On February 5, 2025, the U.S. announced an additional 10% tariff on imports from Hong Kong, aligning it with similar measures against mainland China amid escalating Sino-U.S. trade tensions. Effective February 4, 2025, these tariffs, imposed under the International Emergency Economic Powers Act, are justified by national security concerns and will remain until the U.S. President resolves the national emergency. While temporary agreements have delayed tariffs for Canada and Mexico, no such relief applies to China or Hong Kong, prompting China to plan retaliatory actions and raising fears of broader global trade disruptions, including potential tariffs on the European Union.
