U.S. President Donald Trump and Chinese President Xi Jinping showed differences on AI guardrails at their White House summit on Thursday, September 24, 2026, Yonhap reported from Washington on Friday, September 25.
During a welcome ceremony, Xi said AI must remain “under human control.” China and the United States are both leading nations with the capability and responsibility to develop and manage AI for good, and to ensure AI development stays under human control and serves people’s well-being, Xi said, according to Yonhap.
Trump has opposed additional AI guardrails and cast AI safety fears as a “hoax,” Yonhap wrote. Ahead of the meeting, Trump posted on Truth Social that “Super Intelligence (SI) will be a big topic of discussion, but I want to leave it exactly where it is. That is China’s position also. Our guardrail is the DOJ!”
At the U.N. General Assembly on Tuesday, Trump said the United States “totally rejects any attempt to construct a globalist scheme to control AI” and will not stifle AI growth, Yonhap noted — territory AI Tech Daily covered in Trump UNGA Super Intelligence. Separately, AITD has a live brief on the Trump–Johnson tech CEOs AI meeting calendared for later in September; this summit brief is distinct from that convening note.
Reports have said the Trump administration proposed a “notification mechanism” for bilateral communication on dangerous AI events with security implications, Yonhap wrote. No concrete U.S.–China AI agreement was announced from the summit.
This brief covers the Yonhap-reported summit divergence on human control versus additional guardrails, Trump’s DOJ framing and UNGA line, the carefully attributed notification-mechanism reports, and the absence of an announced bilateral AI deal — not a claim that either side accepted the other’s AI governance model.
