China’s Ministry of Commerce issued four trade measures against the United States on Wednesday. It tightened export licensing on drone components, sanctioned six American entities, blacklisted a US testing laboratory, and opened a national security investigation into imported office equipment. It is the broadest single-day retaliation package Beijing has assembled this year.

The ministry said the response targeted measures by the Federal Communications Commission and the Department of Homeland Security, and called it “generally restrained”. A spokesperson said the FCC had repeatedly restricted Chinese telecommunications operations, testing laboratories, unmanned aerial vehicles, consumer-grade routers and submarine cables, and had recently added restrictions on robotics equipment and power inverters. The immediate triggers were an FCC ban on imports of Chinese drones and a DHS decision to add 43 Chinese companies to the Uyghur Forced Labor Prevention Act entity list.

Announcement No. 34 is the mildest of the four in law and the most disruptive in practice. Exports to the US of drones, their key parts and components, and related technologies already on China’s dual-use control list now face case-by-case strict review, with no eligibility for licensing facilitation. It took effect immediately. The ministry cited national security and non-proliferation obligations.

Nothing new was added to the control list. What changed is licensing, and this is critical. Removing facilitation turns a routine approval into an open-ended queue. That disrupts supply without an embargo. Beijing used the same mechanism on rare earths last year. Two further options remain available: a presumption of denial, then prohibition.

Order No. 2 matters most. Six US entities were placed on the countermeasure list for assisting Xinjiang-related sanctions: Applied DNA Sciences, Stratum Reservoir, Altana Technologies, the Responsible Business Alliance, Verite Group and Human Rights in China.

Read the list by function. It is cotton DNA and isotopic traceability, geochemical isotope testing, supply chain mapping, the body that writes responsible sourcing audit standards, and the organisation that conducts the audits. Beijing has not sanctioned importers or brands. It has sanctioned the evidence base that US forced labour enforcement depends on.

UFLPA works on a rebuttable presumption. Rebutting it needs supply chain documentation, origin testing and third-party audit. If Chinese entities cannot transact with the Responsible Business Alliance or Verite Group, those audits become hazardous for the audited party to permit. Importers will struggle to assemble the evidence. Detention rates rise.

The target was chosen because it is cheap. Xinjiang cotton is already largely shut out of the US market, so Beijing gives up no sales by making verification unavailable. This is what restraint looks like in practice. China picked the retaliation that costs it least.

The read-across is to the EU Forced Labour Regulation, which applies from 14 December 2027. Its structure is less forgiving than UFLPA’s. Where an operator does not supply the information requested, the competent authority may decide on the basis of the facts available to it. A supplier legally barred from cooperating is indistinguishable, on the file, from one that refuses.

Order No. 3 is narrower. It named one firm, Compliance Testing LLC, under the Anti-Foreign Sanctions Law, for assisting FCC measures. Chinese organisations and individuals may not transact or cooperate with it. Separately, the National Certification and Accreditation Administration suspended factory follow-up inspections carried out by US certification bodies under the China Compulsory Certification scheme.

Together these make conformity assessment a retaliation instrument. Testing and certification recognition has been treated as purely technical, insulated from trade politics. That no longer holds in either direction. Article 6 of the WTO agreement on technical barriers to trade encourages recognition of other members’ conformity assessment results. Neither side will litigate it.

Announcement No. 33 has the broadest application. It opens a foreign trade national security investigation into imported office equipment with printing and copying functions installed with foreign system software. It is the first such investigation China has run. Foreign system software means driver and embedded software developed, tested or maintained by foreign persons or entities.

The test is software provenance, not the origin of the goods. So the measure is indifferent to where a machine is assembled, and to any tariff engineering a manufacturer has already done. It also means the incidence falls on Japan. Ricoh, Canon, Epson, Konica Minolta and Kyocera dominate the segment. None of them had anything to do with the FCC.

The investigation covers import volumes, the effect on national security interests, reliance on foreign supply, the state of the domestic industry, and that industry’s capacity to meet demand. It must conclude within 12 months, extendable in special circumstances. Interested parties have 30 days to comment. The reference to domestic capacity is the clearest indication of intent. This is an import restriction instrument with a substitution objective attached. Section 232 serves the same function in Washington.

None of this was unprepared. On 22 June the commerce and finance ministries restricted 56 US entities in defence, aerospace, unmanned systems and rare earths, including Red Cat Holdings, Teal Drones and USA Rare Earth. It followed the Pentagon’s expansion of its Chinese military companies list. Unreliable entity list designations reached 67 in 2025, against three in 2024. In May the ministry issued its first blocking order, barring compliance with US sanctions on five Chinese companies.

The package comes ahead of an expected visit by President Xi Jinping to the US in September, and everything here is calibrated: every measure can be unwound administratively. None imposes a tariff or a formal ban. What has changed is the instruments Beijing will now use.
