China Trade Investigations Escalate Response to US Section 301 Probes

China trade

China trade investigations launched on 27 March marked a sharper response to US Section 301 actions targeting Chinese supply chains and green product trade. Beijing opened two probes after Washington initiated investigations tied to overcapacity and alleged forced labour-linked imports.

The China trade investigations came as market participants watched for possible changes to China’s rare earth export policy ahead of a planned Trump-Xi summit in Beijing in May. Rare earth buyers remain sensitive to any regulatory signal because China dominates separation and processing for many medium and heavy rare earths.

The new probes show that China-US trade tensions are moving deeper into strategic industrial supply chains. The dispute now covers green products, high-technology exports, investment restrictions, forced labour rules, and access to critical minerals.

Beijing Targets US Measures on Supply Chains and Green Products

China’s commerce ministry said its investigations would examine US practices affecting global production and supply chains. It said these measures included restrictions on Chinese products entering the US, limits on high-technology exports to China, and restrictions on two-way investment in key sectors.

The ministry also said the US had adopted practices that obstructed trade in green products. These included barriers to exports, slower deployment of new energy projects, and limits on technical co-operation linked to green technologies.

Beijing argued that some US actions could harm Chinese enterprises and may violate World Trade Organisation rules or other bilateral and multilateral trade agreements. The response shows that China is framing the dispute not only as a tariff issue, but as a broader challenge to industrial access and technology flows.

Rare Earth Markets Watch Trump-Xi Summit Risk

China trade investigations also carry direct implications for rare earth and critical mineral markets. Market participants expect rare earths to be one of the issues discussed when US president Donald Trump and Chinese president Xi Jinping meet in Beijing on 14-15 May.

China placed seven medium and heavy rare earths under a strict dual-use export licensing regime in April 2025. Those controls triggered supply concerns and sharply higher ex-China prices before Beijing relaxed them in November after earlier talks between the two leaders in South Korea.

European buyers may now increase restocking if they expect renewed export controls or tighter licensing. This risk is particularly important for rare earths used in high-end manufacturing, defense systems, electric motors, magnets, and advanced industrial equipment.

The Metalnomist Commentary

The China trade investigations show that trade policy and critical minerals policy are now deeply connected. Rare earths remain one of Beijing’s strongest leverage points, and any renewed restriction could quickly reshape procurement behavior across Europe, Japan, Korea, and the US.
