Why China Wants Control of More of the Technology Supply Chain

When China tightened controls on rare earth exports in April 2025, the consequences did not stay inside China. Automakers and other manufacturers abroad scrambled to secure magnets, and some production lines faced shortages. The episode exposed a basic fact of modern industry: a country need not dominate every stage of a technology to exert influence over it. Sometimes control of one difficult-to-replace ingredient is enough. [6] [8]

That leverage is one reason China wants greater control over its technology supply chain. Another is vulnerability. Advanced chips, chipmaking equipment and other critical technologies remain tied to foreign suppliers and export rules. Beijing’s response is to build more of the chain at home—from foundational research and components to manufacturing and deployment—while retaining the ability to use its existing industrial strengths abroad.

The ambition is neither a complete retreat from global trade nor proof that China can already produce every critical technology independently. It is an effort to make dependence less dangerous, and to turn selected points of dependence into bargaining power.

Self-reliance is a security policy—and an industrial policy

China’s official policy language makes the priority plain. In outlining the 2026–2030 science and technology agenda, the country’s science minister called for “high-level sci-tech self-reliance,” breakthroughs across key technologies and a stronger national system for coordinating innovation. The named priorities include integrated circuits, industrial machinery and high-end instruments. [1]

The next five-year blueprint, released in March 2026, places AI adoption, chip breakthroughs and foundational research prominently in the national program. Reuters reported that it calls for AI across the economy, from manufacturing to services, and for progress in fields including quantum technology and robotics. Those aims are official commitments, not evidence that China has already achieved leadership in every one of them. [2]

The commercial logic is just as important. Domestic suppliers can serve a huge home market, learn through repeated production, and sell into global markets. China’s earlier “Made in China 2025” initiative set ambitious goals to move up the value chain. A 2025 U.S.-China Economic and Security Review Commission review found that China fell short in some targeted sectors—including integrated circuits—but still expanded capabilities and market share. The report’s broader conclusion was that state support and production scale helped make Chinese manufacturing more competitive. [5]

That combination matters. Support for domestic industry may lower dependence on imported technology, but it can also create firms with the scale to compete internationally. Self-reliance and export ambition are not opposites; they can reinforce one another.

Chips reveal where the leverage lies

Semiconductors are not a single product. A modern chip supply chain depends on design software, manufacturing equipment, materials, specialist talent and factories capable of producing at demanding levels of precision. A country may be strong in some links yet exposed in others.

U.S. rules make that exposure concrete. A 2022 U.S. Commerce Department regulation introduced controls on certain advanced-computing chips and semiconductor manufacturing items, alongside restrictions connected to supercomputer and chip-production end uses in China. It is a legal control regime, not a blanket ban on every chip or every technology trade with China. [3]

RAND’s 2025 analysis of China’s AI industrial policy describes the resulting bind: Chinese firms are developing local chip and software alternatives, but controls on advanced computing chips and manufacturing equipment constrain access to computing power and the ability to manufacture leading-edge processors. The report also warns that controls are unlikely to stop China’s AI progress altogether. State support, private-sector competition and applications across industry can sustain progress even when a particular input is scarce. [4]

This is why the contest concerns the whole stack, not just the fastest processor. Domestic AI accelerators, software platforms, research funding, data centers and industrial customers can create a usable ecosystem before every component matches the world’s best. Conversely, a highly capable chip may be less valuable if the tools to design, manufacture or deploy it are missing.

China’s policy is therefore partly defensive: reduce the risk that a foreign government’s licensing decision can interrupt critical development. It is also a bet that a large home market and state-backed coordination can help local alternatives improve through use. Neither outcome is guaranteed. State investment can accelerate learning, but the U.S. commission’s review also records missed targets and persistent barriers where entrenched incumbents hold specialized expertise and intellectual property. [4] [5]

Rare earths show the other side of the equation

In chips, China seeks to catch up in areas where foreign restrictions can bite. In rare earths, China already occupies a much stronger position in processing and downstream production. The International Energy Agency estimates that China accounts for about 91% of global separation and refining for magnet rare earths, and 94% of sintered permanent-magnet production. These materials and magnets feed into motors, vehicles, wind turbines, electronics and other advanced manufacturing. [6]

The distinction between mining and processing is decisive. An ore deposit is not a ready-to-use magnet. Processing requires specialized facilities, expertise and time to develop. That concentration means supply disruption can impose costs well beyond the mining sector. In 2025, the IEA reported that export curbs coincided with steeply reduced shipments and disruption for some overseas manufacturers; rare-earth prices in importing markets also diverged sharply from prices in China. [6]

China’s Ministry of Commerce says its controls are a lawful national-security measure, not an export ban, and that eligible civilian applications can be licensed. That is Beijing’s stated position. The uncertainty for foreign buyers is whether access will be timely, transparent and predictable in practice. [10]

The important timeline is often missed. China’s April 2025 controls on seven heavy rare earths and related products took effect immediately. A second, broader wave announced in October—including five additional elements and wider requirements—was suspended until November 10, 2026. As of September 26, 2026, the October expansion remains suspended, but the April controls have not been erased. Reuters reported this month that some Chinese suppliers were still declining U.S.-bound shipments despite licences, while companies in several countries faced delays. These reported cases do not establish a blanket cutoff; they do show that a licence is not always the same as dependable access. [7] [8] [9]

So far, China’s strongest leverage comes less from a total prohibition than from the possibility of delay, uncertainty and selective permission in a concentrated market. This can prompt buyers to redesign products, stock inventory or invest in alternatives. It can also motivate customers to spend years building supply chains elsewhere—gradually weakening the leverage that created the incentive in the first place.
