Donald Trump's tariffs on China have significantly impacted global markets. The U.S. has implemented a cumulative tariff rate of 104% on Chinese goods, leading to substantial declines in stock markets worldwide. The S&P 500 fell more than 1.5% following the announcement, while Asian markets also experienced sharp drops, with the Shanghai Composite and Hang Seng indices plummeting by over 8% and 13%, respectively. This move has exacerbated tensions between the U.S. and China, with China vowing to "fight to the end" against what it sees as economic coercion.
