Chinese EV manufacturers, including BYD and GAC Aion, are expanding into Southeast Asia but face significant challenges such as inadequate infrastructure, stiff competition, and consumer skepticism. In Vietnam, BYD struggles against local leader VinFast, which sold 87,000 of 91,500 EVs last year, partly due to limited charging stations for Chinese brands. To enhance their market presence, Chinese firms are investing in local production, exemplified by BYD's $1.3 billion factory in Indonesia, while experts emphasize the need for better charging networks and a deeper understanding of local consumer preferences.
