When Donald Trump greeted Xi Jinping at Andrews Air Force Base — a reception protocol used only a handful of times in US history — the gesture telegraphed how much weight Trump places on personal rapport as a diplomatic instrument. Xi, by contrast, sent his vice president to meet Trump in Beijing last May. The asymmetry is instructive: Trump believes the personal relationship is the relationship; Beijing treats it as theater layered over structural competition. The summit's concrete output is thin. The trade truce, originally set to expire in November, gets extended to January. This had been widely expected. The "Busan deal" framework from last October — where Trump paused further tariffs in exchange for Xi easing rare-earth export controls — remains the operative arrangement. But the Financial Times reports the US believes China has not fully honored its rare-earth commitments, with shipments declining and fears of renewed supply choking. Rare earths remain Beijing's most potent asymmetric lever. On trade, Trump offered nebulous comments about "progress" but no sector-specific deals have materialized. Reports of an expected $30 billion in two-way tariff cuts remain unconfirmed. The US-China "Board of Trade" announced in May is reportedly operational, with initial product lists including US agricultural goods and Chinese LNG and low-tech goods. China also wants access to cutting-edge US-made chips for frontier AI development — a demand that cuts directly against Washington's technology containment strategy. AI cooperation received the most aspirational language and the least substance. A US-China AI "dialogue" was announced after meetings between Treasury Secretary Bessent, Trade Representative Greer, and Chinese Vice Premier He Lifeng. No timeline for the next meeting exists beyond a possible APEC venue in November. Trump has called AI safety warnings a "hoax," reducing any incentive for China to slow its own development. The trust deficit makes verification of any agreement effectively impossible. Taiwan remains the summit's shadow agenda. Trump has delayed a $14 billion arms package for Taiwan passed by Congress in January, calling it a "good bargaining chip." Chinese state media reported Xi asked Trump to "adhere to the correct position of opposing Taiwan independence" — language that, if accepted, would represent a significant shift from the current US formulation of "not supporting" independence. The distinction between "opposing" and "not supporting" is where decades of strategic ambiguity live. Beijing's strategy is visible in the pattern: summit after summit of positive optics that freeze the rivalry in place. Chinese policymakers have begun calling this "constructive strategic stability" — a framework that lets Beijing pursue technological self-sufficiency and industrial policy while the bilateral relationship remains too warm to rupture. As MERICS analyst Aurelio Insisa noted, the trade truce foundations are "brittle" and unlikely to survive beyond Trump's presidency. Future administrations, even Republican ones, will likely deviate from Trump's personalized approach. The structural picture is clear: neither side can decouple fast enough to eliminate mutual supply-chain leverage. China's rare-earth dominance and manufacturing scale versus America's chip design ecosystem and financial system create what Eurasia Group's Dominic Chiu calls "mutual choke points" that enforce managed stability. The question is whether managed stability serves Beijing's timeline — consolidating technological capability while the US burns diplomatic energy on personal summitry — better than it serves Washington's.
