In the final episode of this season of Tech Tonic, we ask if the growing tensions between the US and China could split the world into two competing technological spheres. It has been dubbed 'the great decoupling'. Some in the US want to see Chinese companies cut off from American investment, while hawkish factions in China have been fighting for a more self-sufficient and nationalistic tech sector. But what would decoupling really look like? And is it even possible?   Presented by James Kynge, this episode features interviews with Lillian Li (author of Chinese Characteristics newsletter), Paul Triolo (senior vice-president of Albright Stonebridge Group), Roger Robinson Jr (president and founder of RWR Advisory) and Kevin Rudd (former prime minister of Australia and president of the Asia Society)   Check out stories and up-to-the-minute news from the FT’s technology team at ft.com/technology For a special discounted FT subscription go to https://www.ft.com/techtonicsale And check out FT Edit, the new iPhone app that shares the best of FT journalism, hand-picked by senior editors to inform, explain and surprise.
