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 transport providers in Denmark and Norway are facing a possible security vulnerability within their electric bus fleets, particularly in vehicles manufactured by Yutong, the globe’s leading bus producer headquartered in Zhengzhou, China. The problem arises from the buses’ capacity to accept remote software updates and perform diagnostic assessments – a functionality that, despite its technological sophistication, also sparks worries that the vehicles could be disabled or controlled remotely.
Movia, the premier public transportation authority in Denmark, has conceded that this wireless capability could enable an external entity—be it the producer or a cybercriminal—to remotely incapacitate a bus. Jeppe Gaard, Movia’s chief operating officer, clarified that this issue isn’t exclusive to Chinese manufacturers but represents a wider concern linked to the growing digital integration in contemporary vehicles. Both electric cars and buses, he pointed out, are heavily dependent on networked systems that are, theoretically, susceptible to remote access and deactivation.
Since 2019, Movia has incorporated more than 260 Yutong buses into its fleet serving Copenhagen and eastern Denmark. Similar concerns were echoed in Norway, where Ruter, a major public transportation provider, conducted its own investigation. The company carried out controlled tests on both Yutong and Dutch-made VDL buses in secure, underground facilities. The findings showed that while the Dutch models lacked remote update capabilities, Yutong maintained direct digital access to its vehicles for software updates and diagnostics — meaning that, at least theoretically, the buses could be rendered inoperable remotely, even though they could not be remotely driven.
China’s reaction and data security guarantees
Yutong has responded to these claims by affirming its compliance with international regulations and emphasizing its commitment to data privacy and cybersecurity. The company stated that all vehicle data within the European Union is securely housed in an Amazon Web Services data center located in Frankfurt, Germany. Yutong further assured that all stored information is encrypted, protected by strict access controls, and inaccessible without explicit customer authorization.
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 wider European predicament
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 concerns
Security specialists throughout Europe, however, maintain a degree of skepticism. Richard Dearlove, the former head of MI6, cautioned that Western administrations are confronting a predicament akin to the one presented by Huawei during the deployment of 5G technology. From his perspective, the growing ubiquity of internet-connected automobiles produced by Chinese companies might introduce novel points of weakness. He posited that, under the most dire circumstances, China could hypothetically incapacitate numerous electric vehicle fleets in prominent urban centers — a situation capable of paralyzing transit systems during an emergency.
Still, some cybersecurity experts contend that such a situation, though technically possible, is improbable. Ken Munro, the creator of the Anglo-American company Pen Test Partners, pointed out that any vehicle connected to the internet—regardless of whether it’s manufactured by a Western or Chinese firm—inherently carries dangers of distant manipulation. Even prominent names such as Tesla, he clarified, rely on software connections that could be compromised under particular circumstances.
In light of these worries, Ruter has put in place several safeguards, such as improved cybersecurity measures, firewalls, and more rigorous scrutiny of upcoming vehicle purchases. The organization is also collaborating with national agencies to define more precise cybersecurity guidelines for public transportation networks. Nevertheless, specialists are still split on the adequacy of these preventative steps. Munro warned that the sole guaranteed way to eradicate the danger would be to entirely disconnect vehicles from the internet — an action that would simultaneously impede the capacity to carry out essential updates and remote upkeep.
The intersection of innovation and vulnerability
The debate unfolding in Scandinavia underscores a broader paradox of the digital age: the same technologies that enable efficiency and innovation can also expose systems to new forms of risk. As cities strive to modernize public transport and reduce carbon emissions through electrification, they must also grapple with questions of technological sovereignty, data privacy, and national security.
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.
