US Bans DeepSeek on Government Systems, Expanding Agency-Level Restrictions

The US government has issued a government-wide ban on the use of DeepSeek in agency computer systems, extending earlier prohibitions by the Commerce Department and Navy. This marks a formal federal policy shift, likely driven by data-security and national-security concerns over AI tools linked to China. The move signals tightening US-China tech decoupling in AI, with potential implications for federal procurement and broader market access.
