172 | Hong Kong

What is happening in Hong Kong? We talk to a professor of Chinese history and a Hong Kong journalist about the recent wave of protests there and try to discover what is really at stake on all sides. Who are the protestors? What are their core demands? Can these be met? And what will happen if they aren't? Plus we explore the parallels with other protest movements around the world and look at the possible knock-on effects, from Beijing to Taiwan. With Hans van de Ven and Angus Hui.
