US export controls on high-end semiconductor chips, and Chinese control over rare earth supply, are just the most recent examples of major economies weaponising chokepoints in the global economy. Paul and Luke speak to Edward Fishman, a former US State Department sanctions official, Colombia University professor, and author of “Chokepoints: How the Global Economy Became a Weapon of War”, about the US’s and increasingly China’s control over these chokepoints, how financial and legal chokepoints arise out of the structure of the modern global economy, and how major powers use chokepoints to pursue their geopolitical interests.
