In his reply to Putin, Kim Jong-un pledges to expand cooperation with Russia comprehensively; Pyongyang opens its first road link to Russia
In a reply to congratulations on the 78th founding anniversary, published on 15 September, Kim pledged unwavering support for Russia's war in Ukraine. In the same days, North Korea was reported to have opened its first road link to Russia and to be close to completing a bridge on the Chinese border.
According to a Korea Herald report dated 15 September, Kim Jong-un wrote in his reply to Putin's congratulations on the 78th founding anniversary on 9 September that he would expand and deepen joint work with Russia in every field and support Russia's war against Ukraine to the end. In June 2024 the two countries signed a comprehensive strategic partnership agreement providing for military assistance without delay if either party is attacked. Since then Pyongyang has sent thousands of troops and conventional weapons to Russia.
According to an NBC News analysis dated 13 September, North Korea has opened its first road link with Russia. Satellite imagery also shows that the New Yalu River Bridge to China is nearing completion. The regime is trying to balance between Moscow and Beijing as it seeks economic relief. These physical links make sanctions enforcement even harder. The institutionalisation of a channel for exchanging troops, munitions and technology is also changing Seoul's and Tokyo's deterrence calculations on the Korean Peninsula.
Talay assessment
Bottom line
Kim's letter is not a new commitment but a reaffirmation of the June 2024 partnership treaty; the lasting change is that the relationship now has physical infrastructure through the road link and the Yalu bridge. This channel makes sanctions enforcement harder still, and continued flows of troops and munitions to Russia while the war in Ukraine lasts is the most likely path. Pyongyang's balancing between Moscow and Beijing will cap how deep the alliance goes.
Likely effects
- Sanctions regimeNegative1–6 months
Land links open trade and arms-transfer channels that are hard to monitor; the effectiveness of international sanctions on North Korea declines as the exchange of troops, munitions and technology with Russia becomes institutionalised.
- Northeast Asian securityNegative6 months+
A North Korea strengthened by Moscow's backing alters Seoul's and Tokyo's deterrence calculus, increasing pressure on defence spending and alliance coordination with the US.
Possibilities, ranked
- 1Institutionalised military-economic cooperation75%
Road and rail links enter regular use; transfers of troops and munitions continue in return for technology and economic support.
Watch: Reports of regular shipments over the road link and senior military visits between the two countries.
- 2Ukraine ceasefire reduces urgency15%
A halt to fighting in Ukraine lowers Russia's military need for North Korea; the relationship continues mainly on the economic track.
Watch: Concrete progress in Ukraine ceasefire talks and intelligence statements pointing to fewer North Korean troop transfers.
- 3Rebalancing towards Beijing10%
With the New Yalu bridge open, Pyongyang shifts its economic relationship back towards China and visibly limits ties with Moscow.
Watch: The official opening of the New Yalu River Bridge and a senior China–North Korea visit.
