The US imported more from Taiwan than China for the first time in decades as President Donald Trump’s tariffs reshape trade flows while a global boom in artificial intelligence fuels demand for tech products.

US purchases of goods from China plunged almost 44% in December from a year earlier to $21.1 billion, Commerce Department data showed Thursday. By contrast, shipments from Taiwan more than doubled during the same period to $24.7 billion.

The soaring Taiwanese shipments to the US reflect the huge expansion in supplies of chips and servers for AI companies, which has completely changed the self-ruled island’s trade profile and propelled its near $1 trillion economy into one of the world’s fastest growing.
