A little remembered aspect of the Korean War is an issue of great importance to those concerned with arms control and allegations of the use of Weapons of Mass Destruction (WMD), namely nuclear, biological, and chemical weapons. During and after the war, North Korea, China, and the Soviet Union alleged that the United States used biological weapons (BW) on an enormous scale in areas of both China and North Korea. Despite the public disclosure of Soviet Central Committee documents in 1998—eighteen years ago—which revealed that the allegations were fraudulent, China and, much more noisily, North Korea still maintain the charges.[1]

The purpose of this Working Paper is to describe recent publications in Chinese journals of an unprecedented nature on the subject. A memoir by Wu Zhili, Director of the Chinese People’s Volunteer Army Health Division during the Korean War, describes the allegations as a “false alarm” and reveals that there was no use of biological weapons by the Americans in the war. Although he does not go as far as to admit that the allegations were really active fraud and disinformation, much of his narrative makes that evident. Two other publications by Qu Aiguo, a Senior Colonel affiliated with the PLA Academy of Military Science History, evaluate, for the first time, the Soviet documents released in 1998. Qu moves away from the standard-line that “the US used BW against China and North Korea” and concludes that “we cannot deny that that the Americans used BW.” Although only a change of a few words, it is a significant shift in the Chinese presentation of the issue.  Nevertheless, it remains dishonest.
