This week on Sinica, Kaiser and Jeremy chat with Peter Martin, a correspondent for Bloomberg based in Washington, D.C., about his book, China’s Civilian Army: The Making of Wolf Warrior Diplomacy. This highly readable and informative book tells the story of China’s diplomatic corps from its creation ex nihilo under the guidance of Zhōu Ēnlái 周恩来 during the Communist Party’s years in Yan’an in the 1930s and 1940s through the foundation of the P.R.C., the vicissitudes of the Great Leap Forward and the Cultural Revolution, and the period of reform and opening up to the current, more assertive, and often pugilistic present under Xí Jìnpíng 习近平.
