## Key points

- 商務部現對中國企業的海外子公司執行晶片許可規定。
- 數十萬顆先進的 Nvidia 和 AMD 晶片可能已流向中國相關的海外實體。
- 自 2025 年 5 月起存在一個漏洞，允許先進 AI 晶片出口至中國境外的中國子公司。
- 新規定不要求移除或限制現有數據中心中先進晶片的服務。
- 該指導方針特別針對 Nvidia Blackwell、Rubin 及 AMD MI350x 晶片的限制。

The U.S. Department of Commerce on Sunday moved to close a year-old potential loophole it had created that may have led companies to ‌export the world's most advanced chips - like Nvidia's most sophisticated Rubin and Blackwell ​processors, as well as AMD's MI350x - to Chinese entities located outside China. The unexpected guidance suggests the United States' best AI chips may have ⁠been making their way to the subsidiaries of Chinese AI firms based in ​places like Malaysia for almost a year despite broader U.S. efforts to starve Chinese ⁠firms of semiconductors needed to develop critical AI capabilities. The new guidance was posted on the Commerce Department's website on Sunday. It is unclear how many of the chips have been exported in the year that ‌the Trump administration left the door open. One chip industry source with ​deep supply-chain knowledge ‌estimated it was in the hundreds of thousands. In unusual weekend guidance, the Commerce Department said it would enforce license requirements ‌for advanced chips to entities headquartered in China, even when the entities were located outside China. The Commerce Department did not immediately respond to a request for comment. Nvidia and ⁠AMD did not immediately respond to requests ‌for comment. The Commerce Department created the ⁠opening when it announced in May 2025 that it would not be enforcing the AI Diffusion rule issued in ⁠the ⁠last days of the Biden administration. The rule governed global access to AI chips. Chris McGuire, a technology expert and ‌former State Department official, said in a social media post on Sunday: "This is a HUGE problem." He said the loophole allowed the overseas subsidiaries of Chinese companies to buy Nvidia Blackwell ‌chips without ​a license. "Chinese companies have ‌been buying these chips, very likely at scale," McGuire said. In another twist, the new guidance does not require data centers to stop using the chips ​or cut off servicing of the advanced computing items such as servers.

**Companies:** Nvidia, AMD
**Countries:** United States, China, Malaysia
