNA reports, referring to the Democratic People’s Republic of Korea, the country’s formal name.
“Putin accepted the invitation with pleasure and reaffirmed his will to invariably carry forward the history and tradition of the Russia-DPRK friendship.”
The two leaders toasted their friendship on Wednesday with Russian wine after Mr Putin showed Kim around the country’s most modern space launch facility.
They also held talks alongside their defence ministers and called each other “comrades”.
The burgeoning friendship has concerned the West, with Washington accusing North Korea of providing weapons to Russia.
It is not clear if any deliveries have been made and the two states have denied those claims in any case – but they did promise to deepen defence cooperation.
Kim is due on Thursday to visit military and civilian aviation factories in the Russian city of Komsomolsk-on-Amur and to inspect Russia’s Pacific fleet in Vladivostok, Mr Putin said.
What kind of weapons could North Korea provide?
Aidan Foster-Carter, a researcher in sociology and modern Korea at Leeds University, told Sky News North Korea can probably supply “good quality ammunitions” to Russia.

Sky’s Diana Magnay has analysed what help North Korean might be able to offer Putin in the war against Ukraine.
He said Mr Putin and Kim each had something the other wanted – but it was still unclear exactly what that was going to be.
Russia needs artillery shells, he said, and he is “betting” Kim needed money, food and cheap oil.
Asked how Kim could help Mr Putin, he said North Korea was a “highly-militarised state” and focused on producing armour.
“They probably can supply good quality ammunitions,” he said.
