Should the West Ban Chinese-Made EVs to Protect National Security?

In October 2024, the European Commission officially launched an anti-subsidy investigation into Chinese-made electric vehicles, concluding that China's state aid, including direct subsidies, tax breaks, and cheap credit, has created a 'serious risk' of economic distortion. The probe led to provisional tariffs of up to 38.1% on Chinese EVs, with the Commission stating that Beijing's support has allowed manufacturers to undercut EU rivals by up to 20% on price. This action was justified by both economic and security concerns, as EU officials noted that dependence on Chinese EV technology could create vulnerabilities in critical infrastructure and data flows.

A September 2024 US Department of Commerce report concluded that Chinese-made connected vehicles, including EVs, present an 'unacceptable' risk to national security due to their capacity to collect detailed geolocation, biometric, and driving behavior data on US citizens. The report, which informed a proposed rule to ban Chinese vehicle software and hardware, stated that Chinese manufacturers are subject to Beijing's intelligence law, which compels companies to cooperate with state intelligence activities. It cited examples of Chinese automakers transmitting data to servers in China without clear consent, including video feeds and location trails that could map sensitive sites like military bases and power plants.

A January 2025 independent study by the Technical University of Munich analyzed data transmission from 20 EV models, including Chinese brands BYD, NIO, and MG, alongside Tesla and Volkswagen. The study found that Chinese-made EVs transmitted no more data than their Western counterparts, and all were fully compliant with the EU's General Data Protection Regulation (GDPR). Notably, the researchers found that Tesla's data collection, which sends vehicle and driver data to US servers, was more extensive than any Chinese model tested. The study concluded that 'the security narrative is not supported by technical evidence' and that bans are 'politically motivated rather than data-driven'.

An International Monetary und (IM) working paper from November 2024 modeled the economic impact of Western bans and tariffs on Chinese EVs. The analysis found that a full ban would raise average EV prices in the US and EU by 25-30%, costing consumers an estimated $50 billion per year combined. urthermore, the IM warned that restricting access to affordable Chinese EVs would significantly delay the global transition to zero-emission vehicles, undermining climate goals. The paper noted that China produces 60% of the world's EVs at 30% lower cost than Western equivalents, and that protectionist measures would 'entrench the incumbents' inefficiency' rather than boost innovation, while also harming developing nations that rely on low-cost green tech.
