China has warned that rising protectionism is splitting global supply chains into rival blocs, and its own controls on rare earth exports could accelerate a shift that hits technology and defense companies hard. The warning, which came from Chinese officials in recent days, frames the fragmentation as a threat to global economic stability — even as Beijing tightens its grip on critical minerals the rest of the world depends on.
The Warning on Fragmentation
In a statement that touched on the broader trade environment, China pointed to a surge in protectionist measures around the world. The country's leaders argued that such policies are unraveling decades of integrated supply networks. While the language was measured, the timing was pointed: it arrives as many governments push to reduce their exposure to Chinese manufacturing and raw materials.
Rare Earths at the Center
China dominates the rare earth supply chain, controlling roughly 60% of global mining output and an even larger share of processing. Its export restrictions on these critical minerals — used in everything from smartphones to fighter jets — could push buyers to diversify sources. That process, already underway in the United States and Europe, may speed up as China tightens the tap. The restrictions aren't new, but their scope and enforcement have grown more aggressive in recent months.
Tech and Defense in the Crosshairs
The technology sector relies on rare earths for magnets, lasers, and electronics. Defense applications, including guidance systems, radar, and advanced communications, are also heavily dependent. Supply chain diversification means higher costs and potential delays for now. But it also offers a long-term reduction in vulnerability to Chinese export controls. Companies in both sectors are scrambling to line up alternative sources, from Australian mines to recycling operations in Japan.
The question now is whether other countries can ramp up their own rare earth production fast enough — or whether China's dominance will only deepen as the global economy fragments further.
