Why China Can't Build Jet Engines: The Limits of Industrial Policy

China’s state-capitalist playbook—marshal national resources, scale a mature technology, and dominate it vertically and horizontally—has won in industry after industry, but it has failed at jet engines for fifty years. The reason is that engines invert every Chinese advantage: they’re a low-margin market where decades-long reliability, manufacturing consistency, and glacial iteration speed matter more than speed-to-scale or cheap capital, and every finished product faces internationally enforced certification barriers that domestic protectionism can’t paper over.

The high-pressure turbine blade illustrates the problem. It must survive gas hotter than lava while spinning under crushing centrifugal load for roughly 30,000 hours without cracking. Meeting that spec required generations of nickel superalloys doped with metals as scarce as rhenium (50 tons mined annually) and ruthenium, plus single-crystal casting that even established makers only pull off at 50–70% yield—a new entrant would sit in the low tens for years. A single blade draws on about 100 companies across 25 U.S. states and 15 countries, and a full engine runs to over 40,000 comparably exotic parts.

That supplier web, refined over decades and concentrated in the U.S., U.K., France, and Germany, is the real moat. Four firms—Rolls-Royce, GE, Pratt & Whitney, and Safran—have powered most of the world’s aircraft for half a century, with even Russia stuck a decade behind. China has poured hundreds of billions into a parallel industry since Deng made it a priority in 1986 and still can’t reach parity. The author frames this not as proof of inevitable Chinese decline or Western supremacy, but as a case study in where deep, distributed engineering networks remain the West’s durable comparative advantage.
