In a significant escalation of trade tensions, former US President Donald Trump announced on Friday that the United States will impose an additional 100% tariff on all imports from China starting November 1, 2025. The move, which could be implemented sooner depending on China’s actions, will apply on top of existing tariffs. Trump also revealed plans to enforce export controls on all critical US-made software from November. The announcement was made via his Truth Social account, where he emphasized that these measures are part of broader countermeasures under consideration. This decision comes despite recent trade talks between Chinese and US teams in Madrid, Spain, following earlier discussions in Switzerland, Britain, and Sweden. The announcement triggered a sharp decline in US stocks, marking the worst single-day performance since the height of the tariff war in April. Trump’s aggressive stance underscores the ongoing economic rivalry between the two nations, with potential ripple effects on global trade and markets.
