The Korean conflict was a pivotal event in China's modern military History, constituting an important experience for the newly formed People's Liberation Army Air Force (PLAAF), not only as a test case for this fledgling service but also in the later development of Chinese air power. Xiaoming Zhang fills the gaps in the history of this conflict by basing his research on recently declassified Chinese and Russian archival materials and interviews with Chinese participants in the air war over Korea. Zhang's findings challenge conventional wisdom as he compares kill ratios and performance by all sides involved in the war, addresses how air power affected Beijing's decision to intervene, and touches on ground operations and truce negotiations during the conflict. Zhang also offers considerable materials on the training of Chinese aviators and the Soviet role in that training, on Soviet and Chinese air operations in Korea, and on diplomatic exchanges over Soviet military assistance to China.
