North Korean leader Kim Jong Un sent a letter to Russian President Vladimir Putin on August 15, 2026, expressing pride in the deepening ties between the two countries and thanking Putin for his congratulatory message on the 81st anniversary of Korea's liberation from Japanese colonial rule [1, 2, 3]. Kim said, "I am always proud to be able to expect more excellent future of the bilateral relations by leading, together with you, the DPRK-Russia ties that has carried forward the history of common struggle" [4].

Putin’s message emphasized the historic bond forged when Soviet soldiers fought Japan and stressed continued cooperation "in all the sectors" between the two nations. He said, "Our states are actively cooperating in all the sectors while making concerted efforts to ensure the regional security and stability" and called the partnership "unprecedentedly high" [2, 3, 4].

Kim reaffirmed his "firm belief that under your wise leadership, Russia will prosper and successfully defend its territorial integrity," highlighting Pyongyang’s alignment with Moscow's strategic goals [1, 4].

The exchanges came amid evidence of North Korea's growing military support for Russia since Russia's full-scale invasion of Ukraine in 2022. Analysts say Pyongyang has provided troops and weapons, marking its most significant military involvement abroad since the 1950s conflict [2, 5, 6]. Ukraine accused Russia of launching ballistic missile attacks using North Korean-made missiles, which killed at least nine people and injured dozens, and Kyiv claimed up to 50,000 North Korean soldiers might be deployed in Russia, though no proof or timeline has been provided [5, 6, 7]. Some sources do not reference troop deployment numbers, reflecting uncertainty in the reporting [1, 2].

In return, North Korea reportedly received military technology and economic assistance from Russia, strengthening bilateral cooperation [6, 4].

On August 15, the Russian ship Pallada arrived at Wonsan port in North Korea for a goodwill visit related to the Liberation Day celebrations. It was greeted by North Korean officials and the Russian embassy staff [2, 3, 4].

Meanwhile, South Korean President Lee Jae Myung called for talks with North Korea to replace the Korean War armistice with a formal peace regime and to curb Pyongyang's nuclear program. Pyongyang rejected the overtures and criticized the US-South Korean military exercises. Lee said, "The two Koreas need safeguards to prevent conflict and should work to replace their armistice with a peace regime" [2, 3].

Separately, Putin visited a disputed island near Hokkaido, Japan, seized by Russia after Japan’s 1945 surrender, drawing condemnation from Tokyo in August 2026 [2, 3].

The next key diplomatic moment will come with ongoing discussions around the Korean Peninsula’s security and Russia-North Korea cooperation, especially as South Korea pushes for talks on denuclearization and peace in the region.
