China Tightens Frontier AI Export Controls

China is treating frontier model internals as strategic technology while preserving overseas commercialization through hosted access. That creates a sharper divide between exporting model artifacts and exporting model capabilities.

• –The proposal covers large models, agents, compute clusters, and information-processing technologies—not just weights and source code.
• –Reporting indicates restrictions could apply to models trained on important data with 2 trillion-plus parameters or top-tier global rankings. [AP](https://apnews.com/article/china-export-restrictions-ai-chips-solar-us-5ac381c0d6c6628bbea2e0da7d855a5b)
• –Official guidance says API calls, apps, web interactions, SaaS, and lightweight edge deployments generally fall outside model-technology export controls. [MOFCOM Q&A](https://www.mofcom.gov.cn/zwgk/zcjd/art/2026/art_b11d5c1e9374421e93e85dc87eba6e38.html)
• –Developers and labs moving weights, licenses, training artifacts, or ownership across borders will face new compliance and provenance work.
• –The policy could pressure Chinese companies to choose between global open-weight distribution and tighter domestic control.
