US Bans Civilian Agencies From Using DeepSeek
KEY FACTS
- The US Department of Homeland Security issued a directive barring federal civilian agencies from procuring DeepSeek products.
- The directive requires agencies to immediately remove DeepSeek and related third-party products from their technology stacks.
- The directive was originally signed in late July of this year and covers the Treasury Department, the State Department, and the Department of Justice.
- The Department of Defense is not covered by the ban, after several agencies had already restricted DeepSeek on their own.
- China's Foreign Ministry responded by saying it opposes overstretching the concept of national security and politicizing science and technology issues.
PHYSIX OBSERVATION
From Congress and the Commerce Department to the Department of Homeland Security, America's blocking of DeepSeek has escalated from isolated bans to a systematic purge, and the explicit exclusion of the Department of Defense shows that it is still defined as a data and supply-chain risk rather than an operational threat. For Chinese AI going global, the government market is essentially closed; the real signal is that compliance and localized deployment will become hard thresholds for entering Western markets.
