Why Taiwan isn't making enough computer chips. Ed Butler speaks to Jan-Peter Kleinhans, head of technology and geopolitics at SNV, a German think tank, about the central role of Taiwan in the complex global supply chain of semiconductors. The BBC's Theo Leggett explains why the car industry has been particularly hit by the shortage of chips. And Shelley Rigger, professor of East Asian politics at Davidson University in the US, discusses the growing significance of Taiwan in the technology war between China and the US.
