Money Talks: Out of (export) control

The US government is intent on keeping the most advanced semiconductor chips—and the technology required to make them—out of China's hands. In the last two years a barrage of export controls have been put in place to do this. But creating a watertight system in a deeply interlinked global economy is difficult, verging on impossible. It will only work if America's allies are on board.  Hosts: Mike Bird, Tom Lee-Devlin and Alice Fulwood. Guests: Maria Shagina, senior research fellow at the IISS, and Gregory C. Allen, an export controls expert at CSIS. Sign up for a free trial of Economist Podcasts+.
