本文认为所谓“G2”叙事并不稳定：美国在关税和制裁上的力量与中国在权威治理与地缘杠杆上的力量对峙，双方都把经济技术互赖视为安全风险。特朗普于5月14日至15日的北京会晤只是2026年底前预计四次会晤中的第一次，未来六个月可能为人工智能、供应链、台湾与伊朗定下多年走向。
贸易是议程核心。经历近十年的间歇性争端后，2025年双方关税在双向超过100%后，局势几近全面破裂，随后降为“停火”状态；这一局面被界定为互相脆弱的僵局，因为中国可限制稀土出口，而美国可以制裁高科技出口和金融流动进行惩罚。
最大风险是误判：美国对产能过剩与强迫劳动的调查可能很快触发新税负，而中国5月2日的“阻断措施”对遵守美方制裁的公司设置金融处罚并针对供应链外迁威胁报复。中国在台湾议题上试图以贸易换取让步，并试探美国不可预测性，但若在军售或“台湾独立”表态上让步，将破坏现状而非稳定局面，峰会最终更可能是以“怕彼此伤害”维持最小合作，导致G2像互相挟持而非共同治理。
The article argues the “G2” framing is unstable: U.S. tariff-and-sanctions power is colliding with China’s authoritarian leverage, and both sides now treat their interdependence as a security problem. Trump’s Beijing visit on May 14–15 is only the first of four expected meetings before the end of 2026, and the coming six months may set multi-year directions on AI, supply chains, Taiwan and Iran.
Trade dominates the talks. After nearly a decade of on-again, off-again conflict, 2025 nearly reached rupture when bilateral tariffs rose above 100%, then moved to a truce; this is described as a mutual-vulnerability stalemate because China can constrain rare-earth exports while Washington can sanction high-tech exports and financial flows. As China expands semiconductor self-reliance and dollar de-linking while the U.S. tries to break rare-earth bottlenecks, the strongest likely summit outcome is a reset in predictability and holding tariffs at current levels rather than major cuts.
The major risk is miscalculation: U.S. investigations into industrial overcapacity and forced labor could quickly trigger new duties, while China’s May 2 “blocking measure” threatens firms complying with some American sanctions and punishes supply-chain relocation. China appears ready to bargain over Taiwan for trade concessions, but yielding on arms sales or Taiwan’s status would destabilize the current equilibrium; more likely, outcomes remain narrowly transactional and constrained by fear of economic retaliation, leaving the G2 as mutual coercion rather than effective global stewardship.
