China announces retaliatory measures against the United States, imposing export controls on 10 American companies involved in defence and rare-earth related activities. Chinese authorities say the step is a response to Washington’s expansion of a blacklist that targets certain Chinese firms linked to the country’s military. Multiple outlets report that China also bans government procurement of products from 46 US defence companies. The measures are described as a two-pronged response: restricting exports of dual-use goods to the 10 designated US companies and prohibiting public buyers from purchasing products made by the 46 firms. Reports note the context of heightened economic and strategic tensions between the two countries, with the US action framed as targeting additional Chinese entities and China’s response framed as retaliatory. Some coverage places the announcement in the broader timeline of recent high-level engagement between US and Chinese leaders, while still emphasizing that the new controls and procurement bans escalate the dispute over trade and security-related technologies.
