The United States has issued a sweeping global diplomatic warning about what it describes as systematic efforts by Chinese artificial intelligence companies, including the high-profile startup DeepSeek, to steal and replicate advanced American AI technology through a technique known as model distillation.
According to a U.S. State Department diplomatic cable dated April 24, 2026, and sent to American diplomatic and consular posts worldwide, Chinese firms are engaged in widespread intellectual property theft targeting leading U.S. AI laboratories. The cable directs U.S. diplomats to raise these concerns directly with foreign governments, warning of the security and economic risks posed by AI models derived from stolen proprietary technology.

The cable specifically highlights DeepSeek, a rapidly rising Chinese AI company known for releasing powerful and cost-effective open-source models. OpenAI had previously warned U.S. lawmakers that DeepSeek was actively targeting leading American AI developers, including itself, in an effort to replicate their advanced models at a fraction of the original development cost. Other Chinese companies flagged in related concerns include Moonshot AI and MiniMax.
The technique at the center of the allegations is called “extraction and distillation.” In this process, adversaries reportedly use massive amounts of queries and computing resources to extract capabilities from frontier U.S. models such as those powering ChatGPT. The resulting distilled models can perform well on certain benchmarks while being significantly cheaper to operate and deploy. However, according to U.S. officials, they often lack the full sophistication, safety features, and reliability of the original systems.
The diplomatic cable explicitly states its purpose is to “warn of the risks of utilising AI models distilled from U.S. proprietary AI models, and lay the groundwork for potential follow-up and outreach by the U.S. government.” A separate demarche has also been delivered directly to Beijing.
This latest action builds on earlier White House accusations of “industrial-scale” AI theft by entities primarily based in China. In recent weeks, senior officials including Michael Kratsios, director of the White House Office of Science and Technology Policy, have publicly highlighted coordinated campaigns involving tens of thousands of proxy accounts used to evade detection while systematically distilling capabilities from American AI systems.
For the global technology sector, the implications are substantial. Governments and companies considering or already using Chinese AI tools may now face increased scrutiny from allies aligned with Washington. This could lead to new compliance requirements, supply chain audits, and restrictions on procurement in sensitive sectors such as defense, finance, and critical infrastructure.
DeepSeek has emerged as a particular flashpoint. The company gained international prominence with its efficient models that rival much larger players in performance while operating at lower costs. Critics argue this rapid progress may stem in part from unauthorized access to U.S. model outputs rather than purely original research and development.
Chinese officials have strongly rejected the accusations. The Chinese Embassy in Washington described the claims as “groundless” and characterized the U.S. actions as deliberate attempts to hinder China’s legitimate technological development. Beijing maintains that its AI advancements are the result of domestic innovation and open collaboration.
The timing of the State Department cable is notable. It arrives amid broader U.S.-China technology tensions and ahead of anticipated high-level diplomatic engagements. The Trump administration has made protection of critical technologies a cornerstone of its economic and national security strategy, continuing aggressive enforcement even while pursuing other areas of bilateral dialogue.
Industry analysts suggest the warning could accelerate efforts by U.S. allies to diversify away from certain Chinese AI providers. It may also prompt greater investment in domestic AI capabilities across Europe, Asia, and other regions wary of entanglement in the superpower rivalry.
From a market perspective, the development adds another layer of uncertainty for investors in the global AI ecosystem. Shares of major U.S. AI companies have shown resilience due to perceived technological leads, but any escalation in restrictions or retaliatory measures from China could affect supply chains, chip exports, and international partnerships.
DeepSeek and similar firms have argued that their models are developed independently and that open-source contributions benefit the entire industry. However, mounting allegations from OpenAI, Anthropic, and now the U.S. government paint a picture of coordinated efforts to close the AI gap through intellectual property shortcuts.
As the U.S. continues to share intelligence with American AI firms and explore accountability measures, the diplomatic offensive underscores the strategic importance of frontier AI in the ongoing great-power competition. The coming weeks are likely to see further discussions in allied capitals about balancing innovation, security, and economic ties with China.
