The United States has recently implemented extensive tariff policies, attracting global attention. On April 2, President Trump signed an executive order imposing a uniform tariff of 10% on nearly all imported goods and raising higher tariffs on imports from China and 57 other countries. China strongly opposed this, announcing an 84% tariff on all American imports. These measures caused turmoil in global markets, with the S&P 500 index dropping over 15%. Subsequently, Trump announced a 90-day suspension of tariffs for most countries, but raised tariffs on China to 125%. This move prompted mixed reactions in Congress, with Republicans welcoming it and Democrats criticizing the erratic nature of the policies. The market reacted positively to this, with the S&P 500 index rising by 5.6%. However, experts warned that ongoing trade tensions could lead to a global economic recession. #美国加征关税
