China’s Ministry of Commerce has extended two investigations into U.S. trade practices by three months until December 27, citing the complexity of the cases, according to official statements dated September 27 and released this week.
The probes, launched on March 27, examine American measures that Beijing says disrupt global industrial and supply chains and hinder trade in green products. They were framed as reciprocal counter-investigations to two U.S. Section 301 probes initiated earlier that month by the Office of the U.S. Trade Representative. One U.S. investigation targeted alleged structural excess capacity in manufacturing across China and 15 other economies; the other examined claims that China and nearly 60 other economies failed to effectively block imports produced with forced labor.
Chinese authorities said at the time that preliminary evidence pointed to U.S. actions including restrictions or bans on high-tech exports to China, limits on bilateral investment in key sectors, curbs on exports of green products to the United States, delays in deploying new energy projects, and constraints on related technological cooperation. Some of these practices, Beijing argued, may violate World Trade Organization rules and other bilateral economic agreements. The ministry indicated it would take corresponding measures based on the findings to protect Chinese commercial interests. Under China’s rules on foreign trade barrier investigations, cases are normally concluded within six months but may be extended in complex circumstances.
The timing of the extension is notable. It comes just days after U.S. President Donald Trump hosted Chinese President Xi Jinping in Washington for a state visit — their second summit of the year. The leaders and their teams agreed to prolong a broader trade truce by two months through January 10 and to pursue reciprocal tariff reductions on roughly $60 billion of goods ($30 billion on each side). The package covers non-sensitive items ranging from U.S. agricultural products, coal and certain consumer goods to Chinese toys, household appliances and holiday decorations. Officials described the arrangement as creating space for further talks on market access, financial services and agricultural purchases, while both sides continue to manage remaining frictions.
The original truce, first struck in 2025 after a sharp escalation that pushed some tariffs above 100 percent, has already been extended multiple times. It has involved mutual rollbacks of certain high tariffs, suspensions of additional restrictions, Chinese commitments on rare-earth supplies and agricultural purchases, and a pause on some retaliatory steps. Analysts view the latest probe extensions as a deliberate de-escalation signal: by delaying potential findings and any resulting countermeasures, Beijing avoids injecting fresh tension into a relationship still marked by cautious cooperation and unresolved disputes
