This month, China has been marking the 25th anniversary of the handover of Hong Kong, from British rule back to China. For many Hong Kongers, this was not a day of celebration - including for Samuel Chu, a Hong-Kong born American activist, founder and President of the non-profit group Campaign for Hong Kong. His father, a retired pastor, was one of the leading figures behind the Occupy Central movement, the pro-democracy mass movement that sparked the Umbrella Revolution in Hong Kong back in 2014. As the first foreigner wanted by China under China's National Security Law, Samuel joins Julia Macfarlane to discuss how China’s actions in Hong Kong may inform Taiwan’s future, while Sir Richard Dearlove reveals new details about the negotiations and his scepticism of China during this time.
