This systematic review, following PRISMA guidelines, examines China's strategic leadership in electromobility and its implications for global sustainability. China is the undisputed global epicenter, accounting for nearly 60% of global electric vehicle sales in 2023, supported by the world's largest charging network and absolute control over the supply chain. This dominance is built on a decades-long state strategy encompassing three critical dimensions: securing critical minerals (controlling over 75% of lithium refining and 70% of rare earths); mastering battery production (with CATL and BYD controlling over 70% of global cell manufacturing); and deploying massive charging infrastructure that doubles as a geopolitical tool through initiatives like the "Electric Silk Road." The strategy extends to public transport, where 98% of the world's electric buses operate in China, and has driven global battery costs down by 89% since 2010. The article concludes that China has transformed electromobility from an environmental initiative into a comprehensive strategy for global leadership. By demonstrating that sustainability and industrial power are inextricably linked, the Chinese model proves that a state-led green transition is both technically feasible and economically transformative, positioning sustainable mobility as a tool for mitigating climate change while projecting geopolitical influence.
