Mounting worries regarding reliance on technology are transforming Europe’s strategy for public transit and digital security. A sector that was previously calm and effective in Scandinavia is now the focal point of an intense discussion concerning national defense and digital autonomy.
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 response and data protection assurances
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 scrutiny surrounding Yutong’s buses is only the latest episode in Europe’s complex technological relationship with China. Across the continent, policymakers are attempting to strike a delicate balance between leveraging China’s advanced manufacturing capabilities and protecting national interests. Recent events — including the Netherlands’ decision to seize control of the Chinese-owned chipmaker Nexperia — have fueled concerns that Europe’s automotive and technology sectors could face major disruptions in the event of diplomatic or trade tensions.
Many administrations have already implemented measures to restrict susceptibility to potential weaknesses. Several European countries, emulating the United States, have purged Huawei and ZTE apparatus from their 5G infrastructure, citing espionage and data manipulation hazards. Currently, focus has shifted to the rapidly expanding sector of Chinese electric vehicles. As per JATO Dynamics, Chinese EVs saw their market penetration in Europe double in early 2025, surpassing 5% — a statistic that underscores both consumer demand and regulatory apprehension.
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 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 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.
The intersection of innovation and vulnerability
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 reliance on Chinese-made components and software extends far beyond public transport. From communication networks to renewable energy infrastructure, the continent’s modernization is deeply intertwined with China’s industrial ecosystem. As global tensions rise, the challenge for European nations will be to secure their technological independence without stalling their progress toward sustainability and innovation.
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 the end, as Ken Munro aptly summarized, the debate boils down to one word — trust. And in an increasingly interconnected world, trust may prove to be the most valuable and fragile asset of all.
