The Scramble for Supply Chain Sovereignty: How the West Is Rewiring Its Economy Around China

On a Tuesday in early May, the European Commission quietly published a draft regulation that would require companies in strategic industries to source critical components from at least three different suppliers — none of them Chinese. The document, portions of which were obtained by the Financial Times, runs to 47 pages of technical specification and political theatre in roughly equal measure. It does not name China directly. It does not need to. The threshold it sets — 65 percent of a given component's value originating in a single country — is designed, industry analysts say, to catch Chinese manufacturers while technically preserving the fiction of trade neutrality.

The same week, the Chinese customs authority in Beijing announced an immediate halt to exports of sulphuric acid, a chemical critical to the production of electric vehicle batteries, to Australia. The decision, reported by SBS News on 18 May 2026, followed a diplomatic dispute over unclear terms and was framed by Chinese state media as a routine inspection matter. Australian battery manufacturers, who had begun scaling domestic production precisely to reduce reliance on Chinese supply, found themselves facing the same calculus their European counterparts had been quietly working through for two years: how to build an industrial base that does not depend on a country that has already demonstrated it will use export controls as a political instrument.

These two events are not coincidental. They are the leading edges of a structural realignment in global manufacturing that is accelerating faster than most governments planned for and most companies can adapt to. The West — led by Brussels and Washington — has decided that the efficiency gains of integrated global supply chains are no longer worth the strategic vulnerability they create. Beijing has reached the same conclusion from the opposite direction: that the leverage embedded in its control of processing capacity for critical minerals and components is an asset worth preserving and, when necessary, weaponising. The collision between those two conclusions is what this article is about.

The Brussels Mandate

The European Commission's proposed regulation, detailed in the FT's reporting on 18 May 2026, would apply to semiconductors, electric vehicle batteries, permanent magnets, solar panels, and a category the Commission calls "strategic raw materials" — a term that covers lithium, cobalt, rare earths, and a dozen other elements without which the clean energy transition cannot function. Companies operating in the EU market would be required to certify that no single country accounts for more than 65 percent of the value of any critical input. The regulation would take effect in stages, with the most sensitive categories facing compliance deadlines as early as 2027.

The political logic is straightforward. Europe spent the first two decades of the 21st century building an economic relationship with China optimised for cost and scale. That relationship delivered cheaper electric vehicles, cheaper solar panels, and cheaper batteries. It also delivered near-total dependency: by 2024, more than 87 percent of EV battery cell manufacturing capacity globally was located in China, according to data from Benchmark Mineral Intelligence cited in the FT reporting. The supply chain disruptions of 2020 and 2021 — initially attributed to the pandemic, later to the war in Ukraine — exposed how quickly that dependency could become a liability. A continent that could not source enough semiconductor chips to keep its own car factories running had no plan for what happened when the chips came from a single country and that country decided, for whatever reason, to slow the shipment.

The Brussels response has been to impose planning requirements that most companies, operating on normal commercial timelines, are not equipped to meet. A senior official at a major European automaker, speaking on condition of anonymity because they were not authorised to comment publicly, told this publication that compliance with the proposed rules would require renegotiating supplier contracts that in some cases run to 2030 and rewriting industrial strategy documents that had been built around assumptions that no longer hold. "We are being asked to solve a ten-year problem in eighteen months," the official said. "The intent is right. The timeline is not."

Beijing's Countermove

The sulphuric acid export halt is the most recent in a series of moves that suggest Beijing is not passive in this restructuring. Since 2023, China has imposed or tightened export controls on gallium, germanium, graphite, and antimony — all materials essential to semiconductor manufacturing, EV batteries, and defence applications. The pattern is consistent: each control measure is announced as a routine administrative action, framed in state media as a reflection of China's right to manage its own resources, and delivered with enough technical justification to make it difficult for Western governments to file formal WTO complaints.

The sulphuric acid decision is instructive because it targets Australia, a country that has actively pursued supply chain diversification and that hosts some of the most advanced rare earth processing capacity outside China. Australian miners and battery manufacturers had spent three years building alternative supply routes specifically to reduce Chinese leverage. The halt, reported by SBS News as creating immediate uncertainty for EV battery producers in Queensland and Western Australia, suggests that Beijing's calculus is not simply economic. It is also political: a signal that countries which move too deliberately to reduce their Chinese dependencies will face consequences, and that those consequences will be calibrated to the level of diversification effort.

Chinese state media coverage of the export controls has been consistent in framing. The Global Times, in a response to Western criticism, characterised the measures as "routine quality and safety inspections" that reflected China's right to manage its resource exports responsibly. The framing is deliberately mundane — not a strategic weapon, just paperwork. That framing is itself part of the signal. Beijing does not need Western governments to believe its public explanation. It needs enough legal cover to prevent formal trade action, and it has calculated — probably correctly — that the current WTO framework has no mechanism to respond quickly to export controls framed as regulatory rather than political.

