The Trump-Xi Washington summit was, by the admission of observers across the political spectrum, a substanceless affair dressed in the language of historic achievement. Three days of red carpets, state dinners, tea ceremonies, and tours of the National Archives produced exactly one policy deliverable: a two-month extension of an existing trade truce. On artificial intelligence — the technology both leaders acknowledge could reshape civilization — they agreed on nothing. The opportunity cost is concrete. Rep. Ro Khanna, the top Democrat on the House select committee on China, laid out what a minimal win would have looked like: technical working groups pairing DeepSeek, Moonshot, and Alibaba with Anthropic, OpenAI, and Google, committed to at least a pause on self-improving AI. Khanna believes Xi would have agreed to at least the working groups. Trump had no interest. Both leaders instead affirmed they have no intention of slowing down. The state dinner guest list told its own story. Bernie Sanders catalogued the table: Elon Musk ($928bn), Jensen Huang ($186bn), Lisa Su ($3.5bn), Tim Cook ($3.1bn). American tech royalty was present and accounted for. Their Chinese counterparts were not. No joint technical framework was proposed, no verification regime discussed, no symbolic gesture made toward restraint. Jonathan Czin of the Brookings Institution called it "theatre of the absurd" and noted that two leaders — a septuagenarian and an octogenarian who may never have had first-hand contact with AI — hold the technology's future on their shoulders. Trump's priorities were visible in what he chose to emphasize. He pushed his rebranding of AI as "super intelligence," later claiming on social media that Xi "seems to like" the term. He showed Xi a gallery wall where Joe Biden is depicted as an autopen. He praised Xi's expertise in granite. On substance, Trump said the summit produced "great strides" and that "our farmers are going to be happy" without providing details. The asymmetry in diplomatic treatment was stark. Trump broke protocol to greet Xi plane-side with a red carpet at Joint Base Andrews — a courtesy not extended to democratic allies like Canada. Chinese state media were welcomed into the White House grounds even as CNN, MS Now, and Politico remained barred from access following Trump's press ban the previous week. No joint press conference was held, matching the pattern from Trump's May visit to Beijing. China, meanwhile, is not waiting. Beijing's stated goal is 90% penetration of next-generation smart terminals and AI agents by 2030. Xi acknowledged the "responsibility to develop and manage AI for good" and ensure it remains "under human control," but paired this with no enforcement mechanism, no timeline, and no partnership structure. The rhetoric of restraint absent the architecture of restraint is just rhetoric. Two more meetings are scheduled: the APEC summit in Shenzhen in November and the G20 at Trump National Doral in December. Senate Democrats, led by Chuck Schumer, called the summit a "complete capitulation." The question is whether the next two meetings will produce anything beyond more stone appreciation and more tea — or whether the window for cooperative AI governance will have closed by the time anyone with authority decides to try.
