Introduction On April 3, 2025, the U.S. officially implemented a 25% tariff on imported vehicles and auto parts, significantly escalating costs for Japanese and Korean automakers and forcing a restructuring of global supply chains. Meanwhile, emerging markets such as the Middle East and Africa have become critical regions for Chinese new energy vehicle (NEV) manufacturers to fill the gaps left by the retreat of Japanese and South Korean automakers.
