Huawei: Who are they?

Is the telecoms equipment provider a front for Chinese espionage or just the victim of the escalating US-China dispute? Why don't Western governments trust the company to handle its citizens' data? Following the controversial arrest in Canada of Huawei's finance head Meng Wanzhou, the BBC's Vishala Sri-Pathma asks whether the move is just the latest step in a tech cold war between the US and China. She speaks to Rand Corporation defence analyst Timothy Heath, tech journalist Charles Arthur, and China tech podcaster Elliott Zaagman.
