The US-China trade war escalated dramatically as President Donald Trump announced a sweeping 100% additional tariff on all Chinese imports. The retaliatory move comes after Beijing restricted supplies of critical technologies, including rare earths processing.
Financial markets reacted violently to the announcement, with a staggering $1.65 trillion wiped out from US stock values. The White House described the measures as necessary countermeasures against China’s aggressive trade actions.
Effective November 1, 2025, the new tariffs will apply to all Chinese goods on top of existing duties. Simultaneously, the administration unveiled stringent export controls covering “any and all critical software” – a significant expansion of trade restrictions.
The tit-for-tat exchange marks one of the most severe phases in the ongoing trade conflict between the world’s two largest economies, reports Chidanand Rajghatta.
