On October 20, 2026, Foreign Ministry spokesperson Mao Ning, responding at a regular press conference to reports that the US government has asked its agencies to stop using artificial intelligence tools from Chinese companies such as DeepSeek, said that China consistently opposes overgeneralizing the concept of national security and politicizing science, technology, and economic and trade issues, and will resolutely safeguard the legitimate rights and interests of Chinese companies. On the same day, reports said that the US Department of Homeland Security had ordered the removal of DeepSeek-related technology from most government systems and barred civilian government agencies from using DeepSeek and any technology built with its models; the reports said the ban took effect at the end of July and that agencies under the Department of Defense are not covered. Other reports said the order, based on the 2018 Federal Acquisition Supply Chain Security Act, requires civilian agencies to remove DeepSeek and related products from their information technology systems, as well as third-party products and services developed using DeepSeek, with exceptions requiring an application submitted 60 days in advance with reasons stated.
