Growing concerns about technological dependence are reshaping Europe’s approach to public transportation and cybersecurity. What was once a quiet and efficient sector in Scandinavia is now at the center of a heated debate about national security and digital sovereignty.
Rising alarms over Chinese-built buses
Public transportation operators in Denmark and Norway are confronting a potential security flaw in their electric bus fleets, specifically in vehicles produced by Yutong, the world’s largest bus manufacturer based in Zhengzhou, China. The issue stems from the buses’ ability to receive remote software updates and diagnostic checks — a feature that, while technologically advanced, also raises concerns that the vehicles could be immobilized or manipulated from afar.
Movia, Denmark’s leading public transit agency, has acknowledged that this over-the-air functionality could allow a third party — either the manufacturer or a hacker — to remotely disable a bus. Jeppe Gaard, Movia’s chief operating officer, explained that the problem is not unique to Chinese manufacturers but is a broader challenge tied to the increasing digitalization of modern vehicles. Electric cars and buses alike, he noted, rely heavily on online systems that can, in principle, be accessed and deactivated remotely.
Since 2019, Movia has integrated over 260 Yutong buses into its operational fleet for Copenhagen and eastern Denmark. Comparable worries were voiced in Norway, where Ruter, a prominent public transport operator, conducted an independent inquiry. The firm executed controlled evaluations of both Yutong and Dutch-manufactured VDL buses within protected, subterranean facilities. The results indicated that while the Dutch models lacked the functionality for remote updates, Yutong retained direct digital connectivity to its vehicles for software enhancements and diagnostics — implying that, at least hypothetically, the buses could be disabled remotely, despite not being capable of remote driving.
China’s reaction and data security guarantees
Yutong has addressed these allegations by asserting its adherence to global standards and underscoring its dedication to data protection and digital security. The company declared that all vehicle-related data within the European Union is safely stored in an Amazon Web Services data facility situated in Frankfurt, Germany. Yutong additionally guaranteed that all retained information is encrypted, safeguarded by stringent access limitations, and cannot be accessed without explicit customer consent.
Despite these reassurances, European authorities and transit companies remain cautious. The incident has intensified discussions about Europe’s growing dependency on Chinese technology — a relationship characterized by mutual economic benefits but shadowed by deep geopolitical mistrust. Beijing’s alleged involvement in cyber espionage, intellectual property theft, and surveillance activities has led many European leaders to reconsider the long-term implications of their reliance on Chinese suppliers for critical infrastructure.
A broader European dilemma
The examination of Yutong’s buses represents just one recent chapter in Europe’s intricate technological ties with China. Throughout the continent, political leaders are striving to achieve a careful equilibrium: harnessing China’s sophisticated production prowess while simultaneously safeguarding national interests. Recent occurrences, such as the Netherlands’ move to take over the Chinese-owned chip manufacturer Nexperia, have intensified worries that Europe’s automotive and tech industries might encounter significant disturbances should diplomatic or commercial disputes arise.
Many governments have already taken steps to limit exposure to potential vulnerabilities. Several European nations, following the example of the United States, have removed Huawei and ZTE equipment from their 5G networks, citing risks of espionage and data manipulation. Now, attention has shifted to the rapidly growing market for Chinese electric vehicles. According to consultancy JATO Dynamics, Chinese EVs doubled their market share in Europe in early 2025, reaching over 5% — a figure that highlights both consumer interest and regulatory unease.
China, for its part, has dismissed Western fears as unfounded and politically motivated. Earlier this year, a spokesperson for China’s Foreign Ministry criticized U.S. restrictions on Chinese automotive technology, arguing that such measures “overstretch the concept of national security.” Chinese officials maintain that their companies operate transparently and pose no threat to foreign nations.
Western Intelligence Worries
Security experts across Europe, however, remain skeptical. Former MI6 chief Richard Dearlove warned that Western governments are facing a challenge similar to the one posed by Huawei during the 5G rollout. In his view, the increasing prevalence of connected vehicles built by Chinese manufacturers could create new vulnerabilities. He suggested that, in a worst-case scenario, China could theoretically disable fleets of electric vehicles in major cities — a scenario that could disrupt transportation networks during a crisis.
Still, some cybersecurity professionals argue that such a scenario, while technically feasible, is unlikely. Ken Munro, founder of the British-American firm Pen Test Partners, noted that any internet-connected vehicle — whether produced by a Western or Chinese company — carries inherent risks of remote interference. Even well-known brands like Tesla, he explained, depend on software connectivity that could be exploited under specific conditions.
In response to these concerns, Ruter has implemented a series of protective measures, including enhanced cybersecurity protocols, firewalls, and stricter oversight of future vehicle acquisitions. The company is also working with national authorities to establish clearer cybersecurity standards for public transport systems. However, experts remain divided on whether such precautions are sufficient. Munro cautioned that the only foolproof method to eliminate the risk would be to completely remove online connectivity from vehicles — a move that would also hinder the ability to perform critical updates and maintenance remotely.
Where groundbreaking ideas meet susceptibility
The discussion emerging in Scandinavia highlights a wider contradiction of the digital era: the very technologies that facilitate efficiency and progress can simultaneously expose systems to novel types of hazards. As urban centers endeavor to update public transit and decrease carbon output via electrification, they are also compelled to confront issues concerning technological autonomy, information confidentiality, and national defense.
Europe’s dependence on Chinese-manufactured parts and programs reaches well beyond its public transportation systems. From its communication grids to its green energy facilities, the continent’s advancement is profoundly linked to China’s industrial framework. As international conflicts escalate, the task for European countries will involve safeguarding their technological autonomy while continuing their journey towards ecological balance and pioneering development.
The debate over Yutong’s bus fleet highlights a critical point: cybersecurity is now as vital as sustainable power in defining the trajectory of city transportation. This challenge extends beyond a single nation or producer, marking a pivotal moment for the subsequent stage of Europe’s digital evolution.
In conclusion, as Ken Munro so aptly put it, the core of the discussion centers on a single concept—trust. And in our progressively intertwined global landscape, trust could very well emerge as the most precious and delicate commodity.
