U.S. President Donald Trump has announced plans to impose a 10% tariff on Chinese goods starting February 1, citing concerns over fentanyl trafficking from China to Mexico and Canada. This announcement has led to significant declines in Chinese stock markets, with the Shanghai Composite dropping 0.89%, the Hang Seng Index falling 1.78%, and the CSI 300 Index closing down 0.9%. The Chinese yuan also weakened against the U.S. dollar. Trump also indicated that the tariffs could be tied to negotiations over the sale of TikTok's U.S. operations to an American company. In response, Chinese regulators unveiled a plan to stabilize their stock markets by attracting medium- and long-term investments, involving entities such as commercial insurers and mutual funds. Meanwhile, other global markets showed mixed reactions, with Tokyo's Nikkei 225 gaining 1.58% and Mexico's MEXBOL index experiencing a slight decline of 0.36%. Trump also announced a $500 billion AI infrastructure investment initiative. The uncertainty surrounding U.S.-China trade relations continues to weigh on investor sentiment globally.
