The US Department of Homeland Security published an administrative order on October 19, 2026 requiring federal civilian agencies to remove DeepSeek-related technology from their information technology systems and prohibiting the procurement of the company’s products and services. The order was originally issued on July 24, 2026 and covers agencies including the Treasury, State and Justice departments, while explicitly excluding the Department of Defense. China’s Foreign Ministry said it would safeguard the rights and interests of Chinese companies and opposed politicising technology and trade issues.

[What We Know]

• Scope of the order: The directive applies to federal civilian agency IT systems, covering both direct purchases and third-party products and services built using the company’s technology. The Treasury, State and Justice departments are among the agencies affected; the Department of Defense is excluded.
• Security rationale: DHS states that the firm’s models “present multiple threat vectors,” citing concerns over potential access to sensitive data by Chinese authorities and potential malware or other security vulnerabilities. The order references open-source research identifying several critical vulnerabilities in the company’s iOS application.
• Preceding restrictions: Since the company burst onto the scene in early 2025, US government restrictions have tightened progressively. The Defense Information Systems Agency moved to block model access in January 2025, Commerce Department bureaux told staff the product was banned on government devices in March, and Congress restricted its use in intelligence community systems in December 2025.
• Beijing’s response: Foreign Ministry spokesperson Mao Ning said China would safeguard the rights and interests of its companies and that China “consistently opposes the over-generalization of national security as well as the politicization of science, technology and trade issues.”
• Company background: The firm established itself through a low-cost, high-performance open-weight model approach in early 2025 and later built influence in the global open-source ecosystem through a series of reasoning models, making it a central target of US technology restrictions.

[Wider Perspective]

The significance of this order extends beyond the fate of a single company. It marks the shift in the US-China artificial intelligence contest from computing hardware export controls down to software-layer exclusion. Previous US policy tools focused primarily on restrictions on advanced chips and semiconductor equipment, aiming to restrict upstream compute supply. This order instead targets models and applications already deployed on government endpoints, amounting to a retrospective sweep of installed software assets. Combined, the two categories of tools widen the contest from whether compute can be purchased to whether a specific algorithm can be used at all.

The most significant spillover effect concerns third-party supply chains. The order’s wording covers “third-party products and services developed using the company’s technology,” a clause with substantial reach. Many enterprise software packages, cloud services and smart devices abroad have embedded open DeepSeek models for cost reasons without being regarded as direct purchasers of the company’s products. If such embedded use is deemed non-compliant, companies face the cost of swapping models, changing vendors or building in-house inference capacity, expanding the scope of procurement compliance reviews considerably. Auditing this “indirect dependency” is far harder than tracing direct purchases, making the gap between announced policy and actual enforcement likely to persist.

On the industry landscape, the restriction on one of the most prominent open-weight Chinese models has effects well beyond the two countries involved. Developers across Europe, Latin America and the Middle East rely heavily on its open model weights under cost constraints. If the US agency move is treated as a precedent, other jurisdictions may commission their own assessments, pushing the open-source model ecosystem toward increasing stratification along geopolitical lines. For the company itself, the measure pushes it toward a model of self-funded compute and overseas commercial revenue; painful in the short term, but potentially accelerating technical independence over the longer term.

[Viewpoints Compared]

• US government position: DHS grounds the order in data and cybersecurity concerns, arguing that the measures prevent sensitive government data from leaving American systems and that the models themselves present technical risks — a national security rationale rather than straightforward trade protection.
• Chinese position: The Foreign Ministry explicitly opposes politicising technology and trade issues and states that China will protect the rights and interests of its enterprises, while stopping short of a detailed counter-response, leaving room for further diplomatic exchanges.
• Industry concerns: Enterprise software and cloud providers are most focused on how “indirect dependency” is defined, fearing that vague compliance boundaries force costly rework, and they want clearer implementation guidance and transition periods.
• Open-source community: Developers are watching whether open-weight models can continue to circulate within compliant frameworks. Some argue that overly broad restrictions weaken the efficiency of open collaboration and could push more technical work into closed ecosystems.
