Trump threatens to massively increase tariffs on China, causing the US stock market to plummet in response.

President Trump threatened on Friday to impose "massive tariff increases" on goods imported from China on the social media platform Truth Social, citing China's plans to impose new control measures on rare earth exports. In his post, Trump stated that if Beijing moves forward with export restrictions, the United States will "take the most severe economic countermeasures in history." Analysts believe that this statement indicates a further escalation of tensions in the US-China trade relationship, quickly dampening expectations for an improvement in relations between the two countries. Affected by the news, the US stock market fell sharply. The Nasdaq dropped over 2%, the S&P 500 fell 1.6%, and the Dow fell over 1%. Investors are concerned that if the US-China trade dispute escalates further, it could further impact global supply chains and bring new uncertainties to the already fragile world economy. Market observers point out that Trump's threat on rare earths is not only symbolic, as rare earths are essential raw materials for key industries such as electric vehicles, batteries, and semiconductors, core areas of the technological and industrial competition between China and the US. If substantial friction occurs in this area between the two sides, the global high-tech manufacturing industry could face a chain reaction.
