Washington's effort to keep its most advanced artificial intelligence out of China's hands is running into an awkward possibility: it may be speeding China up.
The crackdown
The Commerce Department has clarified that its ban on exporting Nvidia's most advanced "Blackwell"-generation AI chips to China extends to the overseas subsidiaries of Chinese companies — closing what a former U.S. official called a loophole that Chinese firms had used to buy restricted chips abroad, Al Jazeera reported. Nvidia said its "sales and vetting process is correct" and that it requires licenses for controlled shipments to China-based firms. The chip controls sit alongside a broader administration push to restrict access to frontier U.S. AI systems, which officials describe as a national-security imperative.
The security case
The White House has framed the measures as a response to documented theft. Its science-and-technology office accused Beijing of running "deliberate, industrial-scale campaigns" to copy U.S. frontier AI by bombarding American models with queries to train cheaper imitations — a technique known as "distillation," Nextgov reported. AI companies have separately reported large-scale efforts by Chinese firms to extract knowledge from their models through networks of fraudulent accounts. Supporters argue the most advanced models and the chips that run them could meaningfully boost an adversary's cyber and military capabilities, and must be guarded.
The backfire risk
But analysts warn the controls may cede ground rather than hold it. As access to U.S. systems tightens, Chinese developers have pressed their advantage in open-weight models that anyone can download and run without fear of being cut off. The Chinese lab DeepSeek has drawn a large new funding round, by CNBC's account, which framed the crackdown as opening a door for Chinese model-makers, and usage data from developer platforms shows Chinese open models capturing a sharply rising share of global traffic. European and Canadian labs, meanwhile, are pitching themselves as "government-proof" alternatives that cannot be switched off by U.S. executive order — a reputational edge over American providers.
The unresolved trade-off
U.S. labs still hold the lead at the cutting edge, and the controls do raise real costs for Chinese firms seeking the fastest chips. The open question is whether restricting access mainly protects American advantage or mainly hands China's domestic and open-source ecosystem a marketing gift in the price-sensitive markets of Asia, Africa and Latin America. Trump and China's Xi Jinping are expected to meet in the coming weeks, with chip controls and intellectual-property disputes high on the agenda — a sign that, for all the unilateral action, the contest's terms are still being negotiated.
