China escalates US chip war with new probes
Beijing launches dual investigations into US semiconductors ahead of trade talks, raising supply chain risks.

Headline
Beijing launches dual investigations into US semiconductors ahead of trade talks, raising supply chain risks.
Context
China’s Ministry of Commerce has opened two major investigations into the United States’ semiconductor industry, escalating tensions in the long-running trade dispute between the two countries. The ministry announced an anti-dumping probe into US-made analogue integrated circuit (IC) chips, which are widely used in consumer electronics, cars and industrial equipment. A second anti-discrimination investigation will review US policies restricting Chinese chipmakers, including export controls and investment bans justified on national security grounds.
Evidence
Pending intelligence enrichment.
Analysis
The move comes just days before planned high-level trade talks, signalling Beijing’s intent to confront Washington’s approach to technology trade. Analysts say US companies such as Texas Instruments and Analog Devices could face tariffs or restrictions if the probes find evidence of unfair practices. Posts on X (formerly Twitter) from financial analysts highlighted potential market turbulence, noting that semiconductor stocks like Nvidia and AMD dipped in after-hours trading following the announcement.

They come as former US President Donald Trump has threatened to impose tariffs of up to 300% on semiconductor imports, part of his administration’s effort to curb China’s technological rise.
Key Points
- China’s Ministry of Commerce to probe alleged dumping of US-made analogue IC chips.
- Investigation also targets US restrictions on Chinese semiconductor firms.
Actions
Pending intelligence enrichment.
