Recently, the United States announced a new round of high tariffs on Chinese electric vehicles, lithium batteries, steel, and aluminum products, drawing significant global market attention. This move may not only further exacerbate the trade tensions between China and the United States but also bring uncertainty impacts on the global supply chain. For exporting companies, cost pressures may rise, and consumers may also face price increases. In the context of a still fragile global economic recovery, will such trade barriers trigger a new round of competition? This is worth our continued attention and reflection.
