On the morning of February 1979, 17, the Vietnamese army attacked six provinces1/counties in Vietnam with nine armies from Guangxi and Yunnan. Some fighters of the Air Force took off to patrol our border, and some warships of the Navy entered the Beibu Gulf to defend the oil platform.
By March 4th, our troops on the Eastern Front had penetrated 20 to 40 kilometers into the enemy's depth and occupied Gaoping, lang son, Heguang, Chaling, Guanghe, He 'an, Tongluo, Shi 'an, Chongqing, Changting, Wenlang, Gao Lu, Lu Ping, Deng Tong and other towns and strategic places. On the western front, our army broke through enemy lines for 40 kilometers and captured Laojie, Tang Tang, Basha, Baosheng, Meng Kang, Fengtu, Sabah, Guo Shen and Pawu. The important town in northern Vietnam was controlled by our army, which formed a situation of bullying Hanoi and achieved the strategic goal of counterattack. On March 5, the military commission issued an order to withdraw troops. The troops retreated alternately under cover, scorching the earth all the way. All the machinery and equipment that can be taken away were taken away, and all the public property that can be destroyed was destroyed as punishment. When some troops with heavy casualties retreated, they shot blindly and desperately to vent their resentment. On March 13, all our troops on the western front withdrew to China, and on March 16, all our troops on the eastern front withdrew to China, ending the self-defense counterattack against Vietnam.
Border conflicts continued throughout the 1980s, including the Battle of Laoshan and the Battle of Two Mountains in 1984. 1999, after years of negotiations, China and Viet Nam signed a border treaty, but the specific demarcation line remains confidential. The treaty included minor border adjustments and the return of some land to China. Vietnamese official media reported that the new border was actually implemented around August 200 1 year.
