China’s Ministry of Commerce announces it is adding 20 Japanese entities to its export control Entity List, barring or restricting exports of certain “dual-use” items that can serve both civilian and military purposes. In a statement issued Monday, the ministry says the listed organisations have participated in enhancing Japan’s military capabilities and frames the action as part of efforts to protect China’s national security and fulfil international non-proliferation obligations.

The additions include Japanese defence-related bodies such as the National Institute for Defense Studies, along with Mitsubishi Electric Defense and Space Technologies Corporation, among other companies and organisations. China also places a further set of Japanese entities on a separate watch list, according to multiple outlets.

The move comes amid a months-long dispute between Beijing and Tokyo over trade and security issues. One report notes China recently imposed export curbs on 10 US firms before expanding restrictions to Japanese entities. Overall, outlets describe the decision as escalating export-control tensions while citing similar stated objectives of national security and non-proliferation.
