China agrees to ease rare earth restrictions in Trump deal as Taiwan's chip role takes center stage again

China’s easing of rare earth export curbs isn’t a concession—it’s a tactical pivot that elevates Taiwan’s semiconductor leverage. While temporarily relieving cost pressures for U.S. power semiconductor makers reliant on neodymium and dysprosium, Washington is fast-tracking domestic refining via MP Materials and Lynas under DoD funding. The real objective? Divert attention from China’s dominance in mature-node materials while pressuring Beijing on advanced lithography and EDA access. TSMC’s sub-3nm capacity becomes the unspoken bargaining chip. Over the next 18 months, expect a bifurcated supply chain: legacy nodes anchored to Chinese inputs, cutting-edge nodes locked into U.S.-Japan-Netherlands ecosystems. Companies without dual-sourcing or local certification strategies risk abrupt compliance ruptures.
