North Korean leader Kim Jong Un and Russian President Vladimir Putin exchanged messages reaffirming their deepening bilateral relationship on August 15, Korea's Liberation Day — the 81st anniversary of Japan's 1945 surrender and the end of its 35-year colonial rule of the Korean peninsula. In his reply to Putin's congratulatory message, Kim said he expected a "more excellent future" in ties that had "carried forward the history of common struggle for justice and precious traditions of friendship," and expressed firm belief that Russia would defend its "sovereignty, security interests and territorial integrity" — a formulation widely understood as backing Moscow's war in Ukraine.
Putin, for his part, rooted the relationship in shared wartime history, noting that the bond between the two countries was forged when Soviet soldiers fought against Japan, and said cooperation would continue "in all the sectors." The diplomatic exchange was accompanied by a symbolic gesture: the Russian sailing vessel Pallada docked at Wonsan, a port city on North Korea's eastern coast, for a goodwill visit tied to the anniversary, where it was received by North Korean provincial officials and Russian embassy staff.
The warm signals reflect a relationship that has transformed rapidly in recent years. Since signing a comprehensive strategic partnership in 2024, Pyongyang and Moscow have moved from rhetorical solidarity to active military cooperation, with North Korea deploying troops and weapons in support of Russia's war against Ukraine — its most significant involvement in an armed conflict since the 1950-1953 Korean War. Kim also visited a memorial honouring Soviet soldiers who fought Japan in World War II, marking his third visit to the site on Liberation Day.
The occasion drew starkly different messaging from Seoul. South Korean President Lee Jae Myung used his Liberation Day address to call for dialogue with Pyongyang, urging the two Koreas to work toward replacing their decades-old armistice — which halted but did not formally end the Korean War — with a full "peace regime." Lee said talks could also explore ways to curb North Korea's nuclear programme. Pyongyang has rejected those overtures, denouncing joint US-South Korean military exercises as provocations.
The day also carried broader regional tensions. Earlier in the week, Putin visited one of the Kuril Islands, a chain off Japan's northern island of Hokkaido that the Soviet Union seized in the final days of World War II and over which Japan still claims sovereignty, drawing a sharp condemnation from Tokyo. The overlapping anniversaries and diplomatic manoeuvres underscore how World War II's unresolved legacies continue to shape rivalries and alliances across Northeast Asia.
