The number of casualties during the war is disputed. Vietnamese sources claimed the PLA had suffered 62,500 total casualties, including 550 military vehicles, and 115 artillery pieces destroyed; while Chinese democracy activist Wei Jingsheng told western media in 1980 that the Chinese troops had suffered 9,000 dead and about 10,000 wounded during the war. Leaks from Chinese military sources indicate that China suffered 6,954 dead.
