The US government is stepping up efforts to regulate Chinese technology in connected vehicles over national security concerns. In response, South Korea and other key allies are collaborating to balance security interests with potential disruptions to the supply chain. A meeting convened by the US State Department brought together representatives from allied governments and industry leaders to explore ways to safeguard critical infrastructure without stifling innovation, particularly in the context of connected vehicles which play a crucial role in the broader network of personal devices and telecommunications systems. The primary concern is the potential for cyberattacks facilitated by the integration of Chinese technology, prompting an ongoing investigation by the US Commerce Department and the possibility of future restrictions on connected vehicles utilizing Chinese components. South Korea's automotive industry, which relies on certain Chinese components, is particularly apprehensive about the impact of potential regulations. Korean government and industry officials have requested a grace period to assess the specific measures' impact on supply chain disruptions, particularly as the broad definition of "connected vehicles" could potentially encompass numerous China-sourced components used in Korean vehicles. Although no specific measures were discussed during the meeting, a tentative bill is expected to be unveiled in September. In summary, the US government's focus on regulating Chinese technology in connected vehicles has prompted collaboration among key allies, including South Korea, to address security concerns while mitigating supply chain disruptions. The potential impact on Korean vehicles, which rely on Chinese components, has raised apprehension, prompting requests for a grace period to evaluate the measures' impact. The meeting did not yield specific measures, but a bill is anticipated to be revealed in September.
