More than a year after Xi Jinping purged two senior generals in the People’s Liberation Army Rocket Force unit, China’s investigation into its military seems to be ongoing, with more scalps taken. In recent weeks, Miao Hua, another senior general who had been a member of the Central Military Commission, has been suspended; while reports abound that the country’s current defence minister, Dong Jun, is under investigation too. If suspended, Dong would be the third consecutive defence minister that Xi has removed. To paraphrase Oscar Wilde, to lose one defence minister may be regarded a misfortune; to lose three looks like carelessness.

So what is happening at the top of the PLA? Is all of this movement a sign of Xi failing to get on top of corruption within the military or, in fact, a sign that he is gearing up for serious military action, perhaps over Taiwan? Just how effective have the military reforms that Xi instigated in 2015 been?

Joining the podcast today are Oriana Skylar Mastro, an expert on the Chinese military at Stanford University and author of Upstart: How China Became a Great Power, and Demetri Sevastopulo, US-China correspondent for the Financial Times.
