## Key points

- 美國商務部封堵一項漏洞，使先進人工智慧晶片得以出口至中國境外子公司。
- 新規定要求對中國總部企業無論全球位置均須嚴格取得許可。
- 這是一次未公告的週末發布，收緊對Nvidia與AMD等公司人工智慧晶片的管控。
- 該漏洞源自川普時代政策，存在約一年，可能涉及數十萬顆晶片。

The U.S. Department of Commerce has taken decisive action to close a loophole that may have inadvertently facilitated the export of advanced AI chips to Chinese firms' subsidiaries located outside China. This includes cutting-edge processors from industry leaders like Nvidia and AMD. Released unexpectedly over the weekend, the department's new guidance aims to enforce stringent license requirements for Chinese HQ entities, regardless of their geographic location. This move signals a tightening of export controls amidst ongoing U.S. efforts to restrict China's access to crucial AI technology. The update also interacts with policy left from the Trump administration, which some argue had allowed the predicament to persist for nearly a year. While Nvidia and AMD have yet to comment, industry experts suggest that the issue potentially enabled Chinese access to hundreds of thousands of these chips. (With inputs from agencies.)

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