Trade talks to test US-China leverage on rare earths, tariffs, and AI

While this high-level U.S.-China trade engagement is unlikely to yield breakthroughs, it will accelerate the decoupling of global semiconductor supply chains. Technically, any U.S. leverage on rare earth exports could disrupt China’s access to critical materials like sputtering targets and CMP slurries, inflating mature-node production costs. Compliance-wise, equipment giants such as Lam Research may need legally segregated operational units for each market, adding 15–20% overhead. Strategically, TSMC and Samsung are poised to double down on localized capacity in the U.S., Japan, and Europe to hedge geopolitical exposure. Over the next 12–24 months, even minor tariff adjustments won’t reverse the deepening tech barriers in AI chips, EDA tools, and advanced packaging—signaling not détente, but a refined phase of strategic disentanglement.
