President Donald Trump said he plans to announce new tariffs on Chinese goods within hours, renewing pressure in a trade dispute that has already strained global markets and supply chains. He said the move is tied to national security concerns and what he described as persistent trade imbalances.

The announcement comes as Washington and Beijing remain locked in a broader competition over trade, technology and industrial policy. Any new duties could raise costs for importers, ripple through consumer prices, and deepen uncertainty for companies that rely on Chinese manufacturing.

Tariff threats have long been a central feature of Trump’s approach to China, which he has framed as necessary to defend U.S. economic and strategic interests. Critics, however, warn that aggressive trade measures can also hurt American consumers and businesses while offering no clear long-term solution to structural disputes.

The latest move underscores how quickly tensions between the world’s two largest economies can spill into broader economic and geopolitical risk. Markets will be watching for the size, scope and timing of the new duties once Trump makes the announcement.
