North Korea’s powerful politburo discusses follow-up steps to Kim’s Russia visit.

During the first official gathering of the powerful politburo of the ruling Workers’ Party since his return, North Korean leader Kim Jong Un reviewed follow-up actions to his recent trip to Russia, according to state media KCNA on Friday.

Kim and Russian President Vladimir Putin agreed to increase their military and economic cooperation during Kim’s recent week-long trip to Russia, which ended with his return.

The influential politburo of the party central committee, which Kim informed on his visit on Wednesday, discussed methods to “practically and comprehensively” execute the outcomes of the meeting as well as “constructive” long-term strategies for improving ties with Russia, according to KCNA.

He emphasized the need to foster close ties and collaboration between the two nations’ relevant sectors to broaden and advance cooperation in all areas in an all-around fashion, the statement read.

According to KCNA, Kim’s visit “brought a radical change in the global geopolitical situation” and elevated bilateral relations to a new strategic level in response to the demands of the new era.

Seoul and Washington are concerned that Russia may be attempting to obtain ammunition from North Korea to augment its dwindling stockpiles due to the conflict in Ukraine. At the same time, Pyongyang is looking for technical assistance for its nuclear and missile programs.

In a speech to the annual U.N. General Assembly on Wednesday, South Korean President Yoon Suk Yeol said that if Russia assisted North Korea in developing its weapons programs in exchange for assistance with its conflict in Ukraine, it would be “a direct provocation,” and Seoul and its allies would not be silent.
