China imposes export controls affecting Japanese companies amid worsening tensions with Tokyo, according to multiple reports. China places 40 Japanese entities on a control list, saying they contribute to what it describes as China’s “remilitarization” linked to Japan. The controls restrict sales by exporters, including Chinese and foreign firms, of dual-use items made in China to the listed entities. One outlet reports that 20 of the entities are specifically named, including divisions of Mitsubishi Corporation, suggesting part of the broader list targets particular corporate units. The measures come as trade and security relations between China and Japan deteriorate, with both sides trading accusations related to defence and industrial activities. The reports describe the export controls primarily as a legal and commercial restriction on the flow of dual-use goods originating in China. They do not provide details on timing beyond the imposition of the controls, nor on how Japan or the companies named respond.
