Tong Chup massacre information

The Tong Chup massacre (Vietnamese: Thảm sát Tổng Chúp) was a war crime committed by the People's Liberation Army of China during the Sino-Vietnamese War of 1979. The incident happened in Tong Chup village, Hung Dao commune, Cao Bằng city. From February 17, 1979, the Chinese Liberation Army simultaneously attacked Vietnam along the northern border between the two countries.^[1]

Since the Sino-Vietnamese border region was inaccessible to foreign correspondents during the war, Vietnamese claims was never independently verified, and the incident was largely unknown outside Vietnam. Similarly, the death toll of the massacre is unverifiable. Associated Press journalists visiting Tong Chup in 1987 cited Vietnamese officials that the number of deaths was higher than the 504 killed in Mỹ Lai massacre according to Vietnamese statistics ^{[2][verification needed]}
