A new road bridge linking Russia and North Korea has been delayed despite nearing completion, with analysts suggesting the crossing could significantly deepen bilateral cooperation. While Moscow and Pyongyang present the project as a boost to trade and tourism, investigations and monitoring reports have prompted renewed scrutiny over its potential military significance as the two countries continue to strengthen ties following Russia’s war in Ukraine.
Russia and North Korea are nearing completion of their first direct road connection, a bridge spanning the Tumen River that will link the Russian town of Khasan with the North Korean town of Tumangang. Originally scheduled to open on 19 June to coincide with the second anniversary of the strategic partnership agreement signed by Russian President Vladimir Putin and North Korean leader Kim Jong-un, the project has been postponed because of delays on the Russian side of the border.
According to several analyses based on satellite imagery, construction of the Russian border facilities has fallen behind schedule, preventing the bridge from becoming operational as planned. Although neither government has announced a revised opening date, the crossing is expected to facilitate the movement of goods and people between the neighbouring allies, whose political, economic and military cooperation has expanded since the beginning of the war in Ukraine.
The bridge is situated in a remote frontier region close to the point where Russia, North Korea and China meet. Satellite images taken on 25 June and analysed by 38 North, an organisation affiliated with the US-based Stimson Center research institute, indicate that North Korea has completed the external construction of its customs warehouse, access roads, checkpoint and a large parking area.
Progress has been markedly slower on the Russian side. The border complex, projected to be at least three times larger than its North Korean counterpart, remains under construction, with little visible advancement at the customs entry point or sections of the connecting road network. Based on these observations, 38 North considers it unlikely that the crossing will become operational in the immediate future.
The entire transport complex stretches 4.7 kilometres, including the approach roads, while the bridge itself extends for approximately one kilometre. It consists of two traffic lanes, each six metres wide. Russia is also constructing a customs checkpoint with ten inspection lanes designed to process up to 300 vehicles and 2,850 people each day.
Russian and North Korean authorities have described the bridge as an investment in trade and tourism, arguing that it will reduce transportation costs and shorten the route between Vladivostok and Rason, the North Korean special economic zone that includes Tumangang, by around 320 kilometres.
However, an investigation by the Ukrainian human rights organisation Truth Hounds, reported by The Guardian, questions whether those economic justifications alone explain a project that was estimated to cost around 9 billion rubles, more than €100 million, when budgeted. The latest available estimate from the Russian Association of Exporters and Importers valued bilateral trade between the two countries at just $34 million, or approximately €30 million, in 2024.
Truth Hounds also casts doubt on tourism as a sufficient rationale for the investment. North Korea remains largely closed to foreign visitors, permitting only organised groups from Russia under tightly controlled itineraries accompanied by official guides. Russian border statistics recorded just 5,075 tourist visits by Russian citizens to North Korea in 2025, while organised tours from China, which accounted for more than 90 per cent of foreign visitors before the pandemic, have yet to resume.
Instead, the organisation argues that the bridge’s principal value may be strategic. According to its assessment, the road connection could serve as a logistical corridor that is less vulnerable to Western surveillance, allowing the movement of soldiers, construction personnel and military equipment into Russia, while facilitating the transfer of technology and supplies in the opposite direction. Compared with rail transport, trucks are considered more difficult to monitor because they can be loaded and unloaded more quickly and operate across a wider road network.
The new crossing lies approximately 500 metres south of the Friendship Bridge, opened in 1959, which has until now served as the only land connection between the two countries. Railway traffic across that bridge between Khasan and Tumangang has long been monitored by researchers using satellite imagery to identify possible arms trafficking routes.
Those observations showed a significant increase in traffic after Putin and Kim accelerated their rapprochement in 2023. According to the Multilateral Sanctions Monitoring Team (MSMT), North Korea has since supplied Russia with more than 20,000 containers of ammunition and military equipment. In 2024 alone, those deliveries may have included up to nine million artillery shells and rockets, together with at least 100 ballistic missiles.
While initial shipments reportedly travelled by rail before maritime transport became the principal route, the MSMT says missiles, launchers and other sensitive military equipment have continued to move mainly by train or military aircraft. The independent body, comprising 11 countries including South Korea, Japan, the United States, France and the United Kingdom, monitors potential violations of United Nations Security Council sanctions imposed on Pyongyang.
Military cooperation has also expanded beyond equipment transfers. Both governments confirmed in 2025 that North Korean troops had been deployed to Russia. It is estimated that around 14,000 North Korean soldiers were sent to Russia’s Kursk region during the autumn of 2024 after Ukrainian forces occupied part of the territory. South Korean intelligence estimates that approximately 2,000 North Korean soldiers were killed in combat.
Ukrainian President Volodymyr Zelensky warned on Saturday that Russia was preparing to receive a further 30,000 North Korean troops, claiming accommodation facilities had been under construction since June in Russia’s Voronezh region. He also alleged that Pyongyang intended to deliver additional ballistic missile launchers to Moscow, stating that Russia was helping North Korea improve its weapons, acquire combat experience and refine its military capabilities. The Kremlin declined to comment on Zelensky’s claims.
The MSMT further maintains that Russia has supplied North Korea with air defence systems, advanced electronic warfare equipment and refined oil in quantities exceeding United Nations limits. According to findings from the Truth Hounds investigation reported by The Guardian, the new bridge would provide a faster, more flexible and less easily monitored route, potentially further strengthening cooperation between the two countries.
