US export control debate could allow Chinese firms legal access to Nvidia's Blackwell AI chips

A potential loophole in U.S. export controls could allow Chinese companies to legally acquire Nvidia's advanced AI chips, such as the Blackwell processor, from overseas. This issue has sparked intense debate within the U.S. government, according to sources familiar with the matter.

The core of the dispute lies in whether the Trump administration significantly reduced the scope of its restrictions on China's tech industry beyond what was publicly disclosed. If a loophole exists, Chinese firms like Alibaba might be able to legally purchase servers equipped with Nvidia's latest AI chips in most countries outside of China.

AI chip sales to Chinese companies' global controls remain in effect.

The controversy was highlighted by an unusual memo from the U.S. Commerce Department's Bureau of Industry and Security (BIS) on May 31. The memo stated that global controls on AI chip sales to Chinese companies remain effective, a response to inquiries about the validity of existing regulations. However, the document also revealed that the Trump administration's export controls on AI chips for China operated under policy uncertainty and a lack of consistency, leading to months of internal debate.

There is fundamentally no such loophole.

The problem arose because the Trump administration's BIS stopped enforcing the Biden administration's AI Diffusion rule. While BIS did not formally abolish the rule or prepare a replacement, it had attempted to draft alternative regulations twice without success. The administration is now investigating whether companies have exploited this situation to supply advanced AI chips, like Nvidia's Blackwell processors, from locations such as Singapore and Malaysia to Chinese firms.

A BIS official refuted the existence of such a loophole, asserting that exporting AI chips to Chinese companies without U.S. government authorization violated export control regulations even before the memo's release. Another potential loophole is also being discussed internally, related to the decision to stop enforcing the AI Diffusion rule. Officials worry this could allow foundries like TSMC and Samsung Electronics, which manufacture chips for companies like Nvidia, to legally produce advanced semiconductors for Chinese companies such as Tencent. Saif Khan, former Director for Technology and National Security at the White House National Security Council during the Biden administration, noted that the issue is not the abolition of the rule itself, but the practical weakening of its effectiveness due to the lack of enforcement of a separate AI chip export rule.

The essence of the problem is not the abolition of the rule itself, but the practical weakening of its effectiveness.
