How dangerous is the superpower rivalry in technology and information? Currently there’s much focus on the tensions between the US and China over the Chinese tech giant Huawei. Soon 5G networks will be a critical part of our world in transportation, power supply, payment systems and so much more. Washington says the Chinese can’t be trusted because they may use their technology infrastructure for spying.  Beijing says this is nonsense. HARDtalk's Zeinab Badawi talks to the US top official on cyber information and security, Robert Strayer. He’s on a mission to dissuade Europeans from doing business with Huawei. But is Washington losing the cyberwar? Image: Robert Strayer (Credit: Shawn Thew/EPA)