The Taiwan Variable

Underlying both the Brussels regulation and the Beijing export controls is a contingency that senior officials in Washington have begun to discuss publicly: the possibility that cross-strait tensions escalate within the next five years. Reporting from Polymarket's aggregated signal on 17 May 2026 noted that top US officials have assessed, in internal deliberations that have partially leaked to policy circles, that the window for a Chinese move on Taiwan may be narrowing from the decade-plus estimates that prevailed through 2023 to something closer to five years. That assessment — whatever its precise provenance — has entered the policy bloodstream in a way that is now influencing industrial planning in ways that go beyond normal commercial risk assessment.

The logic is not hard to follow. Taiwan produces the overwhelming majority of the world's most advanced semiconductor chips. China produces the overwhelming majority of the components and raw materials that go into everything from consumer electronics to weapons systems. A conflict or blockade involving Taiwan would create simultaneous supply shocks across both chains — a chip shortage and a material shortage hitting at the same time, cascading through every industrial economy simultaneously. Governments that have spent the past four years trying to reduce Chinese supply dependency are now confronting the possibility that their efforts, however well-intentioned, may be insufficient if the scenario they are planning for actually arrives.

The five-year timeline — if it is accurate — is significant because it shortens the window for the kind of deliberate, phased industrial restructuring that economists typically recommend. Reducing Chinese semiconductor dependency requires building new fabs in Europe and the United States, which takes seven to ten years at minimum. Reducing Chinese battery dependency requires developing new mining projects in Africa, South America, and Australia, which takes five to fifteen years depending on permitting timelines. Reducing Chinese rare earth dependency requires building processing capacity that simply does not exist at scale anywhere outside China. The EU's proposed regulation operates on the assumption that companies can restructure their supply chains within two to three years. The Taiwan contingency, if taken seriously, suggests that the timeline may be considerably shorter than that.

The Cost of Rearrangement

It is worth being precise about what the current restructuring effort actually involves, because the public framing — "de-risking," "friendshoring," "supply chain resilience" — tends to smooth over the enormous economic costs that are already materialising. Building semiconductor fabs outside East Asia costs two to three times what equivalent facilities cost in Taiwan or South Korea, primarily because the specialised workforce, supplier networks, and institutional knowledge that make fabrication economical do not yet exist at scale in Europe or North America. The US CHIPS Act and the EU's equivalent programs have committed roughly $100 billion in public subsidy to address this gap, but public subsidy alone does not create an ecosystem. The Arizona TSMC facility, which broke ground in 2022, has faced repeated delays partly because of workforce shortages that required importing engineers from Taiwan — a workaround that, somewhat ironically, deepens rather than reduces geographic concentration in the short term.

The battery sector faces similar dynamics. European and North American battery gigafactories announced since 2021 have been consistently delayed by supply chain constraints that trace back, yet again, to China. The equipment needed to coat and assemble battery cells — the core machines in a gigafactory — is manufactured primarily by a handful of Chinese firms, with lead times stretching to two years. European manufacturers building gigafactories in Sweden, Poland, and Germany have found themselves waiting for Chinese equipment while Chinese competitors, operating with established supply chains and shorter lead times, continue to expand capacity faster than Western rivals.

This is not an argument against the restructuring. It is an argument for honesty about its costs. The current policy consensus in Brussels and Washington treats supply chain resilience as a straightforward strategic good, achievable by sufficient regulatory pressure and public subsidy. The evidence from the past three years suggests something more complicated: that the efficiency advantages embedded in China's industrial ecosystem are not easily replicated, that the timeline for building alternatives is longer than the political conversation acknowledges, and that the risk being mitigated against — Chinese leverage over critical supply chains — is itself partially a product of the speed at which those supply chains were offshored in the first place.

What Comes Next

The next 18 months will test whether the EU's proposed regulation can survive the lobbying process intact. Industry groups — automotive manufacturers, solar panel installers, semiconductor companies — have already begun preparing objections, arguing that the 65 percent threshold is technically unachievable for certain components in the required timeframe. The Commission's response will shape whether the regulation becomes a genuine structural change or a political gesture that companies work around through compliance theatre rather than genuine diversification.

Beijing's response will be equally instructive. The export control toolkit is effective but not unlimited. Each control measure that triggers Western counter-investment in alternative supply chains chips away at the long-term market position that Chinese manufacturers have spent decades building. The calculus for Beijing is whether short-term leverage gains are worth the medium-term erosion of market share. Current signals suggest Beijing is willing to accept that trade — at least for now.

The Taiwan question hangs over all of it, not as a certainty but as a probability estimate that has been revised sharply upward in recent months. If the five-year window is real, the current pace of restructuring is insufficient. If it is not, the West will have spent enormous political capital and economic resources on a contingency that did not materialise. The honest position is that nobody knows which is true, and that the policy framework being built is a bet on one of two futures that cannot both occur.

This publication covered the EU's proposed supply chain regulation with a stronger emphasis on industrial feasibility than the initial Financial Times wire, which foregrounded the political dimension. The sulphuric acid export halt was framed by SBS News as an Australian trade dispute; we have situated it within the broader pattern of Chinese export controls as strategic instruments.
