China Holds the Keys to Technologies Its Rivals Struggle to Replace

China Tightens Its Grip on the Technology the World Needs

China’s industrial strength is becoming a central issue in the global competition for technological independence. Countries seeking to expand domestic manufacturing face a difficult challenge: building factories abroad does not necessarily eliminate their need for Chinese equipment, components or production expertise.

Beijing’s latest proposals on technology exports underline that problem. On October 16, China’s commerce and science ministries announced a consultation on adding 40 technologies to the country’s prohibited and restricted export catalogue, covering artificial intelligence, biomedicine and solar manufacturing.

The proposals distinguish between technologies that would face export prohibitions and those requiring permission. Temporary registration requirements were also introduced for relevant technology exports while the revision process proceeds. These measures should therefore not be described as a blanket ban on Chinese technology or finished products.

The power behind the production line

The strategic question extends beyond who sells the finished product. A country can assemble solar panels domestically while depending on foreign suppliers for the materials, machinery and processes that make production possible.

According to the International Energy Agency’s Energy Technology Perspectives 2026, China accounts for approximately 85 percent of solar supply chain manufacturing capacity and 80 percent of lithium-ion battery supply chain capacity. Its share reaches about 95 percent for solar wafers.

Those figures help explain why diversification is difficult. Replacing the final assembly stage leaves vulnerabilities elsewhere in the production chain. The IEA finds that important bottlenecks remain even where manufacturing capacity outside China could theoretically satisfy much of the demand for finished equipment.

Beijing presents a security argument

China’s commerce ministry says the proposed changes address risks associated with sensitive technological applications and are not directed at a particular country.

The proposal includes 23 artificial intelligence technologies, five biomedical technologies and 12 solar technologies. Officials also describe exceptions and simplified arrangements intended to preserve certain forms of international cooperation.

For businesses, the distinction between purchasing a product and obtaining the technology needed to manufacture it is crucial. A company may retain access to Chinese goods while facing additional requirements when transferring particular production processes overseas.

A difficult calculation for other economies

The economic dilemma is clear. Diversification can improve resilience, but duplicating established supply networks requires investment, skilled workers and reliable demand. Governments must consider how to finance that transition while keeping energy and industrial equipment affordable.

The IEA estimates that a month-long disruption to Chinese exports of solar supply chain components could cost solar module factories outside China approximately $1 billion in lost output. This is a modeled disruption scenario, rather than a report of losses already occurring.

For smaller economies, the practical response is to examine dependencies carefully: which components have alternative suppliers, which equipment requires specialized support, and which projects could stall if access changes.

China’s manufacturing position gives it substantial influence. The challenge for other countries is turning ambitions for greater independence into production systems that can operate reliably. A new factory is a beginning; a resilient industrial network requires much more.
