Economic separation between deeply integrated states is not a clean break but a targeted unwinding of specific high-stakes dependencies, particularly in semiconductors, telecommunications, and data infrastructure. Full separation is impossible without catastrophic cost, so 'decoupling' really means raising the walls around strategic sectors while leaving lower-stakes trade intact.
Whoever controls the foundational technologies of an era — currently AI, semiconductors, quantum computing, and biotech — sets the terms for military power, economic dominance, and norm-setting. The US-China contest is therefore fought primarily over who leads in these specific technical domains rather than over territory or ideology directly.
When a state deliberately integrates its commercial technology sector with its defense and intelligence apparatus, the distinction between civilian and military products collapses. This means any technology transfer to such a state must be assumed to have military application, which justifies export controls that would otherwise seem economically irrational.
Global supply chains contain narrow nodes — like advanced lithography machines or specialized chip design tools — controlled by a handful of firms or countries. Mapping these chokepoints reveals where one power can strangle another's technological progress, turning interdependence into a weapon rather than a mutual restraint.
Power in technology accrues to whoever writes the technical standards that govern how systems interoperate, because adopters become locked into the standard-setter's architecture and values. The competition over bodies like the ITU and over 5G or AI protocols is a fight to embed one's preferences into the invisible infrastructure that everyone must use.
How a state treats data — as a privacy-protected individual right versus a state resource for surveillance and control — exports its political model through the technology it deploys abroad. The spread of a country's digital infrastructure therefore spreads its governance model, making data architecture a vector for ideological influence.
