North Korean leader Kim Jong-un sends a congratulatory letter to Russian President Vladimir Putin ahead of Russia’s National Day, North Korea’s state media reports. The North’s Korea Central News Agency (KCNA) says the message expresses Kim’s “warmest congratulations” and reaffirms ties with Moscow. The correspondence is conveyed through North Korea’s ambassador to Russia, Sin Hong Chol, and is reported without additional details beyond the formal diplomatic delivery.

Multiple reports describe the letters as part of a broader pattern of close North Korea–Russia engagement since the two leaders signed a “comprehensive strategic partnership” in June 2024. That treaty is widely characterized as reviving or deepening Cold War-era-style military and strategic cooperation. Following the June 2024 summit, reports say North Korea deploys around 15,000 combat troops to support Russia in its war against Ukraine and expands cooperation on several fronts.

KCNA also previously reported Kim sending a congratulatory message to Putin for Russia’s Victory Day celebration. Taken together, the new letter presents continued North Korea support for Russia’s policies and positioning ahead of Russia’s holiday.
