Chinese casualties
The number of casualties during the war is disputed. Shortly after China had announced the withdrawal of its troops from Vietnam, the state-run Vietnam News Agency claimed that the PLA had suffered over 44,000 casualties, a figure which Western analysts at the time considered to be greatly inflated.[85] Other Vietnamese sources claimed the PLA had suffered 62,500 total casualties, including 550 military vehicles and 115 artillery pieces destroyed.[86] Leaks from Chinese military sources indicate that China suffered 6,954 dead.[1][5][87]
Deputy chief of the General Staff Wu Xiuquan revealed in a meeting with a French military delegation that Vietnam suffered 50,000 casualties, whereas China had suffered 20,000 casualties. Regardless of the accuracy of the Vietnamese casualties, it can be concluded that the Chinese losses were severe, according to Daniel Tretiak.[88]
Vietnamese casualties
Like their Chinese counterparts, the Vietnamese government has never officially announced any information on its actual military casualties. China estimated that Vietnam lost 57,000 soldiers and 70,000 militia members during the war.[89][90][91] The Vietnamese state newspaper Nhân Dân claimed that Vietnam suffered more than 10,000 civilian deaths during the Chinese invasion[92][93] and earlier on 17 May 1979, reported statistics on heavy losses of industry and agricultural properties.[92]
Prisoners

The Chinese held 1,636 Vietnamese prisoners and the Vietnamese held 238 Chinese prisoners; they were exchanged in May–June 1979.[9][10]
