Beijing has announced sweeping trade curbs against the United States, including export controls on drones and a ban on dealings with six American entities, in retaliation for recent US restrictions on Chinese tech.
China has announced a series of economic measures against the United States, including controls on drone exports and a ban on dealings with six American entities.
The move is in response to recent restrictions imposed by Washington.
Tensions are simmering between the world's two biggest economies ahead of an expected visit by Chinese President Xi Jinping to the US in September.
This comes despite signs of warming ties during his meetings with US President Donald Trump in Beijing in May.
China's Commerce Ministry said the sanctions are a response to recent US moves, including a ban by the US Federal Communications Commission (FCC) on imports of Chinese drones, and a decision by the Department of Homeland Security to add 43 Chinese companies to the Uyghur Forced Labor Prevention Act entity list, preventing imports of goods made with forced labour.
The measures "seriously violate the important consensus reached by the two heads of state and severely damage China's legitimate rights and interests," the ministry said in a statement.
"China has no choice but to take necessary countermeasures in response."
Beijing said it was acting with restraint and urged Washington to scrap its measures and cease its "erroneous practices".
It warned of further sanctions if the US rolls out new restrictions against China.
Case-by-case reviews for drone exports
Beijing is requiring case-by-case reviews of exports of unmanned aerial vehicles (UAVs), their key components and related technologies.
These fall on a list of export-controlled dual-use items that can serve both civilian and military purposes.
Six US entities were banned from engaging in trade or other activities with entities in China, including Applied DNA Sciences and the non-governmental group Human Rights in China.
China separately banned Compliance Testing LLC from doing business in the country, accusing it of working with the FCC to harm "China's sovereignty and security," according to the Commerce Ministry.
The ministry also said it was investigating the possible national security impact of imported printing software and office equipment, though it did not name any affected companies.
New rules on safety certification
China's State Administration for Market Regulation said US companies that carry out follow-up factory inspections on behalf of Chinese entities for CCC certification can no longer issue those certifications.
CCC certification is meant to ensure electronic products meet basic safety standards. Under the new rule, US makers of certified electronics will need to hire auditors based outside the US or rely on other non-US designated bodies instead.
In December, the FCC banned imports of new Chinese drones, though it later revised the ban to allow some models through.
Last week, the regulator also announced bans on imports of new foreign-made humanoid robots and power inverters, citing national security risks — a move that in effect targets China.
