US-China AI War: Inside the Battle for Global Tech Dominance

The world’s two largest economies are locked in a fierce competition to win the global AI race. It’s a competition for military dominance, global power and who ultimately will shape the most “consequential technology” of the 21st century, spanning the full tech stack, cybersecurity, semiconductor leadership and data center build-out. "The AI race is no longer just a competition between companies and startups," Kyle Chan, a fellow at the John L. Thornton China Center at the Brookings Institution, said on July 30 on the Beijing Brief podcast.

" That competition crystallized with the release of China’s Moonshot AI’s Kimi K3 in mid-July. 4% drop in the Nasdaq on July 17 as investors sold off chipmaker stocks. Nvidia Corp. (NASDAQ: NVDA ) shares fell more than 2%, briefly pushing its market value below Apple Inc.

could sanction Chinese firms over such conduct. Chinese officials pushed back against the allegations. ” Some AI researchers questioned the accusation on technical grounds. Braden Hancock, a researcher at the Laude Institute, told TechCrunch Fable had only been public for about two weeks before K3 shipped.

That is too short for large-scale distillation, he said. How Good Is K3? Behind the political fight over the allegations is a technical one: how good is K3, really? “Kimi K3 is likely the most capable Chinese model, and the best open-weight model,” Chris McGuire, a senior fellow at the Council on Foreign Relations, said on July 31.

S. ” That shows China is not falling further behind in the AI race, McGuire said. ," he added. But that progress may be less independent than it looks, McGuire said.

S. technology, not less, to maintain its position, he added. Open Source Vs. Closed Source K3’s release has ignited a debate in Washington and Silicon Valley over open source models.

" That buildup is the physical backbone of America’s AI edge. Public resistance could slow the very infrastructure Washington needs to outpace China.

Data Center Opposition A Gallup poll found seven in 10 Americans oppose an AI data center in their local area. Separate polling from Emerson College found opposition nationally jumped from 42% to 63% in eight months. "The data center buildout is accelerating, and public opinion will shape permitting, regulation, and legislation at every level of government," researchers at Rainey Center said in May. " The contrast with China is stark.

The Chinese public is roughly twice as optimistic about AI’s benefits as their American counterparts, according to Stanford’s Institute on Human-Centered AI. AI is diffusing into daily life in China more quickly than in the United States, the National Bureau of Asian Research said in September 2025.
